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.

Kim Hutton,
Sounds like a problem with the video card. It’s integrated into the motherboard, so the whole motherboard has to be replaced.
If your laptop qualifies, you still can get a free repair from HP. Check out this service enhancement program.

My HP Pavillion dv9000′s screen is grey. The external monitor only works in safe mode and has a big grey splash in the upper left corner. The computer seems to work fine ie: wireless internet, programs, updates ect. The external monitor’s resolution is 640 x 480 and I cannot change it. (it is also and HP). Is my video card bad? Can this be fixed? My warranty is up.
Thank You,
Kim

I have a HP dv9000 and when I open the LCD lid to a usable position my screen is fuzzy. If I move the lid, usually closer to the closed position I can get the picture to come in perfect. The laptop has not been dropped, and I don’t know how to tell if the hinge it broken. Please help. Thanks!

NICK,
I guess you already tried switching video from external to internal mode using Fn+F4 shortcut, right?
1. Could be loose connection between the video cable and motherboard (you’ve already reseated connection on the LCD). Remove the keyboard bezel and try reconnecting the cable.
2. Could be bad video cable. Try replacing the cable.
3. Could be a problem with the motherboard. It’s not likely because you still have image on the external monitor, but it’s possible.

No image. it never changes when you power up the laptop. I thought it would b the lcd b/c 1) the image is fine on other monitors 2) no image at all on lcd. but i was wrong and i cant figure out what it could be.

NICK,
Are you sure that there is no image at all? Take a very close look at the screen. Maybe the image is there but it’s very faint?
Does the backlight work?

I have a dv9700. the LCD has no picture, when plugged into external monitor the picture is fine. Replaced LCD and still no picture. Any ideas?

Alan,
1. This problem is not related to the video cable.
2. Could be either bad inverter or backligth. You cannot tell without testing the laptop with a known good inverter or backlight lamp.
If you have to guess, try replacing the inverter board first. It’s not expensive and takes only 10-15 minutes. You have a good chance to fix the problem.
