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.

Hi, thanks for presenting all these solutions.
I got a HP Pavilion dv9780 and it has a weird problem. The screen stays black when I start the laptop with the screen open to 90° to the keyboard, basically a right angle.
It starts with a normal screen when the angle is bigger, means the screen is pushed more open.
When the screen stays black, the latop is booting and all perfectly and can be used with an external screen. And now the interesting part. I tried to push fn + f4 while being in 90°. Nothing happened. When I open the black screen to a wider angle, nothing happens, when I push in a wider angle the buttons fn + f4 the screen suddenly appears with the booted laptop and I can use it, when i move the screen back to 90°, it stays on.
I opened the laptop and also the screen to see if there is a obvious problem with the cable or connection that gets stretched or whatsoever while being in 90°, I also unplugged and plugged back the inverter. Anyway, I couldnt see any problem there and after closing it all, the problem still remains. Couldn’t find any forum entry or so for this problem. No warranty of course anymore.
Hope to find a solution here

Steve Hannigan,
In my guide I show inverter board for a screen with single backlight.
Here’s an example of dual inverter. Do you see two connectors on the right side?

hello…in your article on removing the HP LCD screen you described the Inverter and its connectors. I am confused!
Let me please quote what u said in your article…(Instead of one connector on the right side (as it shown on the picture above), the dual inverter has two connectors)
The picture you show has 2 connectors??? Does this mean there should not be a connector on the left and right if it is a single backlight??? Or…do you mean the right side has dual connectors???
Thank You
sorry for being stupid

I recently received a dv9000 as a hand-me-down from a relative. It looks like it has seen some abuse, but I think the biggest problem is the screen. The hinges seem a little loose, but the screen is totally black- no backlight. If I angle it just right, I can sort of see what is going on, but it is very faint. My question is: should I simply replace the screen, or do I need to do the inverter part, too? Also, will the loose hinges affect anything?
I am prepared to spend a little bit of money, seeing as how the laptop was free for me
but I have looked at the rates to repair laptops and I don’t think I can afford them!! Plus, if the laptop is already kind of iffy, I’m not sure it woud be worth it. These instructions are great, and I’m really not tech-savvy at all. Thanks for the help!

Yory,
Most likely they are interchangeable.
You should ask this question the seller.
I think if the screen has same size, resolution, and compatible with dv9000, there shouldn’t be any problem.

Thank you.

Thanks for your reply.
So I guess I should be looking at getting new screen. Speaking of which, when I browse ebay offerings I see glossy and matte screens for dv9000. Are they interchangeable? Mine is glossy, but I would prefer matte.
Anything else I need to check or any screen listed as “for dv9000″ would do?

Yury,
I think it’s failing LCD screen.

Hi,
My 2 year old dv9000′s screen is starting to get darker and yellower. I compared it with the 15″ version of the same laptop and the screen there is definitely brighter and has no yellow cast.
What can be the reason? I am prepared to replace parts but have no idea which one is failing.
Thanks,
Yury
