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.

@ Angel,
If external video works properly, most likely there is no problem with the graphics card.
Most likely it’s one of the following:
1. Failed LCD cable.
2. LCD screen problem.
Here’s what you can try if you feel comfortable with taking it apart. Take apart the display panel and try moving the video cable while the laptop is turned on. If moving the video cable affects image on the screen and it get’s better or worse, most likely it’s bad cable.

I put it on an external display and it looks good, had used the EuroCheck and said that the LCD Cable Failed

@ Angel,
Not the inverter, that’s for sure.
You’ll have to test your laptop with an external monitor. Can you see same lines on the external video?

My Laptop has pink vertical lines on the white parts of the screen, it could be? LCD cable or inverter?

@ Daug,
What??? What are you trying to achieve? I don’t really understand what you are trying to do.

I have removed the monitor in my HP DV9500, I still have the inverter and cable to the mother board………How can I solder, modify, adapter……to allow me to plug it in to my VGA plug on my new lap top….I find sites that say you can but no details how?

My daughter gave me her old HP dv9000 to see if I could fix it. I’ve worked on laptops before when I found out how easy it was. This one has the broken left hinge, black screen, but all the lights come on when powered up with either batt. or external power, so I think the motherboard might be okay. But maybe when the hinge broke it may have stressed the wires, plugs to display, or the inverter has gone out, since she said that was the original problem, “The screen is not showing anything.”
This is the only site I could find that actually showed the difference between the single and dual backlight since I couldn’t find anything about the 17″ wxga, and 17″ swxga on the HP site. Thanks for the great photo’s you have here. The disassymbly instructions didn’t show you could take the display bazel off without removing it from the body of the laptop. I thought it did what you showed but wasn’t going to take that chance a hidden screw somewhere might break the plastic, then I’d be up the creek because HP doesn’t have that replacement part, but does have the inverter, but not the lamps.
Thanks.
