HomeIn this guide I will explain how to disassemble the display panel and remove LCD screen with inverter board from a HP Pavilion dv9000 series laptop. Do not disassemble your laptop if it’s still under warranty.
You’ll find instructions for removing hard drive, memory, wireless card and keyboard in my previous post.

LCD screen and inverter board removal instructions.
First, remove the battery. There are five screw seals located on the LCD screen bezel. Remove all five seals with a sharp object. Remove all five screws found under the seals.
Now we are going to remove the LCD screen bezel. Insert your fingers between the bezel and LCD screen and carefully disengage plastic latches.
Continue removing the bezel.
LCD sceen bezel has been removed.
You’ll find the inverter board under the screen. Carefully unplug cables from both sides of the inverter board. Remove the screen inverter and replace with a new one if needed.
NOTE: some HP Pavilion dv9000 laptops come with dual backlight and require a dual inverter board. Instead of one connector on the right side (as it shown on the picture above), the dual inverter has two connectors.
In the official service manual for HP Pavilion dv9000 I found the following part numbers:
Display inverters:
For use with Dual Lamp display panels 432959-001
For use with Single Lamp display panels 431391-001
Remove three screws from each side of the screen. These screws securing the screen hinges to the cover.
Now you can access the back side of the screen. Carefully remove sticky tape securing the video cable. Unplug the video cable from the screen.
Remove two screws from each side of the LCD screen. These screws securing the screen to the hinges.
Remove the screen and replace it with a new one if needed.
Note: some HP Pavilion dv9000 laptops come with dual backlight LCD screens. On the picture above the single backlight lamp LCD is displayed.
The dual backlight LCD has two backlight cables.
In the official service manual for HP Pavilion dv9000 I found the following part numbers for LCD screens:
Display panels:
17.0-inch, WXGA+, TFT Dual Lamp display panel with BrightView 432954-001
17.0-inch, SXGA+, TFT Single Lamp display panel with BrightView 432953-001
17.0-inch, WXGA+, TFT Single Lamp display panel with BrightView 432952-001
LCD screen, bezel and inverter have been removed.
This model has a known issue – broken left hinge. In the next post I explain how to remove and replace the broken left hinge.
If your HP Pavilion dv9000 notebook has no video at all, it could be related to the video chip failure on the motherboard. Take a look at this video tutorial explaining how to fix failed video chip in HP Pavilion dv9000.

Jesus,
You are correct, it’s not the inverter board problem. If you can see the screen (even with garbled video) it means the backlight and inverter work properly.
You said the laptop works fine with external monitor, so it’s not the video card/motherboard failure.
Most likely it’s either bad video cable or LCD screen failure. I cannot tell which one is causing the problem without testing the laptop.
You can disassemble the display panel and try moving the video cable while the laptop is turned on. If moving the cable affects image on the screen, probably it’s bad video cable. If video not affected and stays bad all the time, most likely you have a bad screen.

can you make a video doing this. I feel that making a video will make it more easier to follow. I have the same laptop on the pic ur using and my lcd is not working. I know its my lcd because well it can’t be my inverter or my video cable because when i hook it up to another external monitor. It looks perfectly fine. My screen just looks very pixelated and i can bearly read the text. It use to flicker white and yellow but lately it hasn’t , but its still pixelated. Ima buy a lcd from ebay, do you think its the lcd?
plzz reply when u can,
-thanks

@ JZ
should be the video cables going up through the hinges. i had the exate same problems. the cable had been tearede from opening and closing the screen trough the time. no problem to change…

Thanks for the reply. I think the 2 bulbs is what they use for there Bright view screen but to be honest I can’t tell the difference with just the one bulb plugged in. It is plenty bright. I think the other bulb is bad because it doesn’t light up as bright on the left side and bottom of the screen of the screen. I am going to leave it with the single inverter and plugged into the one bulb for now. I will get another inverter to try and see if the other was faulty.
Thanks, again
July 17th, 2010 at 9:54 pm
Dominick,
I think it’s possible. Maybe the inverter has to be loaded by two lamps in order to operate properly.
Could be.
I think so. These two backlight lamps should be similar and if both lamps are good they should work with the single inverter.
I think one of the lamp is bad and it’s screwing the dual inverter.
Sorry, I cannot give you better advice. Most dv9000 I fix have LCDs with one backlight lamp. Please let me know if you find the solution.

Hey there,
I have a DV9000 with the dual backlight. I have a screen that would stay on for a few seconds and then go black. I can see the the image faint so at first I thought it was the inverter. I put a new one in and it still has the same problem. If I remove the feed cable from the inverter and put it back in the screen comes on for a few seconds then shuts off. I then started to think maybe the cable but moving the cable around by the hinge or by the inverter board does not do anything. I had a single backlight inverter lying around and tried that. The screen stays on with it. I tried the other backlight feed but it does not come on. It seems that only one bulb is working. Could one bad bulb be causing it not to stay on with the dual inverter installed? I hope I am explaining this right. Right now I have it working with the single backlight inverter connected with the blue wire harness. The red wire harness connected does not light up. Could the new dual inverter be bad? Should I get the light if I connect the Blue and Red backlight wires one at a time with the single inverter? Any other ideas?
Thanks for your help.

I have a dv9700. I’m having issues with my screen but I don’t think it’s the inverter or the backlight. I get a display on the monitor but it’s all artifacty (is that a word) and faded. But there is color and if you manuever the screen back and worth sometimes you can get a clear picture. Connecting to an external display you get a perfect picture.
I removed the screen bezel to check out the inverter. I noticed that it looks like it’s pinching the cables near the left hinge. I had the computer on at the time and notice that if i moved the wires away from the hinge i got a perfect picture.
Any ideas on what to do to resolve this. I’m going to try and investigate further this evening to see if the wires are damaged at all.

I have an HP pavilion Entertainment PC DV2000 and I am having problems with my laptop. When I turn it on it lights up with the HP logo then turns completely black. If I move the angle of the laptop I can barely see the screen. I was told I had to replace the LCD inverter so I did but it still does not light up the screen. Do you have any advice on what I can do? Thanks
June 19th, 2010 at 8:52 am
Thanks for a bit of help. I did follow your website and had similar problems as Matt Bondy. However , it was a bit of blue tint to my screen at certain angles. I used your informative page to open my display. Would like to submit to you photo of the culprit. The problem , after referencing the HP service manual parts manual, would suggest an engineering oversight, rather than, an assembly defect. Once you see photo , I am sure you may agree. A simple bushing for cable could have worked. Thanks for your website, keep up the great work, saved me $$
Best Regards,
Dave
How can I share photo and finding?
Going down this week to HP and having them replace harness for free, I am sure!
June 6th, 2010 at 7:09 pm
Louise,
The image is not clear on the external monitor?
Can you test the laptop with another external monitor? Maybe your monitor is not good.
This description sounds more like LCD screen failure.
June 5th, 2010 at 2:13 pm
I have a HP Pavilion DV2000, when it is switched on the screen lights up white and then slowly fades to black. The machine is booting up but no image. When connected to an old VGA monitor the image is not clear and hard to make out. Do you think this is a screen problem or a motherboard problem?
Any advice would be appreciated.

I have a HP G71-345CL and need to replace the screen. Where are the screws located to remove bezel. I can’t find them.
April 10th, 2010 at 4:16 pm
Hi,
My brother’s HP dv9000, (9022ea to be exact) was dropped and the front bezel and cover were damaged. The screen seems to work fine, in fact the computer seems fine apart from the damage to the screen bezel and the top cover.
1. How can I tell if I require bezel with dual or single lamp.
2. Is it worth while replacing both hinges while I’m at it?
3. My brother ruined a few screws trying to get them out, (wrong screwdriver), can I buy a set of screws for the screen only?
Thanks,
-Ged

My girlfriend’s acer laptop’s hinge broke sometime ago and she has been using my external monitor. Since the laptop screen was not working she cut the wires connecting the screen (near the hinge) to separate it all together. Its a stupid thing to do but now though the computer works fine with the external monitor the wireless capability is lost. I read in your above post that the wireless antenna cables run inside the display panel and that obviously is now severed.
Since the laptop runs fine, I don’t mind it sitting at the desk like a thin desktop as you said, buts it no good without the wireless capability. Is there any chance the wireless could be restored using an external wireless card or something else. I was even considering opening the dismantling the screen step by step and looking for the lost component and trying to rewire it back to where it was cut off from. Its will be interesting if I can make it work again. I am no geek, so it will be gr8 if you could possibly explain in detail… appreciate ur help.

Dale,
Take a look at this guide for HP G50/G60/G70 notebooks:
http://www.insidemylaptop.com/remove-replace-damaged-lcd-screen-hp-g50-g60-g70-notebook/
Should be the same for Compaq Presario CQ50, Presario CQ60 and Presario CQ70.
March 31st, 2010 at 3:46 pm
Marc,
First of all, this could be software related failure. Try reimaging the hard drive back to factory defaults. Run the recovery disc and reinstall everything back to factory defaults.
If the problem still exists, most likely this is the graphics card failure. It’s a known issue with HP Pavilion dv6000 series notebooks.

I have a hp compaq presario cq60-420us and I am looking to replace the lcd screen, however the laptop does not appear to screws on the bezel. How do I remove the bezel to replace the screen?
March 13th, 2010 at 12:31 pm
Hi, I have a similar connector to that in picture five (5) above (the one with the inverter)
Am I to understand that the picture indicates a 1 CCFL screen type?
Thanks!

Hi, I have an HP Pavilion dv9000 about 2.5 year, and for now the story is not what i like.))
1) The mous pad doesn`t work in about 6-8 monthes, it reacts strangely or it move so sharp and stack or no any moves, what I`ll have to do with that ??
2) First it did fall flat to the ground from 0.5 m, the screen is when laptop is boot up Windows XP, looks burgundy in color the whole screen, after it if I`ll use it for to watch pictures, fotos, the parts of the screen looks burgundy and saturated , and it has a greenish tiny vertical strips at the whole screen.
I went to chek it to computer store when they plug it in to regular monitor it shows the screen working well like a brand new, so please tell me do I`ll really have to replace to the new screen ???!!!
Thanks

Hello,
I just changed my LCD Screen on my HP Pavillion DV5-1225ca. When I turn on my laptop now
the screen will light up white and then slowly fade to black. What did I miss???
Thanks

Hi, Thanks for the Great job and a great help you give so many of us. I have a HP ZD81200cl, I have read all the past post on panel problems, mine seam to fit in to many of the discriptions listed. Narrow verticle lines, a line that is vertical and about 2 inches wide that is white on the left side of screen, but after it has been on for a few minutes, slowly disapears and screen is back to normal. I pluged in another monitor (flat panel) I had as you sugest to do, and everything looks great. no lines or white spot.
My question is, My panel is a 17″ LG Philips LCD LP171WX2 (A4) (K1), 1440X900, I am having trouble finding a panel like this but there are many that are LP171WX2 but have a higher resolution. Will the higher resolution work on my computer? My external panel is much phigher resolution than my laptop and it works with no problem, so I take it from that that my video card should have no problem handeling the higher res. Or am I missing something?
Greatly would appreciate your input.
Thanks Serge

Thanks for the great guide! I’ve started having an issue where half the screen was flicking (Dual lamp Inverter model I’m guessing). Now its just not lighting up at all. I pulled it all apart, gave it a few nudges here and there and it worked again! Problem is I have to do this all the time now. I tried nudging all the cables while its running and can’t get it to flicker so I’m thinking its the lid switch going awry, can you tell me where it is so I can have a look at that, I can’t find it!
Thanks heaps again!
March 2nd, 2010 at 10:47 pm
Dustin,
It’s possible that the cable is damaged.
HP Pavilion dv9000 notebooks are known for a problem with the left hinge, that’s where the cable is running.
Take a look at this guide:
http://www.insidemylaptop.com/how-to-replace-broken-left-hinge-in-hp-pavilion-dv9000/
In a case like that, I would remove the screen bezel and keyboard cover. After that turn on the laptop and try moving the cable while the laptop is still running. If moving the cable affects video on the screen, it’s likely the cable is damaged and has to be replaced.
Proceed at your own risk. This is not for beginners.
March 2nd, 2010 at 8:30 pm
I’m having a weird problem that I’m not positive how to fix. I can’t find someone that has dealt with the same problem specifically. I have a DV9000 and when I move the monitor back the screen goes black, move it forward and it comes on again. It seems to only like certain positions, really favoring the “closed” end of things. Best I can figure is that it is a pinched display cable but i’m not positive. If this is the problem i’m really not sure of the part number I need to order. 432962-001 seems like the right one but I don’t really want to pay 80 bucks for the wrong part. Can you help me out?
Thanks!

I have this same laptop (HP dv9000 series) . The gpu just fried cause the laptop kept over heating really bad. I wanna know if i can use the lcd from this laptop and find away to use it as an lcd for my psp. what i wanna do is build the lcd and psp into the headboards for my daughters bed, and hard wire a ps2 (which i know how to do that at least) controller, this way my two girls can watch anymovie they want and play any game they want with out fighting over the tv or game systems. i think its a pretty good idea, and i will prolly have to find away to connect the laptop lcd screen to an external power supply, cause i am sure that the psp wont handle the requirements powerwise of the new lcd but it should be able to handle the bigger screen since it is able to be played through the computer with certain software mods and through the tv with other connections. but the goal for me is to rebuild the whole system bigger and better into the headboards of my childrens beds, well footboards anyway. this is my idea and i hope it doesnt get stolen and my name is Crystal Stophlet and the date is 2-17-10.

Matt Bondy,
You’ll have to test your laptop with video on the external monitor.
Connect the monitor and set the laptop to display video externally. Do you get same distortion on the external monitor when you move the laptop lid/screen?
February 8th, 2010 at 4:27 pm
I have an HP dv9000 series laptop. It is functional but lately I have noticed a slight distortion when I change the angle of the lid/screen. Is this indicative of a specific problem?
Thanks,
– Matthew Bondy
