No Battery Is Detected Vista Hp G60

In the following guide I explain how to remove and replace damaged LCD screen on HP G50/G60/G70 notebooks. I’m replacing it on a HP G50 but all disassembly steps should be almost the same or at least very similar for HP G60 and G70. By the way, HP G50/G60/G70 models also known as Compaq Presario CQ50, Presario CQ60 and Presario CQ70. In most notebooks you can replace the screen without separating the display panel from the base but not in HP G50/G60/G70. In these models we’ll have to remove display panel first. By the way, in the next post I show how to.

No Battery is detected?? I have a very similar problem. Hp Envy No Battery Detected. HP G60 - Abrupt battery failure, battery not. Abrupt battery failure, battery not detected. Replaces Battery No. HSTNN-LB72 484170. HP Pavilion dv4, dv5, dv6, G50, G60. HP G50 G60 G70 series laptop batteries and a host more which are.

You can find the HP spare part number in the service manual. I linked to service manuals at the end of this guide.

Turn off the laptop and remove the battery. Remove one screw securing the Wi-Fi cover and remove the cover. It is not necessary to remove the memory and hard drive covers. I marked them just for your convenience. Remove three (yellow) screws securing the keyboard. Remove four (red) screws securing the keyboard cover. If you are using this guide for replacing the keyboard, you have to remove only three (yellow) screws.

In G50 and G60 the keyboard screws are located in the battery compartment. In G70 notebooks there are only two screws securing the keyboard and they are located on the bottom (there is a small keyboard stamped close to each screw). Carefully lift up the keyboard from the base. Place the keyboard so you can access the cable connector underneath. You have to unlock the connector and release the cable before removing the keyboard. Move the white clip about 2-3 millimeters towards the display panel and release the cable. Now you can remove the keyboard.

The white clip must stay attached to the connector base. If you accidentally break the connector, you’ll have to replace the motherboard.

If you work slowly, everything should be fine. On the picture below the connector is shown in the unlocked state.

Disconnect the switch board cable from the motherboard. Remove the keyboard cover. Move the cover towards the display to separate from the top cover. Turn the laptop upside down and disconnect two antenna cables from the wireless card. Each antenna cable has a golden head. Grab the head with your fingers and lift it up.

Disconnect the video cable connector from the motherboard. Disconnect the webcam cable from the motherboard. Pull two Wi-Fi antenna cables through the opening. Remove four screws securing the display panel hinges. Lift up and separate the display panel from the base. In the following steps we will disassemble the display panel and remove the LCD screen.

There are two screw seals located in the lower left and right corners. Remove these seals with a sharp object and remove screws found under the seals. Start separating the bezel from the display cover.

Continue separating the bezel. The bezel has been removed. The inverter board is mounted on the bottom side of the display cover. The inverter is locked between plastic brackets. You can remove and replace the inverter board without removing the screen.

Simply pull the inverter board from the cover and disconnect connectors on both ends. Remove two screws securing the right display hinge. Remove the right hinge. Remove two screws securing the left display hinge.

Remove the left hinge. Remove the inverter board from the cover and disconnect one connector from the right side. By the way, this is the backlight connector. Remove two screws securing the mounting brackets on the top.

Now you can separate the LCD screen from the display cover and access the video cable. My HP G50 notebook didn’t have the webcam installed and the webcam cable was taped to the display cover. If you have a HP G60/G70 notebook, most likely it came with the webcam. You’ll have to disconnect the cable from the webcam before disconnecting the video cable. Remove sticky tape securing the video cable connector and unplug the video cable. Now you can remove the LCD screen from the cover. If you are replacing it, you’ll have to transfer the left and right mounting brackets to the new screen.

Remove three screws securing the bracket and remove the bracket. Do the same with the other side. The LCD screen model number is located on the sticker. In my laptop I had this model installed: B154EW08 v.1 The HP part numbers for LCD screen and other parts can be found in service manuals and here they are.

Francisco, I have a HP G60-120US it fell and now the screen is black, if you put it almost horizontally you can see all the start menu but very dim. Could it be the connector, the LCD or back light? It works fine with an external monitor 1. It’s possible that the video cable got disconnected from the inverter board. Try reconnecting the cable.

Could be damaged backlight lamp inside the LCD screen. You’ll have to replace the backlight which is not easy or replace the whole LCD screen. Also, the problem description sounds like a failed inverter board but I don’t think this is the problem. I don’t think that inverter can get damaged if you drop the laptop. Most likely it’s related to the backlight lamp. reneviht, I got stuck in step 5; I can’t tell which part I’m supposed to move to disconnect the switch board cable.

I’m guessing it’s the off-white part, since the off-white part in step 4 was the one that was supposed to move, but nothing’s budging. Is there any chance someone could elaborate? I made this tutorial a while ago and do not remember exactly the connector type used in this model. I believe this connector has two parts. The white base and black locking clip. The clip opens up like a door and it has small hinges on one side. You lift up one side of the clip (closer to the LCD screen) at a 90 degree angle.

When the clip is open, it releases the cable. You should be able to pull the cable. Jim Darrowugh, I also have a CQ50. If the LCD is moved, it will sometimes exhibit random lines and what I would call hash. If I move the cover back and forth, but not too close to closed of course, it usually remedies the problem.

Did you have a chance to test video on the external monitor? I assume that external video is fine, which means it’s not the video card or motherboard problem. Is this likely to be just a loose connection on the mainboard or do you think the video cable could be broken? It’s hard to tell without looking at the laptop.

Could be one of the following: 1. Bad connection between the video cable and LCD screen or motherboard.

Reconnecting the cable on both end might fix the problem. Defective video cable. LCD screen failure.

Lisa, I want to replace a damaged monitor from being dropped with another monitor from a different laptop I found for sale but how do I tell if they are compatible or not? My computer is a dv9815nr and the other computer is a dv9715 will it work? I cannot tell. Sometimes manufacturers install different screen even into the same model. You’ll have to compare screen specifications. If both screens have the same resolution, there is a good chance that this replacement will works.

By the way, here’s my guide for k. Beverly, I just relpaced a laptop LCD compaq perasiro CQ60 an now the screen is all white and ideas?

Could be bad connection between the video cable and LCD screen. Try reconnecting the video cable on the back of the screen. Make sure the connector plugged correctly. If there are pins inside the connector on the LCD, make sure there are no bent pins. Dont tell me I have to take it all apart again. Try reconnecting the cable without taking it apart and if it doesn’t work take it apart and try reconnecting again.

Thanks for this posting, the instructions, very detailed and easy to follow. My brother changed the lcd on my compaq cq60 pretty easily. I sent my laptop out to HP service support, thinking they would cover it under their warranty. Boy was I disappointed when they said they wouldn’t fix it under the warranty and wanted more than I had spent on the computer to replace the screen. I need help though. When I first sent them the laptop, there was a big black spot (the crack) and a white background with colorful lines going across the screen, but if hooked up to an external monitor, that monitor would show a perfectly clear picture.

When I got the computer back, there was just the crack and a plain white background, no lines in it. After my brother put the new one in, there was still just a plain white screen, and when hooked up to an external monitor, the picture doesn’t come up, there’s just a message about that monitor going into sleep mode. Could HP have damaged something when they were looking at the computer before they shipped it back? Great site, thanks!

I just replaced a broken LCD screen in my son’s G60. The old one was cracked, but the backlight worked. Now, the display works but the backlight will not come on. (I reconnected the old screen, still no backlight). All connections appear tight.

I am assuming it must be either a) bad ribbon cable to the inverter (although data to the screen seems to pass ok), b)the inverter went bad while changing the screen, c) backlight bulb is burnt out (unlikely since both screens do not have backlight), or D) the cover closed switch is stuck in “closed” condition. Which brings me to my question.WHERE the heck is this internal display switch? I cannot locate it on this laptop at allIn the online manual (another big THANKS!) it shows it vaguely in section 2-1, but never mentions it again, not even as a part number.

Can you provide any clue as to where it is located? Also, if the inverter is good, what voltage should I be looking for on the output side? Thanks again! Steve, the cover closed switch is stuck in “closed” condition. Which brings me to my question.WHERE the heck is this internal display switch?

I cannot locate it on this laptop at all I believe this laptop might have a magnetic switch. There is a small magnet mounted somewhere under the screen bezel and when the display is closed, it activates the switch under the cover. Find a small magnetized screwdriver and move it slowly alone the perimeter of the screen bezel. You’ll feel where the magnet is located and this will help you to find the switch. Here’s what you can try. Connect the new screen to the laptop but instead of plugging the backlight lamp from the new screen, plug in the old screen.

Can you get the backlight this way? I’m just trying to generate some troubleshooting ideas. Check connection between the video cable and motherboard/LCD and inverter again. Wow, thanks for the very quick reply! I had already tried the old screen, but re-verified it, still no backlight.

I checked the inverter output with a VOM meter, no dc voltage at all. Triple-checked the cable connections, all seems ok unless internally broken.I can always ring them out but doubt this is the issue. Thanks for the info re: the cover switch, I found the magnet on the bezel, which helped me locate the (impossibly tiny) switch inside the frame over the battery compartment. It looks (judging from a flashlight through a crack wedged by a screwdriver) as though the leads to the tiny reed switch are broken away from the switch. I dont *think* I did this removing the bezel, but anything is possible. I tried shorting out the leads with two screwdrivers (if it doesnt work with the circuit open, it must be looking for a closed circuit, right?) but no luck.

At this point I am thinking I need to crack the case to get to the switch and make sure I am shorting across it to close. Either that or try to find an inverter (this one is an oddball part number and not much luck finding compatibility lists online) and throw parts/$$$ at it. Hope I can get this going, son is deployed US Army and this laptop is his commo link to home; if not I will have to buy a replacement for him. A sincere THANK YOU for your help and advice! Thank you very much for all of your help.

I broke the LCD on my laptop and purchased a new one. Well, it didn’t seem like rocket science since i am pretty technologically savy, just to remove the screen bezel and unscrew the brackets and such. However, to my dismay, when I unscrewed the screen brackets, something was just not right and the left one broke, so I had to purchase a new one. Come to find out, I needed to remove a lot more than what was expected, due to my research on online and I came across this website.

I have a compaq presario cq50-130us and this website helped me to a “T”! My laptop is now prestine thanks to you!!! I am having the same problem as experienced by Joshua and Adam in post 47 and 48.

I have double and triple checked the connections and have also tried reattaching the cracked lcd which now also experiences the same problem so I am convinced it has something to do with the internal display/cover closed switch. I have found the magnet on the underneath of the bezel but I am at a loss what to do know. Is there a physical switch somewhere? Post 43 refers to an “impossibly tiny switch” but cannot see one. Been at this for about 5 hours now (currently 2:15am) so head is fried.

Any help would be greatly appreciated. Thanks so much for this site – I would almost certainly have spent a fortune getting my laptop fixed, but following your instructions meant that I only had to pay for the replacement screen! I followed your instructions and it worked!

But as I put it back together I broke the switchboard connector (only the black bit that sits on top to hold the ribbon/cable in place) I made sure I put the cable in place properly and it actually worked! Power, hard drive, screen everything! The problem is that it has since stopped working completely – like Tom (post 44) and Joshua (post 47).

I had a feeling that the cable could have just slipped out of place, so I opened the laptop back up and re-fitted the cable again; and again it worked! Everything was perfect! However, it has since stopped working again, and despite two attempts to fix it this evening (using electrical tape to hold it in place!) it still won’t power-up at all. I’m totally at a loss, so any advice on what to do now would be much appreciated! hey mate, i had the same drama as u, unfortunately it was embarrasing that it took me 6 hours back and forth in frustration.

BUT make sure the actual video plug on the back of new lcd is pushed ALL THE WAY in. I was checking everythin,looking for this mysterious switchetc.and after the 4th time of pulling it apart, i thought, maybe the connection to the lcd wasnt all the way in cause all the others were definately secure.low and behold, it went in alot further than i originallly had it, put it all together and then it works. Make sure that the power to the motherboard is secure as it tended to come out fairly easily unless you secure it properly.

All the best with it. I have a compaq cq60.

I had a painting fall off a shelf and shatter the screen, it actually hit the closed lid and smashed its way through, i couldn’t believe something so light could cause so much trouble. I ordered a new screen and found this pagemy only advice is to be a bit more specific on how to open some of the clips that secure the various cables.

Specifically the switch board cable, for the power button, it opens by lifting the black clip toward the touch pad, and the fact that you have to pull with more force than you would think to pull out the webcam cable and that the video cable needs to go in until you don’t see any part of the metal, (all the way in with gentle but steady pressure). Otherwise, the instructions were dead nutz accurate, it was my first time working on a laptop and it was a success.

Yee Haw Tried taking it apart again (actually I took apart everything as per the pdf manual) and it worked. Made sure that I pushed the cable in far enough as per Dan’s post 56. Delighted – thanks for the guide. Only problem is now that I have lost the switch board connector. I have borrowed the one from the touchpad in order to ensure I am getting power and am using a usb mouse instead, however this is a pain in the ass. I have searched everywhere for this part number but I cannot find it. Just wondering if anyone knows what it is.

Claire (post 55) sounds like you might be in the same place as me having broken it. Again just to clarify its the black comb connector that sits on top to hold the ribbon/cable in place). Any help would be greatly appeciated Regards Stiofain •. Thanks for the great instructions!

I much appreciate it. I dropped my brandnew laptop within just a few weeks of purchase and could not believe how expensive it was to have repaired. In case any of you are looking for a screen, a company called “Bliss” computers has compaitibility screens for our G50 laptops for $89.00. Check them out. I never would have tried to take on the challenge of replacing my laptop screen until I found this site. The only problem I ran into (the whole process took me about one hour and 45 minutes,) was STEP 5. Disconnect the switch board cable from the motherboard.

There is a little piece of strong plastic, (a little tab) right at the point of connection that you are supposed to use to pull the wire harness out, and use the same tab as leverage to slide it back in.(pull it towards you back into the clip or whatever its called.) if the black piece of plastic comes off, there is a small arrow that should be up and facing you to put it back in place, and then slide the harness back into it. So, the harness slides in with the clip already fully secured. I hope this may help anyone who may run into this problem. Don’t be afraid to use a liitle, and I mean a little bit of force pulling it out and back in!

(yeah yeah I know, that’s what she said.) •. my sister dropped her laptop. Hooked it up to a monitor to confirm it still worked and just the lcd broke. Ordered the correct model. Use your instructions to remove the old one and installed the new one flawlessly.

Began to reassemble the laptop. Before completly putting it back together, i tested the laptop to make sure the screen was installed correctly. Compaq bios screen appeared so i turned it off. Finished putting the keyboard on and all screws. Then went to turn it on and nothing. The battery icon flashes three times which is a memory error. Tested to ensure all memory was seated correctly.

Still nothing. I then tested each module and memory slot. Still nothing. Any ideas???? Thanks in advance.

My laptop fell off the bar stool the other day and cracked right on the inverter. I did not notice this until I turned it on and half the screen was dim.

Then after a couple hours of use, the rest of the screen went out. The inverter was bent and cracked around the grey stone looking thing (technical guru here I know;p) I figured that was the only problem but it still won’t light up after replacing it.

I can see windows and everything barely. So next thought would be the lamp? Being that the screen went out half way first I figured I had a dual lamp set up.

However the inverter only has one set of outputs. Before I tear into this thing I was wondering is it possible for a lamp to halfway go out like that? Or does it sound like some other issue? Great site by the way thanks for the great info and easy to read instructions.

Hi, I have an HP G60-243DX, and it came with the webcam. My LCD is busted and my husband would like to use your tutorial to fix it, instead of sending out for repair ($$!!OMG!!$$) My one question beforehand is: Is the webcam separate from the lcd display? Is there anything special we should know before, so that I don’t lose that?

I’m actually using this G60 right now, hooked up to a Dell external monitor and despite the harsh damage to the LCD (it was hit with blunt force), the webcam still works. Well everything still works on it except for the screen 😉 Thanks in advance. After reading all of the comments to this thread, I’m feeling a bit more confident about us doing this repair ourselves. This worked for me!

I had to re-do a couple of parts as there is a learning curve but it took me 3 hours including e-mail and facebook breaks here and there. I’d say this is a 3-4 hour job for the average person. Not fun but saves you $!

** Step 5 was difficult for me and I ended up breaking the sides of the white connectors to get the black cable connector out but it still worked. ***When you re-assemble the LCD screen, make sure you can connect the video and webcam cables in step 8 as they got bunched up and I had to take everything out to get the wires out again. kezy, i followed your instructions and it was very helpfull in replacing my broken screen for my compaq presario cq60. But after replacing it all i get is a solid white screen, ive tried removing the video conector cable a couple of times and putting it back but it still doesnt change. I hooked up the laptop to an externa monitor nand it works perfectly fine.

Why did you replace the screen? Did you replace just the LCD screen or you replaced the whole display assembly (LCD screen, inverter, cable, plastic covers, etc)? Check connection between the video cable and LCD screen. Maybe the cable is not seated correctly. kezy, the laptop fell from a table and the lcd cracked, so i had to get a new one lcd screen.

But before doing that i hooked up the laptop via external cable tp know if it was working fine and it was, even used it for a couple of days before the new screen arrived, so yes i can get video when hooked up externaly to another monitor. The laptop works with an external monitor, it means the motherboard/CPU/memory are OK. Did you get any image on the undamaged part of the cracked LCD screen?

Did you get the backlight? For troubleshooting the problem you can try connecting the original cracked LCD screen back to the laptop to find out if the image is still there. If you get image on the cracked screen but not the new screen, the new screen either defective or not compatible with your laptop. kezy, i put back the cracked lcd screen it intially gave me a white background afte adjusting it it wasnt all white again, it had some black patchs,does it still sugest that the new one is defective It’s hard to tell because you don’t have any image on the cracked screen. Is it possible that your new screen is defective? Yes, but I’m not sure 100%. By the way, you can try reconnecting the video cable on the motherboard.

Most likely this connector is located under the keyboard cover, somewhere close to the left hinge. It’s possible that the video cable got disconnected from the motherboard when the laptop hit the floor.

Just a guess. I was glad to find this guideit was extremely helpful and made the process of trying to switch out my LCD screen very easy.I turned on my laptop and when my compuer was booting up is displayed 6 seperate mini screens with 2 white bars on the screen.when i get into windows I get my desktop to continuely scroll and now i have a 2 inch black bar on the right side. It seems like the whole desktop is being pulled to the left side of the screen and scrolling at an extremely fast rateany suggestions from anyone? Thanks in advance for your answers. Maria, I have an HP G60.

My screen is a bit messed up after my nephew sprayed air freshener all over my laptop. I believe moisture got into my screen.

I can see everything on my screen just fine but there are a few spots that are extremely bright and blotches and streaks. This all looks like just a lil bit of moisture and I wanna know if I can fix it myself using these instructions. Wait for a few day. Maybe the moisture will evaporate. It not, you’ll have to replace the screen or use it as is.

i’ve changed a couple displays before from different computers that had broken lcd displays.but now a friend brought me his computer that has no backlight.his computer runs fine and you can still see the screen just super blacknow another friend told him that he just went on ebay and was able to find the backlight for like 8 bucks. Now ive researched and used the service manual for an hp g60 and in the last pages it shows how to uninstall the backlightbut there is no part number for the backlight.how do i figure out what i needand can you show the steps.it be nice if they were on here. Ticklinivorys, I am having flickering horizontal/vertical lines across my LCD screen, and I was told that I needed to replace the LCD screen.

Does that sound right to you It depends. First of all, test your laptop with video output on the external monitor. Do you have the same problem on the external monitor? If yes, most likely this is video card failure. On the other hand, if external monitor works fine and the problem appear only on the laptop screen, it could be one of the following: 1. Loose connection between the video cable and LCD screen. Bad LCD screen.

Bad video cable. Which one is causing the problem? I don’t know. Try reseating the cable first. After that you’ll have to guess. Try touching/moving the video cable while the laptop is turned on.

Will it affect image on the screen? Will if fix flickering lines for a while? If yes, probably it’s bad cable. If playing with the video cable doesn’t affect image on the screen at all, probably it’s bad LCD screen. Hello, I’ve replaced a couple of these in the past. I’ve just replaced an LCD for a G60, but, when I powered it up, the screen didn’t power up. The power light comes on, the HD light only flashes occasionally.

The only issue I had with the installation was that a couple teeth broke on the power ribbon clip. It still fits in the ribbon holder, and holds the power ribbon down.

Everything else seems fine. I re-installed the old LCD just to see if maybe the screen is bad, but that did the same thing (didn’t power up). Would having some teeth missing on the power ribbon clip have that effect?

Anything ideas what else could be going on? I would appreciate any help.

lincszx, my compaq cg60 sreen has gone dim, is this a screen or inveter problem? I can just make out the screen very faintley and if i plug it into an external moniter it works fine.

Can you give me any advice I cannot tell which one is causing the problem without testing your laptop. Most likely it’s either bad inverter or bad backlight lamp. I would try replacing the inverter board first. If it doesn’t help, replace the LCD screen. Also, there is a chance of bad motherboard or video cable but it’s not very common. chas, i just replaced the lcd cable on my compaq preasrio c700 but now it wont turn on.

When i plug the adapter in on the side the ring around it turns blue which means there is power but it stil wont turn on Can you see any other activities besides the ring around the jack? Something like flashing hard drive light, etc Can you start the laptop with an external monitor if you unplug the LCD cable from the motherboard? Make sure the cable is plugged correctly.

If there are many pins inside the video cable connector on the motherboard, make sure they are not damaged. chas, when i do plug in the charger there is only the light around the ring. The light that flashes to indicates thats it charging doesn’t go on as well. Even we i just leave the battery on by itself it still doesn’t turn on. I think its the power button the physically wont work I believe the light around the ring shouldn’t flash when the AC adapter plugged in.

I think it’s more than just a broken power button. Maybe the adapter is bad? Maybe the laptop will not start form the battery because it has no charge?

Jeff, Yes the sceen is compIetely black, I already tested the memory by reseating them, changing the order and then trying one at a time in both slots. If the laptop doesn’t work with the external monitor and memory is good, most likely this is motherboard failure. As a last resort, you can try minimizing the system as much as you can. Removed battery, keyboard, DVD drive, hard drive, disconnect LCD cable from motherboard, etc leave only motherboard, CPU, memory.

Try turning on with the external monitor. If nothing, probably bad motherboard. A wonderful example of sharing. I have replaced my daughter’s screen successfully saving at least 200$. I would make three additional comments, and ask one questions: 1) you should consider updating the document with the sizes of the screws taken out. I found because I was not organized that I had to try several times before I got the right set of screws in all the right places (well almost, I have two left over that I don’t know where they go) but it works great just the same 2) the screen brackets that you take off fit several ways but only one it correct.

Pay attention to the screen shots. Note specifically that the joints angle in not out. Also very important, take not of how the brackets and the screen edge is flush with each other. When you put them back on they should be the same, otherwise you won’t be able to snap the bezel back in place. 3) much time can be saved if when taking apart your laptop, you are organized.

Keep all pieces removed in each step kept together and apart from the parts on each other step. That way you can easily reverse the process.

I was stupid and did not do this and so I spend five hours putting it back together and unpacking it and putting it back together (rinse and repeat). Eventually I got. So now my question. My original screen was a TL A1. BUT THE VENDOR SENT ME A TLA3.

The screen fits fine and works great, but it appears to me that video playback is much slower. Is it possible that in changing the screen I have confused my system?

It current says “generci PNP display”. Is there a driver for the screen or is generic correct?

Have you heard of slow downs because of screen replacments? What else do you suggest? Thanks, Kevin •. After first disassembly (was looking for screen model number) had to force hdd cover to close (stupid of me, I know). Tried to start my notebook. It powered up (i could hear the fan going, and the power button was lit up) but the screen remained black, the caps lock light and the num lock light started flashing and the wifi button light stayed red, instead of turning blue! Substituted the screen for a new one just today, the problem remains the same!

Before I attempted to disassemble my notebook, but after cracking my screen,(which was the reason I had to substitute it) the nb started up properly, I could still conect it to my tv set through hdmi port, and see everything Could I have broken something while forcing the cover to close! (Or I just forgot to plug some cables back in?) If so, what could it be? What could be the solution? As I assume, the notebook is not dead! My notebook is Compaq Presario CQ61, which is a bit different the model discribed here,(that’s why I had to take hdd cover off) but the cables are all the same and I got to the screen removing part without any problem! Could you please give me some advice?

Your help would be very much appriciated, as i couldn’t find anything, while surfing the net!

Did you remove memory modules? If you did, make sure both memory modules seated correctly. Hi, Thanks for a great guide. I’ve been trying to fix my dad’s laptop with not much success.

G60 – 441 US After a normal boot, the thing will run for about 2 minutes at which time the backlight goes off. It will erratically come on by opening and closing the lid. Color is good when the lamp is on. A no brainer I thought. Replace the inverter – which I did, using your great guide. NO change at all. On further investigation, I find that the screen will stay on forever if I boot to safe mode.

So, is it some sort of bad bios driver? Perhaps some thermal problem and the graphics chip draws less power in safe mode due to lower resolution?

I’m not sure if it’s worth the trouble to try to flash drivers if this is truly a hardware problem. Opening and closing the lid will switch the backlight on and off as reliably as can be (in safe mode). Other than the lid switch, what else will turn off the inverter?

Hello, About 4 days ago I spilled milk on my G60. I quickly turn it off, then tried to wipe off as much as possible. I then waited about 8 hours for it to dry but it didn’t turn on. Two days later it started to work again, but about 3 hours into it on the screen started to get dark. Over the next 10 minutes it gradually got darker and dark until it went totally black.

I am not sure what to replace here. I was thinking I should replace the screen or is there some other device that was ruined too that may have led to the screen to burn out. Any help would be appreciated.

Thank you, Jonathan Bush •. Jonathan Bush: I can’t be sure, but I think you need to replace the screen inverter.

Were there any dead pixels on the screen? If not it sounds like it isn’t lighting properly, which is not a problem with the screen, but the inverter. It could be both that have gone, but normally water damage will damage the inverter, not the screen. Think of it this way: You’re using your laptop in the rain, what’s going to break? Some contacts or the screen? The contacts in the case with the screen are the screen inverter, hence you need a new one. The screen is only a surface to should not be subjectable to water damage, only physical damage.

Regards, Jonathan. First off, this guide is great, so thank you! I used it to replace the screen inverter in my girlfriends G60, and that went fine and everything for a while. But then after a couple weeks, the screen starting flickering a lot, the image would even shift occasionally (like jump around like an old CRT with a bad signal), and it would emit a high-pitched noise while doing this.

Moving the screen around could get it to stop acting up, so I thought it was just a loose wire. Took it apart again, checked all wires, everything seemed fine, but problem persisted, and got worse and worse until now it’s no longer usable at all. Basically no light at all, plus the noise (which it didn’t make with the old, bad inverter). So is this likely another bad inverter, or could it be the backlight itself? I attempted to get access to the light so we could test it, but this guide doesn’t go that far and it seems very invasive, so not sure I want to try when I’m not sure that’s the problem. A new inverter is $15-20, a new screen is >$100, so don’t want to break what ain’t broke~ Sorry for the wall of text, but don’t know where else to ask!

sallie, i am stuck on step 4. My keyboard connector looks slightly different than the one pictured. I’m confused on whether the white clip stays put, or must stay connected to the keyboard cable.

The locking clip ALWAYS connected to the connector base. The keyboard cable jammed between the connector base and locking clip. When you open the connector, the clip must stay attached to the base. I’m not sure why you have a different connector.

I thought it would be the same for this laptop series. Be very careful with the connector. If you break it, the keyboard will not work. It shouldn’t be very difficult to unlock it, just work slowly.

It’s hard to tell what’s wrong.

A failing inverter board or backlight lamp wouldn’t cause the image flickering. When inverter or backlight fails, you just lose the screen light BUT the image shouldn’t jump, flicker, etc It’s possible the LCD screen itself is bad but it’s hard to tell without testing the laptop with another working screen. Hi, great guides on here. My wife has an 18 month old Compaq CQ60 (HP G60) which has just thrown up a problem. If the lid is opened further than about 1/3 the display cuts out although it still appears to be backlit.

It is occasionally possible to get the display working again by “flexing” the laptop in the area of the left hinge but the picture never stays on. I suspect that the display cable is damaged at the hinge point, what do you think?

Sadly, at 18 months old, the laptop is out of warranty by 6 months (aint it always the way!) – what’s a real shame is that she has really looked after it, if she’d been a little rougher with it there’s a good chance the cable may have “failed” within the warranty period. sharon, hi there i have used your guide to replace the screen which has gone fine i have fitted the new screen but i have no display i have checked all cables and they seem fine It’s hard to tell what went wrong but here are a few tips for troubleshooting the problem. Did you remove RAM modules while removing the display? If you did, make sure they are seated correctly. Make sure the video cable connected properly on both ends, on the motherboard and back of the LCD screen. Disconnect the video cable from the motherboard and test your laptop with an external monitor.

If external video works fine, your problem is somewhere inside the display panel. If there is no video on the external monitor, your problem is somewhere inside the laptop itself. Karen, Have HP G60 and just replaced the cracked LCD screen w/ new one, then screen goes dim. I replaced the inverter which also did not help (new screen still dim and can see with flashlight). Did the cracked LCD have light? If the cracked LCD screen had light but the new one goes dim, it’s possible the new LCD screen is defective.

Went to put old screen back in to see if a bad inverter i received and now the laptop will not turn on at all, even with AC power connected to wall. What could be going on? Make sure the video cable connected correctly. Unplug the laptop from AC adapter, remove the battery, wait for a few minutes. Now plug the battery and try turning it on again.

Kris Hood, Wonder if you can help. My laptop screen has gradually got worse and now it is red with one bright red line running down the side. Also, blues go white and whites are blues. Used to be at certain angles but it is all the time now. I followed your instructions just incase it was a loose connection but didnt improve.

First of all, test your laptop with an external monitor. If external image works fine and the problem appears only on the laptop screen, it’s either bad video cable or faulty LCD screen. You can disassemble the display and try moving the video cable while the laptop is turned on.

If moving the cable affects image on the laptop screen and it changes somehow, probably the video cable is bad. Try replacing the cable. If moving the video cable doesn’t affect image on the screen at all, probably it’s bad LCD screen. Try replacing the screen. Kris Hood, How would I take the display apart while the laptop is switched on? I thought about this as I believe it is a loose connection so not sure where to look. As it is ok at some angles thats what made me think it is loose.

It is fine on external monitor. I have another idea.

In this model there is a good part of the video cable running under the keyboard. You can try removing the keyboard bezel with keyboard as it shown in steps 1-6. You can skip removing memory, hard drive, wireless card. After the keyboard and bezel removed, you can try reconnecting the video cable shown in the step 8. Try moving the video harness while the laptop is on. Does it affect image on the screen at all? Sometimes the video harness gets damaged in the hinge area.

OK, I tried what you advised and it it seems its been pinched by the hinge by the looks of it. I say this only because nothing happens if I move or disturn the connector at the connection into the motherboard, but it goes on and off if I adjust or move it at the hinge part. Made it slightly worse in that all blacks are red now and sometimes a blank screen will appear and i have to dismantle it to adjust it again.

Any idea how much a new cable may cost and where to get it from? Thanks for the advice, very good website. I was asking if it’s strictly necessary to find out which is the LCD model number, as I saw, on some sites, that they didnt ask for it in the form to order a new LCD, but only the laptop model. The stuff I was talking about = the whole process of removing keyboard etc. It’s not important any more tho, I got as answer from the seller I asked to. Thanks the same Marco, is there a model of LCD i can buy which will surely fit to my laptop without having to do all this stuff? I have a Compaq CQ61-112 SL, and i was looking on some sites, like screentekinc.com, and they seem listing every possible model, without opening it.

What are you talking about??? Without having to do what stuff??? Marco, I was asking if it’s strictly necessary to find out which is the LCD model number, as I saw, on some sites, that they didnt ask for it in the form to order a new LCD, but only the laptop model. The best way to find a new compatible LCD screen is searching by the original screen model number. The model number printed on the original screen. Or you should be able find part number (screen model number) in the official service manual.

The stuff I was talking about = the whole process of removing keyboard etc. You cannot remove the screen bezel and replace the screen until you separate the display panel from the laptop base.

Yes, you have to go though all disassembly steps. I guess it’s possible to remove the bezel and replace the screen without removing the display panel, but there is a good chance to damage the cover doing that. First off nice instructions for removing the lcd very easy to follow looks like. I have a Compaq CQ-50 with a monitor issue.

My screen would go white at times and I would sometimes have to tap it to make it stop going white and working properly. Well now my screen has gone super dark. You can see that it is on and with the right light able to see what is on it very faintly. I have been searching online to figure out if I need to replace the lcd or if there is another repair I can do. Has my backlight gone out and if so is it something I can repair or will I have to replace the whole screen? One site was mentioning something about a switch possibly being stuck.

Allen, I have a Compaq CQ-50 with a monitor issue. My screen would go white at times and I would sometimes have to tap it to make it stop going white and working properly. Well now my screen has gone super dark. You can see that it is on and with the right light able to see what is on it very faintly. I have been searching online to figure out if I need to replace the lcd or if there is another repair I can do. It’s hard to tell what is failing.

One part of your description (when it goes completely white) sounds like the LCD screen failure. Another part (when it turns very dark) sounds more like the inverter board failure.

First, I would check connections between the video cable and motherboard, LCD screen, inverter board. Try reconnecting the cable and test the laptop again.

If it doesn’t help, I guess you’ll have to replace the LCD screen and maybe inverter board. IML Tech Says: It’s hard to tell what is failing. One part of your description (when it goes completely white) sounds like the LCD screen failure. Another part (when it turns very dark) sounds more like the inverter board failure.

First, I would check connections between the video cable and motherboard, LCD screen, inverter board. Try reconnecting the cable and test the laptop again. If it doesn’t help, I guess you’ll have to replace the LCD screen and maybe inverter board. Okay I will check all the connections and see if that changes any thing. So currently it is just dark almost totally black but I can see the log in screen etc.

That was what made me feel that the back light might be the issue. So if checking all the connections doesn’t fix the issue you are saying that the inverter may have gone bad causing the back light to not come on? Also as to the screen going white.

It would usually do that at boot up. Flicker in and out of white which usually would either stop or if I tapped the screen backing it would correct the issue.

Thank you for your advice and help. I have a CQ50 and the screen occasionally will flicker and scramble, with green lines that seem to follow color gradients. For instance if watching a video on the laptop, the green lines will follow the contours and shadows of an actors face. This seems to happen with wavering intensity, almost like a flame, where it flickers strongly and weakly. If I scroll to the bottom of this page, where the gray gradient is and the “popular posts” bar is, I see the flickering, especially around that diagonal line in the design.

If I scroll to the comments where it is mostly just white with black on the sides, I see no flickering. I know this sounds crazy, but it’s what I’m noticing. Do you have any suggestions? I’m not sure if it’s the screen or the inverter.

Allen, Okay I will check all the connections and see if that changes any thing. So currently it is just dark almost totally black but I can see the log in screen etc. That was what made me feel that the back light might be the issue.

So if checking all the connections doesn’t fix the issue you are saying that the inverter may have gone bad causing the back light to not come on? Yes, it does sound like backlight problem, but I cannot tell if this is just failed inverter. It’s either bad inverter causing the back light to not come on OR the backlight lamp inside the LCD screen is bad. Also as to the screen going white. It would usually do that at boot up. Flicker in and out of white which usually would either stop or if I tapped the screen backing it would correct the issue. This sounds more like LCD screen failure.

It’s possible that you have TWO issues: bad inverter AND failing LCD screen. It’s not very common when two components fail at the same time, but possible. I’ve seen it happening before. It’s hard to troubleshoot laptops like that without working spare parts. Thanks for the great guide! Apparently there is either a design or assembly flaw which causes the video cable to be “pinched” by the left hinge assembly causing the display to flicker and distort on two identical laptops I own.

It would clear up by moving the screen back and forth and finding the “correct” angle. Very annoying, but obviously a “mechanical” gripe.

I disassembled the laptop per your guide and found the problem. Judicious and minimal use of a Dremel tool to enlarge the opening on the left side of the display cover for the video cable access fixed the problem. I was able to figure out to lift the tiny black hold-down on the switch board cable for removal (only thing the guide did not spell out). My PC Repair Shop Owner friend did not want to attempt the fix, I believe for fear of disappointing me either in the cost of repair or the potential inability to repair the problem. Of course, my 8 years of avionics tech.

Experience from ’84 to ’92 helped with the process. Thanks again! I used these instructions and found them very easy to follow.

I have the HP G70 120EA and the left hand bracket broke away from the lid. I purchased another lid and everything works well now I do not have a floppy screen any more and was very capable of changing it on my own There is a risk of getting the leads caught on the left hand side by the hinge when putting it back together, but I found if you are patient and do not try to rush it then it does go back together quite easy. Every screw went back where it came out also as I marked everyone on an A4 sheet of paper with a diagram If I can change it and ‘I’m a girl’ I am sure anyone can •. Thanks for the perfect description.

A friend of mine has trouble with this laptop, shop conclusion screen is broken. I’ve been fidling around with it and finaly I got it started for one time so screen is not broken, I made a quick backup of all foto’s. So small succes. I was not able to get it started again later on, also not with external screen Now there are some items I want to check to get it running. So I’m searching for the switch that indicates if the monitor is open or close, I think maybe the motherboard thinks that the screen is closed.

Thanks in advance. maarten, I’ve been fidling around with it and finaly I got it started for one time so screen is not broken, I made a quick backup of all foto’s. So small succes. I was not able to get it started again later on, also not with external screen This could be memory failure. Try removing memory modules one by one and test the laptop with each module individually. Now there are some items I want to check to get it running. So I’m searching for the switch that indicates if the monitor is open or close, I think maybe the motherboard thinks that the screen is closed.

I believe this laptop has a magnetic switch. A small magnet inside the display panel activates the switch located inside the laptop case.

I doubt that your problem is related to the switch, it’s not a common failure. I have a G60 and there is a crack in the monitor/screen. I spoke with HP and they want to replace the entire monitor, which is almost the cost of a new computer. How can I tell if it just needs a new LCD screen rather than a whole new monitor. The cracked screen has caused the ink to spread over half the screennone is leaking at this time. Also, I believe that there is also a backlight lamp that may be outa while ago the screen got a little darker in one areaare there lamps that can be replaced while screen is apart?

Betsy, I have a G60 and there is a crack in the monitor/screen. I spoke with HP and they want to replace the entire monitor, which is almost the cost of a new computer. That’s just how HP works. They don’t replace LCD screens, they replace the entire display assembly.

Sounds like you have to replace just the LCD screen as I replaced in this guide. Don’t worry about the backlight, it’s a part of the new screen. moe, my hp g50 screen light is not workin. I can see my screen display but it like my screenbacklight is not workin. Do you know wat caused dis? If I understand correctly, the laptop still works but the image on the screen is very dim. Most likely it’s either bad inverter board or failed backlight lamp inside the screen.

If you have to guess, try replacing the inverter board first. If it doesn’t help, replace the LCD screen. There is a chance of bad motherboard, video cable, but it’s not likely with a problem description like yours. Maarten, I found the magnet inside the screen casing.

I think the sensor is between power and wireless lan button? Close the display panel and see where the magnet “touches” the laptop base. The switch is somewhere around that area under the cover.

Again, I don’t think that magnetic close switch causing the problem. I already tried other ram memory, and today I put in the memory of my own laptop. Again no succes. Withouth the memory the pc gives 4 beeps. With the memory no beeps. I’m running out of options. As a last resort, you can try minimizing the laptop to barebone system.

Remove all parts and leave just the motherboard, CPU with heatsink and memory. Test barebone system with an external monitor. If still no image, probably the motherboard is bad.

robert downey, hp g70. When i close lid the casing at back is sort of forced apart only a few mm but still obviously not right. If any one knows or has had this issue please reply, im willing to follow these instructions but im not sure if i need to follow the whole process as lcd screen is working perfectly ans is just the case? Hinges that i think are at fault.

Sounds like broken hinge. You’ll have to disassemble the laptop and take a closer look but I’m pretty sure it’s hinge related problem. I am working on an HP G60 where the right bottom corner of screen had come apart/separated.

The laptop was working fine before i worked on it, except for the separated screen. I went through all your steps above and now the computer will not turn on/respond at all. I agree with the comment above that these instructions were helpful, but you need to show a close up view of the switch board cable connector and how it goes together. I was not exactly sure how this connector went back together and I believe it could be the reason why it will not turn on. First time I’ve had to replace a laptop screen.

I’m working with a CQ62-215DX. The laptop had been dropped and screed cracked.

I’ve went through all the steps which were very close to your instructions. Just additional screws in a couple of places.

When the battery is installed, the screen lights up with a dim white back light. When powered on, it boots normally and works properly with areas that should be black completely black and no bleed over from the back-light. Screen has no issues until you shut it down. The back-light seems to never completely power off. It goes back to a dim white light. Never mind.

I’ve got it working. The replacement screen had a 5″ ribbon connected to the video port on it. I guess it was there in case the video cable comes from the opposite hinge. I removed this ribbon and connected the video cable directly to the screen. Now the screen is working 100%.

My screen is permanently very dim. It must be attached to another monitor just to see the display. Is there an easy fix or will the backlight or entire screen have to go? Most likely it’s either bad inverter board or failed backlight lamp inside the LCD screen. You can try replacing the inverter board as it shown in this tutorial.

Inverter shown in the step 13. If replacing inverter doesn’t help, most likely you’ll have to replace the screen. Also, there is a chance of bad video cable or even motherboard problem but it’s not very common. princejoygerona, I had a hp G60 suddenly LCD problem which is the screen display divided into two parts: on the top it was ok but lower part is black and white rainbow tiny strips. Please help me identifying what causes this problem exactly and what to do to fix it?

Test laptop with an external monitor. If external image works fine (I think it is), the problem is somewhere inside the display panel. Most likely it’s either bad cable connection or failed LCD screen. Try reconnecting the video cable on both ends. If reconnecting the cable doesn’t help, try replacing the LCD screen.

I think this is LCD screen failure. When I disconnected the switch board cable from the motherboard, I also pulled off the small black piece that I assume was used to keep pressure on the switch. The black piece seems doesn’t stay put any longer, however, if I keep pressure on that piece, the HP CQ50 laptop turns on and runs fine.

Guess I can’t hold my finger on forever so I would like to ask if you have any suggestions. I have already tried placing a small amount of glue from a hot glue gun on it and that didn’t work. Just so you know I also attempted putting wood to apply pressure and that didn’t work either. I ended up taking the glue and wood off and again if I apply direct pressure, it turns on and operates just fine.

Any suggestions would be appreciated. It’s not the end of the world, but if anyone has a suggestion, I’d greatly appreciate it. Ron Simmons •. Ron, I just replaced my screen and I ran into the same issue that you described. In step 5, the small black clip that applies the pressure to the blue ribbon cable wasn’t clipping in. The problem was that I was installing the clip upside down – VERY hard to tell since it sits in the slot perfectly (it just doesn’t clip in).

There is a similar clip with a blue ribbon cable toward the bottom of the keyboard opening that I had to study to understand how the black clip is supposed to snap into the white enclosure. This clip/cable is visible in the photo for step 5. By the way, FANTASTIC TUTORIAL!!! I had to take apart my hp G70 111EM laptop because the hinges eventually sliced through the video cable and I also needed to replace the fan, but when I was putting the laptop back together a black hinge connector fell off On the keyboard cover, you have the power n wireless button. The black clip that holds the cable in on the motherboard has fell off n now my laptop wont switch back on, would this be the problem. Would i need to replace the motherboard or can i just get a new clip attached so it will hold the cable in?

Would i need to replace the motherboard or can i just get a new clip attached so it will hold the cable in? Very useful article, thanks! One improvement I would like to mention is on step 8. There are 2 ways to remove small connectors: Pull backwards on the wires or lever/pry the connector off of the receptacle. I found out that prying the 4 pin webcam connector results in a busted connector.

Would you add “by pulling backwards on the wires” to that step? The rule of thumbe I’ve always used is that if the connector has multiple input wires that consist of very thin cable guages, you should pry. Didn’t work here. I’ve send in a donation. Thanks again!

Peter Huss, My problem is that the screen is black (after beeing dropped to the floor) and if I press hard on top of the screen connector, the screen flickers (sometimes) and I see what is on it. I suspect a loose connector somewhere. Any ideas to help? Is there another connector of sorts under the motherboard? There is no other connection under the motherboard. The video cable connector located on the top side of the motherboard.

Have you tried reseating LCD cable connector on the motherboard? It’s possible you have loose connection INSIDE the display panel. Maybe connection on the inverter board or LCD screen. here’s my guide to have a complete bios reset: Question How can I reset CMOS / BIOS settings? Answer If your computer is having issues booting, has errors during boot, after adding hardware is running into issues, or you’re having other abnormal system behaviors that cannot be resolved though any other method it may be necessary to reset the CMOS settings or load the default or fail-safe defaults as explained below. Load / Reset defaults Enter CMOS setup.

In CMOS setup look for an option to reset the CMOS values to the default setting or an option to load the fail-safe defaults. With many CMOS setup screens there will be a function key to do this; for example, the F5, F6, F9, F11, or F12 key like shown in the picture to the right. Other setups may actually list an option that you can arrow over to using the arrow keys and press Enter. When found and selected you’ll likely be asked if you’re sure you wish to load the defaults press Y for yes or arrow to the yes option.

Once the default values have been set make sure to Save and Exit and not just exit. Reset Configuration Data In addition to restoring the system defaults if you’ve recently added new hardware or resetting the default values did not help resolve your boot issues you may also want to reset the configuration data. Note: Not all CMOS setup screens will have this feature.

Under advanced If you’re working on a computer with a Phoenix BIOS that has Main – Advanced – Security –. Across the top of the screen you can get to this setting by using the right arrow to move over to Advanced and under Advanced arrow down to Reset Configuration Data and changing the value from Disabled or No to Enabled or Yes. Once the above has been done press the F10 key and save and exit CMOS setup. In PnP/PCI Configurations If you’re working with a Phoenix BIOS that has several different options and one of them is PnP/PCI Configuration move the cursor down to this option and press Enter. Within the PnP/PCI Configurations change the Reset Configuration Data from Disabled to Enabled. Once the above has been done press the F10 key and save and exit CMOS setup.

Hard reset the CMOS When inside your computer make sure you’re aware of ESD and all it’s potential dangers. If the above steps do not reset the CMOS settings we suggest removing the CMOS battery for 5 minutes causing the computer to forget all settings. Removing the CMOS battery like the one shown in the picture to the right will cause the system to loose all CMOS settings including the password. To do this locate and remove the CMOS battery on the motherboard for at least five-minutes. After this has been done put the battery back into the computer and turn it back on. If your computer does not have a CMOS battery or you’re unable to find it you’ll need to do a hard reset on the CMOS using a jumper or dipswitch on the motherboard. Information on finding these can be found through your computer or motherboard documentation.

hello, im trying 2 fix a presario cq60-300 the screen is black (not even dim). Display works through external vga i have replaced the inverter i have replaced the screen (w / backlight) still getting no kind of display on the lcd. I thought it mite b a lid switch type problem but i cant seem to find 1 anywhere. Im curious as to what the magnet does that is taped inside the screens front plastic bezel. When put back together it appears to line up with the inverter.is this something like a lid switch?!! I think it could also possibly be a cable issue.iv tried reinserting them all about 400times tho so maybe it has broke inside.i would hate to order a cable aswell only to find out that didnt work as i have already spent £70 on an inverter and new screen (which i dont think i can return now its been unoppened ) thanks for any reply thanks in advance as •.

I used this guide to replace the webcam in my daughter’s G60. Only needed to go through Step 13 to do so. One difference, though, is that there were 2 webcam wires running to the motherboard connector shown in Step 8, one of which went under the M/B, so I left that connector connected, and laid the upper half of the laptop on top of the lower half while I removed the screen bezel.

The webcam is held in the upper frame with double-stick tape which is VERY sticky and hard to unpeel. It took a lot of coaxing but I got it out and put in the replacement ($11 used from eBay vendor). I reversed the dis-assembly steps and the laptop went back together OK with no extra parts! Before I started, I used Device Manager to uninstall the webcam. After re-assembly I re-started the laptop, it detected new hardware (the webcam), installed the webcam with resident drivers, and “voila” the webcam worked! I never would have attempted this replacement without this excellent guide. Thanks for this post.

I, (unfortunately ), want to ask for help as well. My Presario CQ50 fell onto the ground today and the backlight has broken. That is, the display itself seems alright (I can see the image under the direct strong light) and I’m currently writing from this laptop via the external monitor, but I don’t know how to fix the backlight and how much would it cost.

I’ve found something about the screen inverter here though as I’m really not a technician I have no idea how it works. I tried to dismantle the laptop and reconnect all the screen cables as shown on this page but to no avail. It still works (at least I didn’t screw up) but the backlight is still off as well. Could you, please, help me? As I’m a student with not much money to spend, I really hate the idea of importing a new screen (and would it really help?) or visiting the service center which is VERY expensive in my country. Thank you very much! Denis, My Presario CQ50 fell onto the ground today and the backlight has broken.

Most likely the backlight lamp is damaged. Would it be enough to buy a new CCFL backlight tube and replace it? Yes, it would be enough but the backlight lamp mounted INSIDE the LCD screen and very difficult to replace.

john, i followed these steps and i can make out the picture on the screen but the back light wont turn on, i checked all the cables replaced the inverter and even tested the back light on another laptop but it still wont turn on with my hp g60 235dx If we assume that your new inverter is good and backlight lamp works properly (as you tested it with another laptop), your problem could be related to one of the following: 1. Bad connection between the video cable and motherboard. Bad connection between the video cable and LCD screen or inverter board. I said you checked all cables but make sure to check all connections. Try reseating them. Bad video cable. Motherboard failure.

It might be the lid switch but i dont know where it is located specifically I don’t remember off the top of my head, but I believe this laptop has a magnetic lid close switch – a small piece of magnet located somewhere under the screen bezel activates a switch located somewhere under the palm rest. I cannot tell you the location of this switch. Search for a small magnet under the screen bezel. It will give you the idea where the switch is located. Roy Musall, I have a reburb Compaq CQ50, which worked fine for awhile, but now the screen does funny things.

It will get lines that wiggle, but still will be viewable, but also anything that is white will turn pink. I believe its a bad screen. Any ideas How about video on the external monitor? Is it working fine? If external video is fine and the problem appears only on the laptop screen, it could be one of the following: 1.

Poor connection between one of the video cable connector and motherboard/LCD screen. Try reconnecting the video cable on both ends. Bad video cable.

Try replacing the cable. LCD screen failure. Jon K, I cracked my screen 6 months ago, but using the VGA or HDMI output onto either my TV or another PC doesn’t work, and did before I broke it. Will changing the display as per this guide fix the problem?

Can you get any image on the cracked screen? What if you disconnect video cable from the motherboard and try using the laptop with external TV or monitor after that. Will it work when LCD screen cable disconnected from the motherboard?

If not, most likely there is another problem with the laptop. Try reseating memory modules. It’s possible one of the modules popped out of the slot when you dropped the laptop. If the laptop will start working with external TV or PC monitor after you reseated memory modules, probably it’s save to replace the cracked screen too. Andy, What are the cables coming out from the left hinge?

My screen isnt showing any picture at all but the laptop is still turning on normally. So i assume the problem is in the cable especially the one on the left that goes long to the bottom or the thick black one.

Would you help me identify them and advice which parts i have to buy if i want to replacr all of this cables. The left cable that goes long to the bottom is (I believe) the microphone cable. This one is not related to your problem, that’s for sure. Harlequin Rapidshare Library here. Two other black thin cables running though left and right hinges are wireless card antenna cables. Also not related to your problem. The think black one is the VIDEO cable.

This one transfers data signal to the LCD screen and voltage to the inverter board. Is your screen completely black and blank? Take a closer look at the screen. Does it have a very faint image? Does your screen change color from completely black to light black/gray when you turn on the laptop.

I’m just trying to figure out if your problem is related to the LCD screen or video cable. By the way, try reconnecting the thick black cable. Maybe it’s just not making good connection with the motherboard. hi, my son dropped my hp g61 laptop, and the screen went black, however you could see a very faint image in the back ground! The screws on the screen hing somehow worked them self loose, and my wife kept using it but with a external screen, however it was getting harder to close, when both hinges had come off i took of the cover tried the laptop without the external screen and i can get a picture at all, do you think it has damaged the inverter, and screen? Still works perfect on an external screen cheers mark •.

mark, my son dropped my hp g61 laptop, and the screen went black, however you could see a very faint image in the back ground If the screen backlight stopped working after the laptop was dropped, most likely it happened because the backlight lamp (located inside the screen) was damaged. If that’s the case, you’ll have to replace the screen.

Just in case, you can try reconnecting the inverter and screen cables before replacing the screen but I think chances to fix the laptop by reseating connectors are very low. Hi, this is awesome, very helpful instructions. I had a damaged lcd screen for presario cq-60 laptop. Everything went fine and I can see the monitor working fine now. I have only one issue to resolve. The switch board cable to the motherboard is not connected permanently, I just tried by holding with my hands everything works.

But it is loose and the moment I remove my hands it doesn’t work. I have removed a black strip which was still there in the mother board pin and I am not able to put it back and i think thats what holds the connector tight. Appreciate any help in this regard. @ Suresh, I have removed a black strip which was still there in the mother board pin and I am not able to put it back and i think thats what holds the connector tight. Sounds like you damaged the connector because the locking clip should stay attached to the connector base. Here’s what you can try to fix the problem.

I assume you still have the broken piece. Insert the cable into the connector the way it should be.

Place the broken pieces back into the connector the way it should be. Secure this connection with sticky tape. Here’s another trick you can try. I don’t have pictures but I’ll try to explain. I used this method on one of my laptops and it works great.

Insert the cable into the connector. Now you have to find a very thin piece of plastic (probably 0.25-0.5 millimeter) and insert it into the connector above the cable, there should be a gap between the cable and connector. This piece of plastic will apply pressure on the cable and it should work after that.

@ Joe, Me again with the white screen and no signal to external. Could it think the lid is closed for some reason? I don’t think your problem is related to the lid close switch. In the previous comment you mentioned that your laptop screen is gray white.

It means the backlight still works properly. When the lid switch activated (display closed), it turns off the backlight. In your case the backlight is still on, so the lid close switch is fine. If you disconnected the video cable from the motherboard but still cannot get any image on the external monitor, i think this is motherboard related failure. @ Alistair, I have a Compaq Presario CQ50 with a second monitor. I recently found the bottom half of the screen on my laptop has developed horizontal lines which obscure/distort the image.

I’ve tried restarting the machine, but that doesn’t cure it. Interestingly, the picture on the second screen is fine. Do you have any ideas what the problem is before I set about replacing the screen? Most likely this is failed LCD screen.

Just in case, before you replaced the screen, check connection between the video cable and motherboard. Make sure the video cable connected properly. If reconnecting the video cable doesn’t help and the bottom part of the screen still distorted, I guess you’ll have to replace the laptop screen. @ Kevin, I did all the steps and not the laptop will not power on. What did I do wrong?

I installed the new display and nothing, no power. I even reinstalled the old cracked display and nothing.

It powered up fine before I did the swap. The charging light glows at the A/C charger but no computer power. Any help would be appreciated! Did you remove the top cover assembly in order to swap the LCD screen? Take a look at the power button cable shown in the step 5.

It’s possible you forgot to connect the cable and the laptop will not turn on because of that. very good instruction. My screen wasn’t the problem, but my cable was worn and shorted through, which seems to be a widespread problem (white lined screen). With use, especially by my kids, one of the hinges loosened over time, and that caused wear on the screen wiring harness that runs through the hinge.

Your instructions were great for replacing the wiring harness. For anyone doing this, or otherwise opening up a laptop, you need to work very slowly and carefully with the connectors and snap-in tabs. If you break a connector, you’re in worse shape than when you started. I had trouble with flickering and followed these instructions. You should add a little footnote about the trickiness of getting the power button/wireless connector back on. You really have to slide the black clip under the metal connections after putting the conducting tape in Besides that, I owe you a huge thanks.

This was incredibly helpful and, although I didn’t go through with the replacement since I was just checking connections, with moving the wires around it appears to have solved the problem. Couldn’t have done it without your help. Thanks so much for the tutorial! I had the same problem as many people here. My screen had blue and pink horizontal lines, and sometimes I would get a pink all over the screen, or just a complete grey, depending on how far the lid was open. I ordered a replacement video cable from HP and, using all but step 20, I (think) I successfully fixed the problem.

It also seems to have cured an issue I was having with my webcam only working when the lid was all the way open. The only additions I have to your directions is that step 5 involves gently popping up the black part so it sweeps toward the screen in order to remove the cable. I also basically broke the connector from the video cable to the left side of the inverter trying to remove it.

I have no good suggestions for how to do this other than tons of patience and tweezers. Also, take copious pictures with a digital camera as you go, particularly in the area around the hinges, so you can retrace the path of the wiring. Thanks again! You are the man. My daughters cq50 had the flickering screen issue.

I followed your excellent instructions and found the issue. Where the screen wires make the next to the last turn before heading into the hinge area they pass under metal tabs. On both sides at that tab area they had worn slightly and were touching the tabs and shorting. I used some electrical tape and voila!!! Thanks so much for taking the time to provide such a thorough, well documented tutorial. I had the flickering problem for a long time and today I sat down and spent 2 hours meddling around.

I just rearranged the wires and the problem was fixed! One thing though, I destroyed the webcam cable white thing, because it wouldn’t come out. I ended up using a screwdriver and pry it. When I put it back though, it still works. I had to use electrical tape to fix it. Thanks to those comments below about the little details he forgot to add! Compaq Presario CQ50 Windows 7 Ultimate x32 •.

I found a replacement LCD Cable on ebay for $15. Repair went smoothly, and laptop is working fine. Be *very* careful with the small cable that connects the power button to the main board (step 5). I broke the latch, and had to use glue and tape to hold it in place. It would also be a good idea to mark the edge of the lcd cable and webcam cable to make sure you position them correctly when replacing. The design of the left hing where the lcd cable passes through is flawed. I added some foam padding on mine to try to prevent the problem from recurring.

@ chris, i broke a hinge, so i took my screen apart, put it back together and it wont light up anymore, so i bought a replacement inverter, still no backlight, then i hooked up a brand new baclight to my brand new inverter,with a brand new harness, still no baclight, u can see a the screen works, when i use a flashlight, and the external monitor works also, i just cant get it to light up, any guesses? Maybe you accidentally pulled the video cable connector from the motherboard? Try reseating it. @ Phil, For about a month, my screen was having trouble, like a fluorescent light (flashing). Yesterday, I powered on, and just after logging in to windows, screen went black. After cleanning it, I could see my desktop, but extremely black.

There is no light. This could be one of the following: 1. Bad connection between the video cable and screen inverter. You can try reseating connections. Failed inverter board. Try replacing the inverter.

Failed backlight lamp inside the screen. Try replacing the screen.

Possible but not likely failed video cable. @ kris, I was able to open the LCD and tried to reset video cable connections.

But when I put it back, I am still getting a blank white screen display for few seconds and it turns black again. Could you please tell me if this is due to bad video cable or invertor? External monitor display works fine. This problem is not related to the inverter board. You can see the white screen, it means the screen lights up, it means inverter/backlight work properly. Replacing inverter will not change anything. Most likely it’s either failed LCD screen or bad video cable.

If you have to guess, try replacing the LCD screen first. Also, this could be motherboard related issue, maybe defective video connector on the motherboard but it’s not very common type of failure.

@ Phil, Is it an inverter, lcd screen, backlight or video cable problem? Heres a video that might help: First of all, I don’t think this is inverter problem. Second, before you jump to any conclusion, test your laptop with an external monitor. If external video works fine and the problem appears only on the laptop screen, this could be one of the following: 1.

Bad connection between the video cable and motherboard or LCD screen. Try reseating the video cable on both ends.

Failing video cable. Try replacing the cable. Failing LCD screen. Replace the screen. It’s hard to troubleshoot this problem without spare parts. If you don’t have them, you’ll have to guess. By the way, it the same problem appears on the external monitor too, this could be motherboard failure, probably bad video card.

@ Phil, So It would be either a failed video cable or a failed lcd screen. Dont you think theres a chance the problem could be a failed backlight? I don’t think this is backlight or inverter related failure. When backlight/inverter fails, the screen goes dark BUT the image on the screen doesn’t jump up and down like in your case. I’m pretty sure it’s not the backlight related problem. Here’s something to try.

Take apart the display panel but do not disconnect video cable from the screen. Turn on the laptop and try moving the cable while the laptop is running. If moving the cable affects image, probably you have bad video cable.

Maybe there is short somewhere inside the cable. If that’s the case, replace the cable. If moving the video cable doesn’t affect image on the screen at all and it fails randomly. Probably there is something wrong with the screen. Hi IML Tech, Your instructions for accessing the LCD Display were very clear and useful although the model I have is a HP G70 120EA. The display would go of or wonky depending on the angle of the lid. This seemed to indicate a faulty Video cable or bad connection.

After stripping the laptop down I checked the video cable connections and all looked OK. I decided to replace the cable anyway. This I did and rebuilt the laptop. I did notice that the original cable had a kink in it just where it crosses over from main chassis to display.

I also noticed that after installing the new cable this was also getting twisted and kinked with movement of the lid.Seems like a poor design. After rebuilding it I get the power light on and nothing else. The wireless light no longer changes from red to blue. I can hear the drive and fan running and that’s it. @ John Wright, The display would go of or wonky depending on the angle of the lid.

This seemed to indicate a faulty Video cable or bad connection. This is correct. Most likely bad cable. After rebuilding it I get the power light on and nothing else. I can hear the drive and fan running and that’s it. Maybe not properly seated memory module? Check internal connections.

It’s possible some cables connected incorrectly. Really cannot tell what’s going on without looking at the laptop. The wireless light no longer changes from red to blue. I believe this light turns on only when Windows OS loaded. Frank, I have done exactly what you have on your website,except that while the laptop in uncovered the power comes on, but when I reassemble it does not power on. I have tried this several times with the same result.

So, the laptop power up when disassembled but fails to power up when assembled? Sounds like some kind of grounding issue.

Maybe the top cover is touches the motherboard somehow? Make sure all screws installed correctly.

If you use a long screw in a short whole, it might touch the motherboard. This is just a guess. Cannot tell what’s going on without testing the laptop. @ Mike B, I have the G50 and the same problem as comment 436 John Wright.

Screen goes crazy depending on angle of lid. I’m sure it is a cable problem. Is there just one possible cable and how/where can I find a correct replacement? You can find a new replacement video cable for HP G50 laptop on eBay.

It looks like there are video cable with different part numbers. Are they interchangeable? I don’t know. Probably yes.

The best way would be searching for the same part numbers as on your original cable but it requires laptop disassembly. This tutorial was great, but I stopped at Step 5 because I had no idea how to remove the switch board cable from the motherboard. There was no close up photo with instructions on how the cable comes out. Not being familiar with these parts, I was afraid to proceed. Step 4 clearly shows how you move the plastic piece towards the monitor to remove the- cable but Step 5 is not very clear.

Tried to find a website which explained those types of cables with no luck. Don’t even know what that plastic piece is called.

@Mary There are mainly two types of ZIF connectors for laptops, the keyboard ribbon cables are generally locked with the sliding style connector. The smaller ones generally tend to be a flip style of ribbon connector lock. You can usually tell if there are small tabs on the side then it’s a slide style lock. Otherwise it’s a flip style. You can test this out by using a small amount of force lifting up on the side where the ribbon cable is inserted.

If it’s the flip style it will pop up easily releasing the ribbon cable. I’ve noticed that with HP’s and Compaq laptops 2008 or earlier the only sliding style lock is the keyboard connector, all others tend to be the flip style locks. Hope this helps. @ Mark Turrill, My compaq cg60 suffered black screen with faint images. Ordered an inverter board and replaced it with your excellent instructions.

If I boot with battery power only screen lights and everything looks fine, but when I plug in ac adapter, screen gets brighter as usual but after a couple seconds turns black. Rebooting produces same results. Could my new inverter be defective? It’s hard to tell without testing the laptop with a known good inverter. I think your problem could be related to one of the following: – your new inverter is defective. I would try replacing it first.

– the backlight inside the screen is failing. Great information, but I have a question for you My laptop screen was a little loose at the hinges and the screen would kinda flicker when I opened it. Yesterday, smoke came out of the left side where the screens folds up/down. Needless to say, the screen is just white now. I would like try and fix it. Would I need to replace the inverter and screen?

I was wondering if the wires (like those in step 11) that hook to the inverter, will come with a new screen if I buy one? I hope I didn’t confuse you not really sure about all of the parts involved.

Can anyone tell me what the part number is for the video cable for the HP G60? I’m looking to purchase this part on ebay so I can replace the video cable using this tutorial. Called HP and would you believe they would not give me the part number? Thanks for any help. Also does anyone have any tips for Step 6 – Removing the keyboard cover? Any tricks to get it to come off easily? I got one section disconnected but it seemed so fragile, I wasn’t sure where or how to aply the pressure to remove it.

@ Leah, My laptop screen was a little loose at the hinges and the screen would kinda flicker when I opened it. Yesterday, smoke came out of the left side where the screens folds up/down. Needless to say, the screen is just white now. I would like try and fix it.

Would I need to replace the inverter and screen? I think this could be video cable failure. It’s running though the left hinge. Take apart the display panel and take closer look at the video harness. Can you see burning marks? Try replacing the cable first.

The screen remains just white because it’s not getting any data signal from the motherboard. Most likely it happens because the video cable failed.

mary, Can anyone tell me what the part number is for the video cable for the HP G60? I’m looking to purchase this part on ebay so I can replace the video cable using this tutorial.

Called HP and would you believe they would not give me the part number? According to the laptop service manual (I published links at the end of the guide), the LCD cable part number is 496841-001. Also does anyone have any tips for Step 6 – Removing the keyboard cover? Any tricks to get it to come off easily? I got one section disconnected but it seemed so fragile, I wasn’t sure where or how to aply the pressure to remove it. After all screw are removed slide it towards the LCD screen.

Then lift up and remove. Thanks for such a great information. Can you please help me figure out what is the issue with my HP G70 laptop? And what need to be changes /replaced to fix it? Here is the situation. 1) The screen flickers violently.

And shows Red Pink and white lines on the screen. I have to adjust manually. 2) The Lid (Top Screen assembly) is got loose. And it wobbles badly. 3) The display bezel is torn up A) if we look from the back of the laptop, the entire bezel is separated in two parts. B) if we look from the sides, the bezel is separated of the screen from the bottom of the screen on both the sides. I kindly request you that please help me figure out that what should be done to fix these all?

Do i have to replace The screen bezel or The screen inverter board or Left & Right hinges or Video Cable connector or the entire screen.??? I will highly appreciate your help. Thanks in advance. @ Ashish, The screen flickers violently. And shows Red Pink and white lines on the screen. I have to adjust manually.

Can you adjust the screen (find the right position) and get the image back to normal? If yes, this could be either faulty video cable or bad LCD screen. Do i have to replace The screen bezel or The screen inverter board or Left & Right hinges or Video Cable connector or the entire screen.??? Cannot tell you what to replace without looking at the laptop. You’ll have to identify which parts are broken. @ IML Tech (@ Ashish, The screen flickers violently.

And shows Red Pink and white lines on the screen. I have to adjust manually. Can you adjust the screen (find the right position) and get the image back to normal? If yes, this could be either faulty video cable or bad LCD screen.) First of all thank you so much for the quick reply. Yes, if i adjust the screen and find the right position then the image comes back to normal.

And for that Bezel i have found out that it has almost separated it 2 parts from the two bottom hinge point. So should changing of it should be okay? Or do i need to change the video cable? I am not able to figure that out so please help me determine it.

@ Ashish, Yes, if i adjust the screen and find the right position then the image comes back to normal. And for that Bezel i have found out that it has almost separated it 2 parts from the two bottom hinge point. So should changing of it should be okay?

Or do i need to change the video cable? How changing the bezel can fix possible video cable failure??? Try replacing the video cable first. Make sure it fixes the problem. If not, most likely it’s bad LCD screen.

After the video problem fixed, determine which parts are broken and replace them. I cannot help you without looking at the laptop. Hi, I cut and pasted our original conversation below so you would know what I was referring to. I ordered a video cable and installed it and when I turned it on it worked (I have a picture now), but it is split into 4 screens could it maybe be the wrong video cable??

Thank you for your time. You have been a lot of help. @ Leah, My laptop screen was a little loose at the hinges and the screen would kinda flicker when I opened it. Yesterday, smoke came out of the left side where the screens folds up/down.

Can you see burning marks? Try replacing the cable first. The screen remains just white because it’s not getting any data signal from the motherboard. Most likely it happens because the video cable failed. I am having a similar problem as Willem.

In my case, the light on my Compaq CQ50-142US keeps going out intermittently. I can see the display, but there is no light behind it. After a second or two, the light comes back on. Am I correct in assuming that it is the backlight, or might it also be the inverter? I have taken the laptop apart before to get to the screws in the hinge, so I am comfortable enough doing that, thanks to this tutorial.

The backlight bulb itself is only about $5-10, but the repair manual only mentions replacing the whole LCD setup and I don’t see the bulb on this page. Is this something that I can do myself? Thank you sooooo much for the clear and concise tutorial and photos!! A bit of advice and waring to ALL. Be VERY careful with all connectors on PC boards!

Look carefully to see if and how the cable is locked in place. Don’t assume that the cable just plugs in! AS was mentioned with the keyboard cable @ the motherboard, CAREFULLY slide the white retainer clip forward a small amount. Best to slide BOTH ends simultaneously so as not to bend/distort the clip. Make sure that you unplug the power button cable, but I’ve found that the best advice is: DON’T REMOVE CABLES UNECCESARILY!

If you can get to something without removing a cable, DO SO, just BE CAREFUL! Thank you again and best of luck to all! @ Kym, Ok I did all this and installed my new screen but now everything runs upside down. I went in and switched the orientation in my control panel by 180 degrees which is all fine and dandy except that none of my games run right side up and I can’t seem to get them to switch with ctrl alt and the arrow keys. Any ideas anyone? I have no idea what’s going on.

Never seen something like that. Does the image appear upside down as soon as you turn on the laptop?

The manufacture logo appears upside down too? @ Deb, Lost the back light on g70 HP. Plugged into old monitor, everything else is just fine. Does this problem require changing out the whole screen as described here?

Most likely it’s either bad inverter board (shown in the step 16) or failed backlight lamp inside the LCD screen. First, I would try replacing the inverter. It’s cheap and relatively easy to replace. If this doesn’t help, replace the screen.

Also, this could be failed video cable or even motherboard issue but it’s not likely. Hopefully a new inverter will fix your problem. I have a HP G70-460US. My laptop screen is working but i have to open close the screen multiple times to get it to be able to see a picture. I was thinking of just getting rid of the screen and connecting a monitor – use the laptop as a keyboard, touchpad and desktop in one. I connected a monitor to it. Monitor shows a picture only when the laptop boots into windows.

I tried the F4, Fn F4 but the ext monitor won’t display bios booting. Is my video card faulty?

Is there any other way? @ Pee Kay, I have a HP G70-460US. My laptop screen is working but i have to open close the screen multiple times to get it to be able to see a picture.

Yeah, I’ve seen it happening before. Some laptops can display image on the external ONLY after Windows OS booted completely. Most likely you can switch to external right on startup if you disconnect the laptop screen cable from the motherboard. In this case the laptop will not see the internal screen on startup and will switch to external right away. You should be able to pull the video cable from the connector after you remove the keyboard. I had to deal with a HP G60 laptop that started with a fault of a flickering screen when the lid was moved. Eventually sparks started coming out of the screen hinge part that connects to the rest of the laptop.

I found that the graphics ribbon cable that goes from an edge connector on the left side of the laptop – through the hing and to the LCD screen assembly itself had its individual wires short circuit against each other through melted wire insulation. I replaced the graphics ribbon cable with a 2nd hand one from ebay and the display, so far, is working again.

I had the back screen flickering of death. I got a new video cable and inverter and replaced them per the instructions.

However, now the screen goes from being constantly lit to still turniong off after a few seconds of the lid being opened. However, now I have all sorts of blue and white (currently, they were grey/black earlier) running mostly vertical on the screen. I can see the normal desktop when I attach an external monitor but the laptop screen remains this vertrical blue/white stripe of death. My guess is the cable isnt fully connected?

Or dust got into the screen? Another issue is that there’s a black burnot spot that is growing in the right lower corner behind where the inverter cables go behind the screen. This will go away if I close the lid for a while. But I do hear a humming and smell a slight burning smell behind this spot on the screen. Just an update, I have a CQ60-420US that had a bad CCFL bulb. I decided I did not want to go down the CCFL path again because a replacement screen was so expensive and I did not like it that the CCFL burned out so quickly so I purchased an LED back-lit LCD screen on ebay for the CQ60-421NR and a converter cable that eliminates the inverter altogether.

I was able to replace the screen by removing only the bezel and screws attaching the screen, It works great but the only drawback is the inability to adjust screen brightness. My daughter has a G50 laptop. The hinges were loose so I followed the instructions through step 15 without touching the inverter. I put everything back together. When I plug the power cord into the laptop, the small light by the power cord port lights up. I press the “On Button, but the screen remains black.

When I hold down the “On” button, the light comes on in the front left of the computer by the “On” sign. When I stop depressing the “On” buttopn, this light goes off. I had the laptop disassembled for about 4 hours. Do I simple have to wait for the battery to recharge? What happened?

Is there a simple fix? Did I ruin the laptop?

On the cq70 there is a caps lock led that the manual says to remove from its mounting clips on the top cover before removing the display it is right above the ethernet port could someone who has taken apart a stock one tell me if it has a wire going to it, and if it does, where does the other end of the wire connect to? The laptop I just fixed someone had lost the plug on the microphone wire and just glued it disconnected to the motherboard problem is, there’s another wire under the glue going to the led and I can’t tell if it’s supposed to be there (even though there isn’t a connector there other than the microphone) or if it’s part of the microphone wire and the person was nuts. Hard to take the display off and apart when you can’t remove the microphone cable lol! They also obviously broke the power button cable connector as it had glue on it (luckily it was still possible to slide the cable in and out of the connection) Oh, and for some weird reason they had glued the dang inverter board laying flat into the screen casing too, luckily I didn’t end up having to inspect it.

Anyways does the caps lock led have a wire? Where does it go? By the way, LOVE your site it’s been useful to me many times and I always check here first when I have a new laptop to take apart! I am working on my Compaq CQ60-615DX. Where your pictures say to disconnect a connector for a webcam, I don’t have a webcam. I do have a red wire and a black wire leading from that connector to what looks like a fusible link that is installed under the cover. I broke the wires there trying to remove that connector.

I am wondering if you know if a broken red wire and black wire leading to that link will disable my computer and if so, where do I get a replacement and what do the other two black wires hook up to in the display. @ Patrick, I don’t have a webcam. I do have a red wire and a black wire leading from that connector to what looks like a fusible link that is installed under the cover.

I broke the wires there trying to remove that connector. I am wondering if you know if a broken red wire and black wire leading to that link will disable my computer Not sure 100% what wires you are talking about. Are they coming from the webcam connector.

If so, it should affect the functionality of the laptop. Just make sure wires not touching each other. Hi I came across this guide after replacing my invertor on a g60, i have the same problem as another poster a few pages back my backlight flicks on for a second when the lid is opened then goes back off again I can still see the text with a torch so the screen cables and inverter are fine afaik, this makes me think its just the backlight thats the problem would you recommend buying a screen or just the backlight? And does a new screen come with its own backlight( I ask this because im worried that the ccfl is a seperate component and that after replacing the screen i would then have to replace the ccfl anyway)? HI LT-Tech. I am having a flickering issue with my daughters HP G50, I ordered a new cable from amazon and started taking apart at step 17, I am now wondering if just readjusting cables could fix???(read all the to bottom of your posting, after getting to this point) I am pretty far in process, actually ready to remove cable from screen.

Question is, would it be worth putting back together and testing, or just wait on cable and complete process??? Is there a quick and dirty way to test cables, without putting all back together??? Also, it does not have webcam do I need to put that cable back in? Final question, I noticed that the antennae wires were shorted in several locations as it went under alignment tabs, could that be causing flickering, bare wires in several locations??? @ Roger, I am having a flickering issue with my daughters HP G50, I ordered a new cable from amazon and started taking apart at step 17, I am now wondering if just readjusting cables could fix? It depends on what was causing the original failure (clicking). If it was just loose connection than readjusting the cable will fix it.

But it’s not very common. If the screen was flickering it’s either failing inverter board, failing LCD cable or failing CCFL (backlight lamp) inside the screen. It’s hard to tell which one is causing the problem without spare parts. Question is, would it be worth putting back together and testing, or just wait on cable and complete process??? Is there a quick and dirty way to test cables, without putting all back together??? No, you cannot test cables. You should be able to test it without putting back together.

Just attach the screen back to the motherboard and turn it on. You’ll need plenty of space to do that.

Also, it does not have webcam do I need to put that cable back in? No, it’s not necessary to connect the webcam. Just make sure the LCD screen is connected to the cable and the cable itself plugged into the motherboard. Final question, I noticed that the antennae wires were shorted in several locations as it went under alignment tabs, could that be causing flickering, bare wires in several locations? Technically, the wireless card antenna cables would not affect image on the screen. I don’t think that’s related to your problem. By the way, how your screen flickering?

If it’s losing the backlight but the image remain on the screen, probably it’s either bad inverter or CCFL. If it’s losing both the backlight and image, probably it’s bad cable. LT It seems like the whole screen was flickering black and white diagonal lines. The computer was not used often, it sat on her desk 98+% of the time and only used occasionally.

I did look for a short in video cable where wraps around hinge, did not see any real wear on cable. I may try tomorrow to test I wont need to put keyboard cable back on??? Should I try to tape the bare spots on antennae wire or is it just making a larger antennea by shorting against lower frame??? I must say this computer is a disappointment, I used my dell lap top daily, open and closing for 3 years and never had screen issues. If I had to guess this unit was not opened and closed 100 times.

This is some real good work you have done here and is very much appreciated. @ Roger, It seems like the whole screen was flickering black and white diagonal lines. The computer was not used often, it sat on her desk 98+% of the time and only used occasionally. I did look for a short in video cable where wraps around hinge, did not see any real wear on cable. That’s definitely not the inverter related problem. Could be bad cable or failing screen. Cannot tell without testing with another cable or screen.

I wont need to put keyboard cable back on??? If it’s flickering even in the BIOS you don’t have to connect the keyboard. You should be able to turn it on without keyboard connected. If you have to login to Windows, you can use an external USB (desktop) keyboard for test. Should I try to tape the bare spots on antennae wire or is it just making a larger antennea by shorting against lower frame??? If the cable is damaged badly, I would probably tape it. Now sure about larger antenna.

I must say this computer is a disappointment Since I moved to Mac all PC laptops look very disappointing to me. Yeah, that’s a cheap model.

Made from cheap parts with cheap labor. LT Thanks, I think it was a black friday special, cheap, I got what I paid for!

I have switched to a MAC desktop also! I have an unopened copy of windows 7 that I bought over a year ago to install on it, but my 03 Sony Viao with XP keeps running so I let girls use office on it for homework and projects. I think the graphics card is started to go though, once in a while I get a blue screen error, and something about the graphics accelerater???

Anyhow, I have not bothered to put windows/office on the mac, my older daughter will use text edit, then send it to her account open in office correct any issues print and turn in. My understanding is that google has some good free productivity software that is completely compatable with office, at least newer versions, mine is 07. And the battle rages on! Again, thanks for the help, as soon as I wake up, I will try screen with cable, the flickering was only occurring when the screen was being moved so I am hoping something with cable! May just be time to upgrade! I’m thinking tablet with productivity software???

Can’t afford to outfit with MACs. LT, Again thanks for your website, I was able to fix by repositioning the video cable on the motherboard.

Like I said in previous post I did get to step 19, then backtracked and tried repositioning cable, and moved it in all directions and it was flicker free. I put back together. The only real iisue I had was screw sizes, I did not keep tract of where the 21 screws came from, 3mm, 5mm, 7mm, 8mm, 10mm.

I used the HP site to sort of figure out, although the screw sizes did not match what I had, i.e. I had no 10mm screws. I think that these were black friday specials, they used whatever parts were available to build.

Anyhow, great site and a I sent a donation to you through your paypal. Much appreciated. This the best, procedure I’ve seen, very helpful. My problem is the BLACK SCREEN that has occurred with mind. When ever I boot up it comes up for few minutes then goes black. I’ve seen where a lot of owners of this model has experienced the same problem. I had it checked and was told its not my inverter, not the screen.

Could it be the backlight that’s bad. I downloaded you screen removal to help me get to it. I’m retired and have a set income, that’s why I’m doing it myself. Would appreciate all help. Thanks Toney •.

I have a HP G70-463CL. It is dated and I use it for A-V entertainment these days. My screen has stopped working completely. It is just white. It used to work when I put some alligator clamps on the sides of the base near the left hinge (on top of where the video cable is located).

I’m sure it is a faulty video cable. Your procedure reveals the video cable. Is the video cable plugged into the screen inverter and is it easy to find a replacement cable? Great tutorial BTW! Are you still taking donations for your site? Karl Wester and Adam were skittish about bezel removal, as was I.

When I speak below of prying the bezel away, my best results seemed to come when I’d lift the inner edge of the bezel and push in a little on the outer edge I was able to easily pry the bezel away from the screen frame at the corner where I removed the left screw. After that, I lifted the inner edge of the bezel close to that corner, away from the screen and the first clip closest to the corner popped out pretty easily. The fourth or fifth clip up the edge, getting close to the upper corner, I required some firm upward pressure to pop that clip. I switched to the bottom, pulling the inner edge of the bezel away from the screen and had some luck with the bezel coming away from the lower edge (the bezel includes the bottom of the screen assembly that comes out and curls down around the wire channel at the bottom). I then rocked the bottom of the bezel as I lifted up on the inner edge of the bezel and clips came away reasonably cooperatively, but got stuck at the right lower corner. SO left and bottom edges were clear, but three corners and two sides remained.

There was a small amount of adhesive holding the center of the bottom edge of the bezel to the screen. I heard it peel apart as I worked my fingers along the inner edge of the bottom of the bezel. Close to the right corner, lifting the inner edge and bottom of the bezel at the same time and rocking back and forth, the right lower corner came loose.

Lifting the right bottom corner and the inner edge o the right side at the same time, rocking back and forth, the first clip from the bottom came free. 2nd and third came pretty quick.

Gentle upward pressure popper the fourth (fifth?) The bezel was flexible enough that with the left and right edges free, I could bend the bezel enough to life the bottom of the bezel off of the wire channels and hinges of the bottom of the assembly. Patient rocking back and forth at the top of the left edge, working both the inner and outer edges, I felt the outer edge give way and the left top corner was free. Working the fingers under both outer and inner edges, I rocked back and forth to free up the top edge from the newly freed corner to the last stubborn corner.
