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.

Hello,
I removed my cracked LCD screen and took out the inverter. There is a set of black and white wires that ran out of the inverter. I broke the white glass tube. Where can I find a replacement and do you have any photos or instructions on where those wires are supposed to go? Thanks!

My HP Pavillion 9000 is 17 months old. The left rear lower corner of the cover (as you face it) has cracked, the hinge has virtually frozen up and now the screen cover has cracked. Is this a common occurance on these? I’m handicapped and never take my laptop out of my room and always close it from the center…Thanks

Peter,
It’s hard to tell. Could be bad backlight lamp or could be bad inverter. The only way to find out is install a known good inverter and test the laptop.
I would try replacing the inverter board first. It’s easy to replace and shouldn’t be very expensive.

Thanks for all the info. I just had my DV9408 motherboard replaced under the extended warranty as it would not start (blue lights would just flash and keep trying to restart). When I got it back, it started up but the screen is dark (like looking through a deep tint). External monitor works fine and when lid is closed, the system goes into standby ok so lid switch is ok (for those looking, the lid switch is located under the speaker cover near the start button and is glued to the heatsink). I am going to try to get HP to cover the screen under the extended warranty but they have said intially that they won’t as there had been a spill (which is true but was minor about 1 year ago and everything had been working fine, including the screen). If they do not cover this, am I safe to presume that it would be the inverter? The HP rep thought it would be the backlight but they really did not seem to know. Again, great site. Thanks for the info.

michelle,
I cannot tell you what is wrong without testing the laptop. Yes, it’s possible that you have a bad motherboard.
Could be connection relate problem, bad memory, bad video cable, bad motherboard, etc…
It depends on the model of your laptop. Could be $100 or could be $500. You didn’t give me enough information.

Thanks so much in your INFO about removing the screen as i only wanted to remove the inverter as mine was dark on one side of the screen. I got the part number and order the new part and having installed the old inverter my screen is tops again. The new part is costing $23 AUD and a shop wanted $300 AUD to do the same job. I cant thank you enough.
