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.

@ Jackie,
Carefully separate the front bezel from the screen and look at the inverter.
If your laptop has dual backlight, the inverter will have two white connectors plugged into the left side and two more connectors plugged into the right side.
If your laptop has single backlight, the inverter will have one connector on the left side and one on the right.

Your instructions are great! Before I change the screen may I ask you some diagnostic questions? There are 2 symptons: 1. either the screen dims intermittantly or 2. completely shuts off. When we hook up a remote monitor everything is good and steady. What could be the problem? Do you sell parts?
Thanks again for your help.

@ Chelsea,
You cannot tell if this is the inverter or backlight failure just by looking at it. Both have the same failure symptom – no backlight.
I would try replacing the inverter board first, it’s not very difficult and the inverter is cheap.
If it doesn’t fix the problem most likely this is backlight lamp related problem. In this case you’ll have to replace the screen.

My laptop was working fine last night and when I opened it this morning, it was very dark but could see a faint image so I grabbed my phone and turn the flashlight on i could see pretty much everything on it. What do you think is wrong? The inverter or the backlight? Need help! Everywhere wants at least $100 to diagnose the problem… then an extra $300 just to send it out to get it fixed…Help please

hey my daughter broke the left hinge years ago (screen stopped working) and after using it connected to the tv for the past yr and a half the other hinge has snapped so i have disconnected the screen and taken the entire panel of, only the screen is salvageable i will have to buy the whole plastic cover and refit them, would the removal or the back screen stop my net from working? i have such poor signal its hard to get connected also would the snapped hinge have stopped the screen from working or will i need to replace all cables too?
