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.

AMANDA,
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.

Adam,
First of all, test your laptop with an external monitor. If external video has same lines, your problem is related to the video card and opening the screen will not help at all.
I’m pretty sure this is a problem with the LCD screen, not the cable or connection. When you get a few vertical 1-pixel lines, it’s bad LCD.
You’ll have to replace the LCD screen.

Looks like Indy Indy B had mentioned “It shows pink and green lines down the screen, and depending on how I tilt the screen, I can see. Well it worked fine for a while, but now i need to tilt it SO MUCH that i can’t even see it properly because of the angle.” – a do not share his “awesome” view on other HP Pavilion features, nevertheless have experienced just the same issue on my HP.
My question is, before I damage or break anything
, is it any worth in your opinion to open the screen lid?
Imean do you think that the lines may be a poor connection tape contact /worn out tape, or some other easy-to-fix issue? There is one, sometimes 3 1-pixel thick vertical colour lines across the screen, varies on the screen angle, they would sometimes disappear when you “bend” or “tilt” the screen gently each side in opposite direction.

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? My warrenty ran out and I didn’t get the extended warrenty

question for ya
My laptop screen is showing a split screen, a top and a bottom with both showing the same image. The screen is somewhat readable but kind of garbled. I can only boot into safe mode, I did full system restore and nothing has changed. Do you think its the motherboard or screen? My warranty is over and I dont qualify for the out of warranty fix
. any help?

I have to replace the lCD screen of dv6000 series. I am looking for the cheapest possible solution. what specifications should I look for a screen? Please suggest

What is that yellow tape surrounding the video cable (right by the sticky tape)? I inadvertantly thought that was the sticky tape and removed it as well. Doesn’t look like it will be an issue but I want to confirm that before I put the new screen in.
Thanks for the tutorial…very easy to understand.

I have a dv9000 (exact model dv9927cl). Im using it right now to write this using an external monitor as the lcd doesnt work at all. The computer physically is fine only the lcd doesnt work at all. In fact the computer doesnt even see that an lcd exists. I followed your great instructions, thank btw, and checked both ends of the lcd cable, which were fine amd the cable looks fine. any more trouble shooting i can do to find the problem. I will add on thursday I turned it on and had its lcd working and a secondary display thru svideo, i left and returned to find the lcd black. couple power off and on and the lcd returned. next day turned onand found black lcd and has never returned since. ant\y thoughts?
