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.

My Issue is that I accidently sat on my Laptop. My screen now looks like someone through a baseball at it. There is a while section that goes down the middle at the top it looks like cracked glass. The laptop is not cracked but that is what it looks like. What should I do? Thanks Everyone.

Okay so heres the deal. I dropped a glass of water on my laptop (i was trying to hold it in my mouth while carrying my laptop). I figured out that wasnt such a good idea. XD. I quickly turned it off and cracked it open hoping it would dry out. I started it up a couple days later and it works. Only thing wrong is my keyboard is freaking out (i have a new one coming). Also the screen is VERY dim. I need a flashlight to see anything. Later i took the casing off the lcd and found the inverter was very wet. So i ordered that also. If that doesnt solve my problems is there any way to get new back lights without buying a brand new lcd? that would suck Thx!

I had the same problem with the post above me and it was an inverter problem
Right now I’m having an issue with different parts of my screen flickering low, I think its a backlight problem but I don’t know really. Since I replaced the inverter recently i dont think its that but I’m not sure, if it is the backlight I need to find a way to replace the backlight on the screen.

I have HP dv9000 laptop and my screen flickers and then turns off. I can definitely see something is displayed on the screen if I look closely, it just seems that the backlight is not working. If I close the lib and open it again it flickers on and sometimes stays on, but lately if I close and open the lib it just briefly flickers and stays off.
Do you think it’s just a loose connection or do I need to replace the inverter or even replace the entire LCD screen?
Thanks, Frank

I have the HP Pavilion DV9000, and my laptop hit the table pretty hard. Not my screen is gray in color – it has light, but no color or picture. I did plug into a monitor and it showed fine on that screen. I opened the screen and it all looks like it is connected fine. Any other ideas?

Lisa,
Basically, you’ll have to disassemble the laptop to the point where you can access the video cable. The video cable connector can be found under the keyboard cover. I explain how to remove the keyboard cover in this guide.
I don’t know if reconnecting the problem will fix your problem, it was just a suggestions I would try first as a technician.

My problem is very similar to AMANDA’s (post and reply below) except mine didn’t take a header and it’s not the black that get’s red. Instead it’s the white or very light portions.
Amanda wrote: my hp dv9000 slid off my couch and now if I open it more than 45 degrees what is black on the screen becomes red. After being open only that much for a short time it can be opened slightly further. I was hoping something was loose and by unplugging and replugging it would be fixed. What should I do?
Tech’s response: It’s possible that the video cable got loose and is not making good contact with the motherboard. I would check connection between the video cable and motherboard and make sure the cable is connected properly.
Could you point me to where I can find help on checking the connection between the video cable and motherboard and make sure the cable is connected properly.
Thanks a million for such a helpful site!!!

jamey,
If I understand correctly, you are getting exactly the same problem on both screens, the internal LCD and external monitor.
If the internal and external video fails the same way, your problem must be related to the video card. In most laptops the video card is integrated into the motherboard, so it makes it bad motherboard. That’s my guess.

I tried with an external montior. After a full system restore it work for about 2 minutes and then I get the same split screen deal. I’m at a lost.
I was thinking of just getting a new motherboard.
