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.
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.
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.
Static electricity can kill your laptop. I recommend wearing an anti-static wrist strap while working with internal parts of your laptop.

Dear Laptop Tech,
Thank you very much for your helpful response and for the great tutorials on your site.
As you suspected the problem appears to be a faulty video cable, the video cable has been damaged where the laptop hinges. I have a replacement cable on order and after re assembling the laptop (with the cable in a slightly different position) my problem appears to be temporarily solved.
Although I will be glad once my new cable has arrived and is in place!
Thanks again,
Lloyd

Lloyd,
If the laptop works fine with an external monitor, most likely the motherboard/video card is good.
You said the screen works fine at certain angles and most likely this is somehow related to the video cable.
1. The cable could be loose on one end. Try reconnecting the cable on both ends. Reconnect the cable on the motherboard and back of the LCD screen.
2. Could be defective cable. Try replacing it with a new one.
3. There is a chance of bad LCD screen.
This failure is not related to the inverter board. The screen is still bright, so the inverter and backlight lamp work properly.

Robert,
Can you still see a very faint image on the screen when it goes black? Look very closely.

I have a hp Pavilion DV9605ea (dv9000) laptop about 6 months out of warranty. At certain angles I get green pixelation/fuzziness, but In a more close position the screen displays perfectly. The distorted image appears to effect video files and images most. Otherwise the laptop functions normally.
I have tried with another LCD screen, the second lcd screen displays fine until I boot into my operating system (Ubuntu 9.10) at which point the second lcd screen loses its signal. I suspect that my os, Ubuntu is not set up to support a second display.
Any ideas if this may be related to inverter or something more serious?
P.S. Thanks for the great site – your instructions on dismantling the DV9000 are extremely useful.

I have an HP Pavillion DV9408CA, the screen goes black and occassionally it comes back. Implies lose connection someplace. What would be my best route of action to resolve the off-warranty issue? Rather not plug in to a monitor as this ends the portability. Your assistance is greatly appreciated. My repair experience is limited to desktops but still knowledgable enough. Thank you

cindy,
Did you replace just the LCD screen or the entire display assembly (LCD, inverter, cables, plastic parts…)?
If you replaced just the LCD screen but still no backlight, most likely it’s a bad inverter.
I don’t know what this error means.

Ryan,
You are welcome! That’s why you replace the inverter first. It’s not a difficult repair and there is a good chance to fix the problem.
