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.

Can I remove the rest of the screen case. The laptop still works with an external minitor but now the screen is just in the way.
Thanks!

I mistenly left this on the wrong blog previously. My bad. I followed your instructions about replacing the inverter on my hp dv9000 but I still get a screen that can only be displayed by using a flashlight. Any other suggestions?

Thanks for the useful post. Unfortunately, when I followed the instructions using my HP Pavilion DV9000, the inverter looks nothing like the one you have pictured above. Mine is twice as wide and has two plugs on the right hand side. The part I ordered from your link obviously is not compatible, so I have a useless part now. Where can I get the correct part?

Hi Laptop Tech,
The new LCD Screen its brand new! but the Laptop shuts off with the old one and the new one.! when i remove the cable from the motherboard the laptop contiuons ON and i can connect and external monitor and it works perfectlly.! what do you think it could be?

MasterM,
What if you install the cracked LCD screen back into the laptop, will it stay on?
If the laptop stays on with the old cracked screen but shuts off when the new screen is installed, apparently the new screen is not compatible with you laptop and maybe requires a different video cable or the new screen is defective.
Before you jump to any conclusion, test the laptop with the old screen.

Neil,
Apparently it’s related to the video card and means the whole motherboard has to be replaced.
I don’t know any I can suggest. Find the motherboard part number (SPS number in the memory stick) and google it. You can find a seller this way.

Thanks for your prompt answer. I have tried with an external monitor but the output is a scrambled screen of small squares. Can you suggest me a web page to order the motherboard? Is replacing this motherboard too difficult to do it myself?

Neil,
For some reason, your description sounds like a problem with the video card which is integrated into the motherboard, so basically it’s a motherboard problem.
When you have a faulty LCD screen, the laptop still should work with an external monitor attached to the VGA port. Test your laptop with an external monitor? Can you make it work this way? If not, most likely it’s bad motherboard.
