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.

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.

casey,
Usually it’s written on the LCD screen sticker (on the back).
Also, you can google the screen model number and find screen specifications.

Hi, sorry to bring this up again. Im still having the inverter buzzing problem. Also, i was using my laptop today and for the first time in a long time, the laptop’s backlight stayed on for a long time. I haven’t done anything to it and it is the original inverter that came with the laptop, but there seem to be a problem with it. The inverter is getting pretty hot, which is also heating up the entire lower part of the bezel and now that i look at the screen, i see that the lcd looks like burnt on the lower left corner. Do you know why is the inverter heating up so much?? is it an inverter problem or something else?? please help, thank you in advance

I’m having the same problem as Alfredo. I followed the instructions and the problem is situated in the cable connecting the LCD screen to the moderboard. My laptop is an HP Pavilion dv9530eb but I don’t have a clue where to find a new cable.. any help?
Thanks!

Hi, my messages don’t appear anymore, I did what you told me and the problem is the cable, please which cable do I need to buy?.
Thank you!

Alfredo,
This is possible LCD cable failure.
Here’s what you can try.
First of all, test your laptop with an external monitor. If you get same green pixels on the external video, this is the video card failure.
If external video works fine, try the following:
1. Remove the keyboard/power button cover so you can access a part of the video cable. It’s plugged into the motherboard close to the left hinge.
2. Try moving the cable while the laptop is turned on. If moving the cable affects video on the laptop screen and green pixels go away (or appear), most likely this is video cable failure. Replace the cable.

Hi, I have a Pavilion dv9000, I have a problem with green pixels. When the screen is 90 degrees position everything is ok, but if I move a little the screen the black pixels turn green. I look like there is a problem with the Display Cable Kit or something like that, please I need help. How can I solve this?.
Thank you!

Hi – I have an HP DV9260 Laptop, when I open up the screen for use, it is fine up to a point and then once it goes beyond that point the display goes haywire. The point is slightly less than 90 degrees open, and once it goes past that, the display turns magenta color and it looks like there is a short or something. Is it possible to remove the screen at the hinges to see if there is a short or perhaps maybe there is some dust./dirt inside? This problem just occurred recently. Thank you for your help.

Hi. I have a dv9000 with the same problem as some people have. You cant see anything on the screen without a flashlight, so I know the problem is with the backlight not turning on. I followed your guide and replaced the inverter but I still have the same problem. The backlight turns on for just a few seconds then it turns off, there is still image but is very dim. Also, now that i changed the inverter I notice that it makes a buzzing noise in the little time when the backlight is on, then the noise goes away as the backlight turns off, so I guess it must be related. What do you think the problem with my laptop is?? Will I fix it changing the LCD entirely or is it an electrical, maybe a grounding problem?? Thank you in advance
