In the following guide I explain how to remove and replace damaged LCD screen in HP G50/G60/G70 notebooks. I’m installing a new LCD screen into a HP G50 notebook 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 notebooks also known as Compaq Presario CQ50, Presario CQ60 and Presario CQ70.
In most notebooks you can replace the LCD screen without separating the display panel from the base but not in HP G50/G60/G70. In order to replace LCD screen in these models we’ll have to remove the keyboard, keyboard cover and display panel. Let’s start replacing the screen.
Need spare parts for your HP laptop? Search by the part name or number here. You can find the HP spare part number in the service manual. I linked to service manuals at the end of this guide.
In the next post I explain how to remove laptop motherboard.
STEP 1.
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.
STEP 2.
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).
STEP 3.
Carefully lift up the keyboard from the base.
STEP 4.
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.
WARNING! 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 keyboard connector is shown in the unlocked state.
STEP 5.
Disconnect the switch board cable from the motherboard.
STEP 6.
Remove the keyboard cover.
STEP 7.
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.
STEP 8.
Disconnect the video cable connector from the motherboard.
Disconnect the webcam cable from the motherboard.
Pull two Wi-Fi antenna cables through the opening.
STEP 9.
Remove four screws securing the display panel hinges.
STEP 10.
Lift up and separate the display panel from the laptop base.
In the following steps we will disassemble the display panel and remove the LCD screen.
STEP 11.
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.
STEP 12.
Start separating the screen bezel from the display cover.
Continue separating the bezel.
The screen bezel has been removed.
STEP 13.
The screen inverter board is mounted below the screen. The inverter is locked between plastic brackets.
You can remove and replace the inverter board without removing the LCD screen. Simply pull the inverter board from the cover and disconnect connectors on both ends.
STEP 14.
Remove two screws securing the right display hinge.
Remove the right hinge.
STEP 15.
Remove two screws securing the left display hinge.
Remove the left hinge.
STEP 16.
Remove the inverter board from the cover and disconnect one connector from the right side. By the way, this is the backlight lamp connector.
STEP 17.
Remove two screws securing the LCD screen on the top.
STEP 18.
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.
STEP 19.
Remove sticky tape securing the video cable connector and unplug cable from the LCD screen.
STEP 20.
Now you can remove the LCD screen from the cover.
If you are replacing the screen, 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 a screen with the following model number: B154EW08 v.1
The best way to find a new LCD screen for your laptop is either searching by the LCD model number (shown in the picture above) or using the HP part number.
The HP part numbers for LCD screen and other parts can be found in service manuals and here they are.
Service manual for HP G50 or Compaq Presario CQ50 (page 57).
Service manual for HP G60 or Compaq Presario CQ60 (page 4-23).
Service manual for HP G70 or Compaq Presario CQ70 (page 4-20).
After you find the spare part number for LCD screen or any other part, you can search for a new replacement part here. You’ll find many cheap LCD screen replacements.

Rishabh Lakhotia,
At the end of my guide I linked to service manuals for HP G50, HP G60 and HP G70 notebooks.
You’ll find step-by-step disassembly instructions in those manuals. Download one you need and read through.
September 20th, 2009 at 9:14 am

Man, you are one bad Son-of-a-B**ch! I reinstalled a screen on an HP G60 in less than an hour and a half. Thanks for the great instructions
October 4th, 2009 at 9:35 pm
My computer is a Compaq Presario CQ50 -102LA and it is showing me vertical lines on the screen, if i play with the screen and push it was backwards it stops,
So i was wander do you know where i can buy a video cable connector
cause the screen is fine it the video cable connector i need.
Please respond if u can help me
October 7th, 2009 at 9:27 pm
Sham,
First of all, test your laptop with an external monitor. If you get same lines on the external video, most likely you have a failing video card.
If lines appear only on the laptop scree, it could be:
1. Loose connection between the video cable and LCD screen. Try reconnecting the cable.
2. Bad video cable.
3. LCD screen failure.
October 17th, 2009 at 8:29 am
awesome! Thanks a lot this really helped!
October 22nd, 2009 at 6:32 am
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
Thanks
Francisco

I had a HP Presario CQ50 need to replace a screen. The screws are so hard to reach. Thank you for this tutorial. I quickly found the three keyboard screws and 4 keyboard cover screws. After I removed them, I then took out the screen mount and had access to the LCD screen screws. This is a great illustration. Specially thank you for posting the photos. They are huge help. Thank you! Thank you! Thank you!
October 22nd, 2009 at 6:50 pm
Francisco,
1. It’s possible that the video cable got disconnected from the inverter board. Try reconnecting the cable.
2. 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.
October 23rd, 2009 at 6:24 am
Thank you for your prompt reply. I will check the cable and the next steps. Your tutorial is great, the best.
Thanks again
October 23rd, 2009 at 8:36 am
Thank you for this tutorial.
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 couldn’t find how to release the Zero-Insertion Force connector in the manual you linked.
October 23rd, 2009 at 8:45 am
reneviht,
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.
November 3rd, 2009 at 12:34 am
This help me a lot. I was lucky not quickly go to the computer shop and burn my money. My monitor keep buzzing.
Then i tear down my laptop by referring to your post. Disconnect and reconnect the video cable, the problems vanished. My screen became normal like before. Thanks bro!
November 9th, 2009 at 3:10 pm
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. Is this likely to be just a loose connection on the mainboard or do you think the video cable could be broken?
Thanks very much for your kind reply.
November 9th, 2009 at 3:21 pm
Jim Darrowugh,
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.
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.
2. Defective video cable.
3. LCD screen failure.
November 13th, 2009 at 8:59 am
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?
November 13th, 2009 at 9:04 am
Lisa,
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 replacing the LCD screen in a HP Pavilion dv9000 series notebook.
November 14th, 2009 at 3:26 am
i’m having a HP mini, and wanted to replace the cracked lcd, do you have the steps?
November 14th, 2009 at 12:26 pm
annielee,
Not yet. I haven’t had a chance to replace the LCD screen in this model.
Most likely you’ll have to remove the display panel from the laptop before you can remove the screen bezel and access the LCD screen.
November 20th, 2009 at 9:35 am
Hey! POST THE PART ABOUT REPLACING THE KEYBOARD ONLY…I STUMBLED UPON IT WHEN I CLICKED HERE! THERE AREN”T ANY INSTRUCTIONS OUT THERE FOR REPLACING THE KEYBOARD
November 20th, 2009 at 1:14 pm
I just relpaced a laptop LCD compaq perasiro CQ60 an now the screen is all white and ideas? dont tell me I have to take it all apart again..
Thanks
November 20th, 2009 at 1:18 pm
Beverly,
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.
Try reconnecting the cable without taking it apart… and… if it doesn’t work… take it apart and try reconnecting again.
November 20th, 2009 at 1:23 pm
Tori,
Really? Try reading the post again. And read very slowly through steps 1-5.
Let me know if you still cannot find instructions for replacing the keyboard. We’ll figure something out.
November 23rd, 2009 at 2:48 pm
this is a fantastic source. to replace the screen in my laptop a company qouted me $410. I ordered the part online and got it delivered for 145 and installed it myself, could not have done it without the website. Thankyou
November 27th, 2009 at 3:55 pm
This is great. I just finished replacing G60 LCD successfully. I am very much impressed by your step-by-step instruction. This is fanstastic source. thank you very much.
December 9th, 2009 at 9:41 pm
I just replaced cracked LCD with new one. screen boots up solid white. Where did I mess up? would it have anything to do with inverter, could it be wired wrong? need help, any suggestions.
December 9th, 2009 at 9:43 pm
The screen I replaced was in a HP G60
December 10th, 2009 at 10:27 am
I have a hp G60-123CL laptop and one of my kids stepped on it and the screen cracked. I’m not sure if its the 16″ or the 15.6″, how do i measure this? Where would be a good site to buy the lcd screen from thats not too expencessive?? Does these instructions work for this model?
December 10th, 2009 at 2:25 pm
Thank you SO MUCH for this posting. My husband broke the LCD on his CQ-50 laptop last week. We ordered the replacement on eBay and was this close to having some big name do the replacement installation for us. I work with computers, but never had to do this type of work. So I figured I’d look up anything I could about it and I am forever grateful for your info. The steps were very clear and to the point. No mess, no fuss. Thanks again!
December 11th, 2009 at 10:52 am
I started over and pressed tie video ribbon in tighter, works great.
thanks
December 12th, 2009 at 9:50 pm
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?
December 20th, 2009 at 6:25 pm
article was a great help,only problem I had was the lcd connector wasn’t all the way in.
December 21st, 2009 at 10:57 pm
[...] the next post I explain how to remove the LCD screen, inverter board and hinges from the display assembly in HP G50/G60/G70 laptops. It’s similar for Compaq Presario [...]
December 24th, 2009 at 3:59 am
I used these instructions to replace a broken screen.
My first attempt at any PC repair.
Instructions first class.
Thank You.
December 27th, 2009 at 6:12 pm
My son has a Compaq CQ-70 116. Both the hinges have sized up completely making the laptop unusable… the right one sized up first a few months ago and the left one has just sized this week…
He has been getting by with carefully opening and closing the lid, but he has cracked the plastic and popped some of the screws and casing… any ideas on how to fix this one? I can get new hinges, but the other parts??
Any ideas?
January 5th, 2010 at 6:34 am
I followed the step by step instruction given and was able to replace my laptop screen. t took me about 21/2 hours to do it, but it works great now.
The one thing I made sure to do was to create an envelpoe for each step. I placed the screws that I removed during each step into the appriate labeled envelope.
If you do replace your screen make sure to buy a good screen. I went with a less expensive screen because I wasn’r sure if replacing the screen would really work or not.
January 15th, 2010 at 5:36 am
Used these instructions to change out the LCD inverter for my HP G60 laptop. Step-by-step instructions were easy to follow and got the job done.
Thanks a bunch!
January 22nd, 2010 at 7:50 am
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 all…In 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!
January 22nd, 2010 at 9:46 am
Steve,
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.
January 22nd, 2010 at 4:05 pm
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!
January 23rd, 2010 at 8:38 am
Just finished. everything seeminlg went smooth. Plugged it in pressed power….nothing. no power light no fan or hard drive. Have light by power cord and on front panel.
January 23rd, 2010 at 9:56 am
I disassembled and focused on the switch board connector. Not sure how it is supposed to go back together but ended up using the black piece to leverage the cable against the pins. so far so good. If you read this first pay attention to this before taking it apart. The only connector that is not plug and play.
January 24th, 2010 at 5:44 pm
Thanks a bunch. I would have liked a better close up for the power button connector, but couldn’t have done it without this site. Thanks, Thanks, Thanks again.
January 25th, 2010 at 9:47 am
Having the same difficulty as Tom… Everything went back together fine… Press Power and nothing happened. Anyone have any close ups of the switch board cable connector in its proper position?
January 26th, 2010 at 5:47 pm
I’m experiencing a difficulty. After replacing the screen and putting the laptop back together, when I switch it on, I get no display and it doesn’t sound like the computer actually boots up – the power light and wireless light come on (Amber) but nothing seems to move past there.
Any ideas?
January 30th, 2010 at 4:09 pm
I lost the clip that hold the swtichboard cable in place…I’m running into a brick wall trying to find one…can anyone assist?
February 1st, 2010 at 1:33 pm
You are are lifesaver (computer-wise) INSIDE MY LAPTOP! and a special thanks to TOM and Jazzy (daughter) –
I had exactly the same problem Tom did, but was trying to test it without putting all the screws back in (duh!) Jazzy told me to put it together first before I remove the new screen. It works perfectly!
While I’m unemployed I will be sending a donation after I pay my current bills. This makes me want to try and fix my very slow desktop (much later on). Thanks again.
February 3rd, 2010 at 8:31 pm
Your instructions and photos were great! Performed the screen change in about 2 hours with no issues (other than dropping my new screen on the floor – it still worked). Total cost – $109.00
Thank you!
February 4th, 2010 at 6:13 pm

Thank You.
February 4th, 2010 at 7:01 pm
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!!!
February 5th, 2010 at 6:17 pm
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.
February 9th, 2010 at 12:07 pm
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! Thanks.
February 10th, 2010 at 6:55 am
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. dan
February 13th, 2010 at 12:19 pm
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 page…my 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. so…thank you.
February 17th, 2010 at 2:42 pm
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

Stiofain,
Maybe you can fix it using this technique: http://www.laptoprepair101.com/laptop/2009/11/17/fix-broken-keyboard-connector-on-laptop-motherboard/
February 17th, 2010 at 5:01 pm
My problem was yesterday…i was surfing and my screen turn black. Ilaptop run fine with a pc screen. Its the lamp ccfl.
Any technique which could fix the problem, or i have replace the lamp?
You help would be welcome and helpful.
Thank you
February 18th, 2010 at 3:12 pm
Milton,
Is the laptop screen completely black or you still can see a very faint image.
If there is no backlight but the image is still there, could be bad inverter or backlight.
Try replacing the inverter board first.
February 19th, 2010 at 8:01 am
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.)
February 24th, 2010 at 8:15 am
how do you put the screen bezel back together? do you have to glue it?
thanks
February 24th, 2010 at 10:19 am
ryan,
You don’t have to glue it. There should be small plastic latches on the internal part of the bezel. When you install the bezel back in place, you apply some pressure on it and the latches should lock.

Thanks alot for your advice on replacing screen (PresaRIO CQ60).I was doing alright until i found my keyboard wouldnt easily come out and i didnt want to force it but after reading your instructions i knew i had done everything it just needed a bit more force.People like you save people like me so much time and money i think your doing a great service sharing you knowledge.
Many many thanks

Hi Laptop Tech, Will it be the same steps to change LCD panel for CQ40-115AU?
February 28th, 2010 at 11:21 am
Cooper,
Compaq Presario CQ40?
Yes, the LCD screen replacement procedure will be very similar.
Just in case, take a look at this official service manual for Compaq Presario CQ40 notebooks.
The LCD panel disassembly steps are shown on the page 60. Also, in the same manual you’ll find replacement part numbers.
February 28th, 2010 at 9:38 pm
Thank you so much. It works!

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.
March 10th, 2010 at 9:25 pm
This was sooooooo helpful. Not only for the LCD screen fix… but also for the fact that after hours of searching, this seems to be the only inside-view of a G60 on the web. Many thanks!
March 13th, 2010 at 9:26 am
I’m having a lot of trouble disconnecting the webcam cable from the mb in step 8. It looks like the white connector the wires go into should unplug from the white connector on the mb but it is not budging. I’m scared to force it, I’m pulling it to the left & parallel to the mb. Any more info?
March 22nd, 2010 at 3:37 pm
Hi guys. Just replaced screen for my laptop HP G70-120EM using this tutorial. But the problem is when turn on laptop screen goes pink and blue (with very bad brightness, like foggy) without white and black colours…Any suggestions what i did wrong? Many thanks in advance
March 23rd, 2010 at 11:00 am
please could you let me know the order the webcam cables go as i had trouble getting the clip off and the cables came of in my hand
March 27th, 2010 at 4:14 pm
replaced screen now screen has all vertical lines. Did I do something wrong?
Thanks Tom
March 31st, 2010 at 7:08 am
This was awsome instructions…. Thanks
March 31st, 2010 at 2:45 pm
Tom,
Why did you replace the screen in the first place?
Can you test your laptop with an external monitor and find out if external video has vertical lines or not?
If vertical lines appear only on the laptop screen but not on the external monitor, it’s possible that the LCD cable is not plugged correctly. Try reconnecting the cable. Also, there is a chance that your new LCD screen is defective.
April 1st, 2010 at 1:20 pm
Vadim,
Why didn’t you replace the screen in the first place?
It’s possible the video cable is not seated correctly. Try reconnecting the cable on the back of the screen.
April 1st, 2010 at 1:27 pm
After replacing LCD, I get no image, not even with an external monitor, what could be wrong?
April 1st, 2010 at 1:36 pm
Gabriel,
Why did you replace the LCD screen? Was it working before?
April 5th, 2010 at 8:28 pm
Hi,
I have Compaq Presario CQ50 and LCD is cracked. I want to use an external monitor until I get replacement LCD screen installed… how do I connect to an external monitor?
Thanks
April 8th, 2010 at 6:31 pm
I replaced my LCD screen with these instructions. Thank you for your information. I was nervous but it turned out good. Never have done anything like this and it was a success. Thanks!
April 11th, 2010 at 9:01 am
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.
April 16th, 2010 at 7:28 am
Thank you so much for this advice, my daughter dropped her laptop and when we took it to PC World they wanted £250+ to fix it. I have just done it following your instructions and the screen cost me £70 and it is mended and working! If I can do it, anyone can!! Excellent instructions and great pictures. thank you again.
April 19th, 2010 at 12:09 am
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.
April 20th, 2010 at 7:46 pm
Hi, I replaced LCD screen because it was smashed. When I got it all back together it has white screen with multicolor vertical lines Tried remote monitor still no picture. Hve taken sceen out multiple times to check connections
Thanks for your help
April 21st, 2010 at 9:23 am
tom,
Did you see any image on the cracked screen? Can you try connecting the cracked screen back to find out if the image is still there?
April 21st, 2010 at 2:23 pm
Hi, Iam told there was an image on the cracked screen. I threw the cracked one away. When connecting remote screen do you have to configure comp to remote screen?
April 21st, 2010 at 2:38 pm
Tom,
On some laptops you have to configure the laptop to output to the external monitor. Usually you can do it with the Fn key + F* key. You hold down the Fn key and pres one or more times on the F* key which is different for different models.
April 28th, 2010 at 2:27 am
Would these same steps work for my hp dv4? I started out with the green/red line at the bottom of my screen, then a couple of days ago, the screen started flickering during the startup for about the first 5 minutes. HELP!
May 3rd, 2010 at 3:22 pm
For all those worrying about the power switch board cable – see the next article on this web site: “How to get access to the motherboard and substitute it.” which has a very clear photograph showing how it is unlocked. Perhaps Laptop Tech will edit this to include these photographs? Superb instructions very useful.
May 3rd, 2010 at 4:53 pm
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. please how do i get it to show picture, its really geetting me fustrated
May 3rd, 2010 at 8:48 pm
kezy,
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.
May 3rd, 2010 at 8:51 pm
Tony,
I already linked to the motherboard removal guide at the beginning of this guide. Here it is again:
http://www.insidemylaptop.com/remove-motherboard-from-compaq-presario-cq50-cq60-cq70-laptop/
May 3rd, 2010 at 8:55 pm
this is a great post, i was struggling fixing my cq50 series laptop, now i can do it on my own. thnx dude
May 3rd, 2010 at 8:57 pm
i replaced just the lcd screen, i also belive thats the problem but i checked it a couple of times and it still does not change, i was starting to think it was the inverter but am not sure, its there a specific way to place the video cable behind the lcd screen so that it can work,cos i think ive tried all i can.
May 3rd, 2010 at 9:01 pm
kezy,
If the screen is white, it’s not the inverter failure. That’s for sure.
Again, why did you replace the screen? What was wrong to start with?
Can you get video on the external monitor?
May 3rd, 2010 at 9:08 pm
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.
May 3rd, 2010 at 9:14 pm
kezy,
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.
May 3rd, 2010 at 9:22 pm
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
May 3rd, 2010 at 9:28 pm
kezy,
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.
May 3rd, 2010 at 9:58 pm
thanks you were rite its working now, thank you very much

Just wanted to know the list of materials I will need to fix my laptop screen.
May 10th, 2010 at 11:18 am
OK, I did it and it works !!!!! I spent about four hours including a half hour break. I had trouble getting the hinges back on until I realized I had the side braces reversed.
Suggestion, use some small cups to hold the screws. They are small. I keep yogurt cups around for things like this (and kids painting). Use sticky notes or even just small pieces of paper to note where they belong.
A magnetic #0 or #1 Phillips screwdriver really helped.
May 15th, 2010 at 6:37 pm
step 6 – Remove the keyboard cover
I pulled up the front and see a few tab’s, how do you move the sides or display side? I’m stuck here.
May 18th, 2010 at 8:33 am
I was glad to find this guide…it 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 rate…any suggestions from anyone?
Thanks in advance for your answers.
May 19th, 2010 at 1:50 pm
I saved myself $145 by following these instructions. The new screen works perfectly. Definitely worth a little donation!

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.
May 22nd, 2010 at 10:34 pm
Maria,
Wait for a few day. Maybe the moisture will evaporate. It not, you’ll have to replace the screen or use it as is.
May 24th, 2010 at 12:58 pm
I’m a real novice an having problems disconnecting the webcam cable from the motherboard ,dont want to be to forceful or does it clip out?
would appreciate any advice

I need to replace a screen on a presario CQ60-404ca laptop. Will any CQ60 screen work or do I have to get specifically a CQ60-404ca screen. Thanks
June 3rd, 2010 at 1:34 pm
I replaced my g60 screen and i got a white screen. I double checked all my connection. Do you know how to fix this. I installed the screen without a grounding strap =/ i dunno if that is why i have this problem
June 4th, 2010 at 5:09 pm
this jazzbone does indeed know his stuff- took me about an hour and a quarter, went through no problems. thank you very much- just donated.
June 5th, 2010 at 12:08 pm
One thing you need to STRESS is, when removing the keyboard ribbon connector, lift up on the black lock before pulling ribbon out. I did not, didn’t know to lift the black locking piece, broke the lock off, now looking for a new motherboard, due to the keyboard ribbon will not stay connected.
June 6th, 2010 at 7:10 am
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 black…now 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 backlight…but there is no part number for the backlight….how do i figure out what i need…and can you show the steps….it be nice if they were on here.
June 6th, 2010 at 6:49 pm
Ivan De La Rocha,
It’s not easy to replace the backlight lamp in a laptop screen. I would suggest replacing the entire screen.
If you still would like to try it, take a look at this guide:
http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/
June 6th, 2010 at 7:11 pm

I believe I mentioned that in my post.
Can you try this method to fix the keyboard connector:

Why did you replace the screen? What was wrong with the original screen?
June 8th, 2010 at 5:37 pm
where can i buy a screen for my hp g60 at? please respond to email or ill bookmark this page thanks
June 11th, 2010 at 4:32 pm
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?
How similar is replacing the LCD screen in this model to replacing an LCD screen in a Toshiba Satellite? I have a Satellite A205-S5000 and I was hoping I could either use this guide to replace mine, or you could publish a guide for the Satellites. Thanks!
June 12th, 2010 at 9:34 am
Ticklinivorys,
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.
2. Bad LCD screen.
3. 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.
I publish Toshiba guides here: http://www.irisvista.com/tech/
Take a look at Satellite A210 display disassembly guide, I think it’s very similar to Satellite A205.
June 12th, 2010 at 3:48 pm
andrew,
Have you tried searching on Google or ebay? When I search for “Pavilion G60 screen” I get many results.
June 13th, 2010 at 9:44 am
I’ve followed your direction and am back to step 6 but I can’t get the locking clip in in front of the blue cable. Could you give me a few directions on which way it goes in and perhaps a picture? Thank you.
June 13th, 2010 at 9:51 am
Shelly,
Carefully lift up the further side of the locking clip (which is closer to the LCD) with your fingernail. The locking clip will open up at a 90 degree angle. After that you can release the cable and remove it from the connector.
June 13th, 2010 at 10:13 am
Thank you but I’m going the other way. How do I get the clip back in? I’ve been working on it for an hour.
June 16th, 2010 at 7:24 am
hello, can you please repair my LCD screen?? because it got worse.. many line appearing and always flickering… please can you repair my laptop compaq presario cq40.. i will pay you
June 18th, 2010 at 7:25 pm
Thank you very much for your instructions. They are awesome!!!!!!!!!!!!!! Did it my first try and it took fore ever. lol. I did end up braking that piece in step 4 though lol. It’s ok I only broke the corner piece so it still holds the keyboard thingy in place. could you send me a po box number so I could send a donation via male. Thank you thank you.
Sincerely
Eric
June 24th, 2010 at 11:01 pm
hi i got a compaq cq61…i got a question …where do i get the screen inverter…how do i know which one to buy and there is no wriyngs on it but there are numbers on a white sticker ………i’ve searched for inverters but don’t know which one, would it matter if i bought any kind? i need help finding one.
June 24th, 2010 at 11:28 pm
gold,
Take a look at the sticker on the inverter board. Try googling any number strings you find on the sticker.
Search HP website for the maintenance and service guide for your laptop. Usually you can find part numbers in the manual.
You have to search for a compatible inverter.
June 29th, 2010 at 9:29 pm
Thanks for the tutorial saved me alot of time!
June 30th, 2010 at 10:11 am
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.
June 30th, 2010 at 11:01 am
to follow up….the LCD was replaced because the screen was cracked. Prior to being replaced, the old, cracked screen would light up and would display the start up screen appropriately (if now all cracked and broken looking).
June 30th, 2010 at 1:48 pm
I was wondering how and where i could order some mounting brackets for a CQ 50-215NR?
June 30th, 2010 at 2:52 pm
Nathan,
Are you talking about LCD screen mounting brackets? Here’s the part number I found in the service manual:
486559-001 Display panel brackets (includes left and right brackets)
I guess if you google the part number, you’ll find it.
Here’s laptop service manual.
July 2nd, 2010 at 12:06 am
HI¡
Thank u so much for the explanation, but i have a question.
I have a Compaq Presario CQ50-102LA, and it looks exactly the same as the one u have here.
I was replacing the keyboard, and i found that the cable tha is supposed to be “the webcam” u signal here http://www.insidemylaptop.com/images/HP-G50-G60-G70/remove-replace-lcd-screen-10.jpg was unplugged.
The question is.. If that is the webcam cable, why my webcam is working perfectly if this cable is unlplugged?
Could it be the microphone cable instead?
July 2nd, 2010 at 12:06 pm
i have vertical green stripes on the display of my cq60. how do i know if the problem is the inverter or the display?
July 8th, 2010 at 1:53 am
Dude, thank you sooooooo much for this post! I was really close to having it fixed somewhere else for waaaay too much money, but this post saved me time and money. Thank you. This is GOLD right here lol. Keep up the good work!
July 11th, 2010 at 9:17 am
Hi 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 will do the repaire myself using you exerlant tutorial. Thanks
July 12th, 2010 at 10:17 am
lincszx,
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.
July 14th, 2010 at 5:27 pm
hey 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
July 15th, 2010 at 8:32 pm
chas,
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.
July 15th, 2010 at 9:32 pm
hey 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 also think the the power lock mite be on bc i did put a screwdriver in it wen i was taking it apart idk y though lol
July 17th, 2010 at 12:30 pm
chas,
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?
July 18th, 2010 at 10:36 am
I have the Presario CQ60 when i try to boot the laptop it bootup all the way, but when its time to load to the desktop i didnt see anything. The back lit is working cause i can see my mouse is moving. Is it my vedio card?
July 18th, 2010 at 11:18 pm
John,
I don’t think so. Most likely corrupted Windows.
Can you boot in Safe Mode? Press F8 on startup and select Safe Mode.
Also, you can try Last Known Good Configuration to revert Windows back to the last successful login.
July 21st, 2010 at 1:34 am
Hi, great tutorial, I have a G-60 and when it turns on the screen is black, I’ve tried connecting to an external monitor but it will not display either, I’ve disassembled as far as the keyboard to make sure the video cable is securely connected which it is, what do you think I should try next?
July 21st, 2010 at 5:33 am
Awesome disassembly. I have referred to this guide twice in the repair of this model, and it is accurate.
July 22nd, 2010 at 6:01 am
I did the run-in test and it locked/froze up and now when I start up its just a black screen, no prompts and cant seem to find a way to the bios.
The command line.prompt appears up in the top left corner for a second then nothing happens.
The fan is going and it seem that its doing something, I tried a hard reset and still nothing.
It was working fine before I did this run-in test?
Please help!
July 22nd, 2010 at 11:03 am
Jeff,
Is the screen completely black and blank?
Could be memory failure. Try reconnecting memory modules. Remove memory modules one by one and test the laptop with each one separately.
July 23rd, 2010 at 12:58 am
Thanks for the reply. 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.
July 23rd, 2010 at 1:06 am
thanks very much. its expensive for laptoop maintenance here. students who have a little idea about the inside and cant really spend much for maintenance cos the cant get to the inside, you gys really help alot. thanks alot guys
July 23rd, 2010 at 10:17 am
Jeff,
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.
July 23rd, 2010 at 10:45 am
Hi I am having some difficulty with my neices compaq cq60. The screen is hard to see at login and when windows starts as long as you have a bit of light you can see it. I have changed the inverter but to no avail. I see in step 16 it mentions a backlight connector but when i pulled it apart i see cables going into the top of the lcd back screen but cant see a bulb. Please help before i pull all my hair out. Thanks in advance

Yeah it looks like it is the motherboard or at least the video component of it. Thanks for all the help, you’re invaluable!

I used these directions to swap out the cracked screen in my husband’s laptop. Your instructions were perfect and very easy to follow. The only problem is…I got it all put back together and now only have a plain gray screen when I turn it on. Can you tell me what I forgot to connect? I’ve taken it back apart 3 different times and followed your steps to try to find which step I forgot to connect something and can’t seem to find it.

A wonderful example of sharing. I have replaced my daughter’s screen successfully saving at least 200$. Thanks. 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

Hi!
Beautiful explanation and instruction for replacing an LCD. But I’ve got a problem. In the process, I have lost the small plastic that holds the keyboard cover’s switch board cable to the motherboard. And now my laptop wont turn on. Any idea where I can buy it and how it’s called?

I have a Compaq Presario CQ60 which has a seriously dodgy screen, whenever I move it back for adjustments, I get all these line on the screen which fades completely blank (white)… what shall I do, the screen has just been replaced and i’m still having this problem.

Thank you Thank you Thank you! Thanks to your precise instructions, I was able to change out my laptop screen after my dog bit it. It works perfectly again. You saved me about 2
$200 bucks.
Thanks!

Hi,
Thanks for posting this very helpful guide. However, my hp g50 lcd starts to flicker with horizontal lines months ago and it’s getting worst, any thoughts for the specific cause of the problem? Please help.
August 2nd, 2010 at 5:46 am
Great site.
I have a cq70-200 with a cracked lcd. I will wordk on an external monitor but it’s being only activated when vista is already started. When i want to see also post messages and/or go into BIOS do i have to loosen the video connector from the motherboard to direct activate the external monitor?

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!

Costa,
I don’t know how far you disassembled the notebook. Did you remove memory modules? If you did, make sure both memory modules seated correctly.
August 15th, 2010 at 2:28 pm
No, I did not remove them. Checked them today and they are seated correctly. Also checked if all the cables are pluged in. They are. I,m afraid I am gotta send it ro hp repair centre!

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?
Thanks.

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

Thanks for this site. It really helped and saved me a ton of money. Cheers.

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.

How do I remove the screen inverter cable? Do I pull on the wire or the white plastic thing? Thanks.

Hello Laptop Tech
I have replaced the LCD screen on my friends HP G61 with a working LCD screen but now the laptop wont turn on. The green power light turns on as if the battery is charging but when i touch the power button nothing happends?
I can only think that I snagged the VGA cable when I look it off so have ordered one of ebay would that stop it from booting though? If I cant fix it im going to have to pay for a new laptop for them :O(
Thanks

Paul,
Turn off the laptop, remove the battery and wait for a few minutes. Now plug the AC adapter into the laptop and try turning it on.
Try this first.

Thank you very much for taking the time to share this guide. It was invaluable in helping me to fix my daughter’s laptop screen.
August 28th, 2010 at 11:32 am
Jonathan,
Do not pull the wires. Pull on the white plastic connector.

Hi,
I have replaced the screen on my G60 which is great, however, when reconnecting the on/off board, the black clip on the connector was knocked and came away. Now, the laptop will only power on when the cable is physically held down as the clip will not hold it down correctly.
Is there a way to fix this that doesn’t involve buying a whole new MOBO?
Thanks

Hello,
I just replaced my screen and everything works but the webcam. Any ideas?
September 2nd, 2010 at 7:12 am
Thanks for the instructions! They worked out perfectly. If you are just replacing the LCD panel you do not have to remove the screen inverter, but remember to disconnect the right side cable running from the LCD panel to inverter.
