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.

Byron,
Did you test your laptop with an external monitor attached to the VGA port? Can you see if the external video works properly or it has same 4 shrunken screens?
Also, when you start the laptop there should be HP logo. Does it appear in four screens too or this problem appears only in Windows?

My dv9500 has just passed 2 months after the warranty expiration. When booting up I have 4 screens shrunken for the display. I can only boot in safe mode, which I still end up with 4 shrunken screens. I think the booting up issue came after the shrunken screens started occuring. I am thinking kids and wife rebooted several times trying to get rid of the wied display. Any ideas?

Did you find a link about free HP repairs for dv9000 laptops? Did you try calling them and find out if your laptop qualifies for a free repair? Try that option first.
I am in Australia and my model doesn’t qualify…
Thanks for the fast reply anyway… I will try to get the MB from China as it costs US$550 AUD$800 unfitted here…
Cheers, Dale.

Dale,
Even though the laptop screen displays only white vertical lines, you still can see them and the LCD is bright, correct? That means the backlight and inverter work properly. It’s not an inverter related problem.
In your case both screens, internal and external, display a garbled image. Most likely you have a problem with the video card.
I’m not sure 100% but I think the video card in this laptop is integrated into the motherboard and cannot be removed or replaced separately. That means you’ll have to replace the whole motherboard.

Hi all,
I was wondering if you can help me diagnose this.
My DV9008tx is 2 years old and when turned on has only white vertical lines/panels of different shades about an inch wide across the screen.
When hooked to external lcd, t will only boot in safe mode low res and has dotted vertical lines down the panel.
Do you think this is a Motherboard or inverter? I wish to fix it myself and the MB is quite expensive….
Cheers for any advice! Dale.

Asif,
That’s what I think but I could be wrong.
Based on my experience, it feels like a defective LCD screen.
I don’t know. Different screens might require different wiring (different LCD cables).
Maybe you should search for a new replacement screen using the HP part number from the old screen? That’s would be the best way to go. Just to make sure that you buy a compatible screen.
I just searched through the maintenance and service guide for HP Pavilion dv2313cl notebook and I found that HP lists four different LCDs for that model. It’s not very clear which one you should use. Here’s the list of LCDs I found in the guide:
Display panels:
For use with full-featured computer models 430457-001
For use with defeatured computer models 430458-001
For use with dv2200 models, BV panel 435842-001
For use with dv2200 models, AG panel 435843-001
I guess you’ll have to remove the LCD, find the HP part number from the LCD, and search by that part number.

Thanks Laptop Tech,
So you’re saying that my only solution is pretty much to replace the LCD screen…? If that is the case, i have a quick question….how much does HP vary when it comes to different models (such as one being Intel, other being AMD) but with SAME sized screens…? The reason I ask is, I have the DV2000T, and I have found a replacement screen, that is ALSO 14.1 inches, for a fairly good price…this is the link
For this 14.1 model, the number is DV2313CL…I have found also another one in the DV2000 series, with model numbe DV2035EA.
So in summary…even though these LCD screens aren’t labeled for sale for DV2000T, since they are in the same product line, and same screen size, can these replacement LCDs work with my computer…?
Thanks a lot once again, I appreciate the help thus far.

Ben,
Yes,it’s possible. You can remove the entire display panel and use the laptop as a very thin desktop, BUT the wireless antenna cables are running inside the display panel and if you remove the display, you’ll loose wireless capability. On the other hand, if you use it only on your desk, you can connect to the Internet via a network cable.
In order to remove the display panel you’ll have to remove the keyboard as I mentioned in my previous disassembly guide for dv9000 series, unplug the video cable, unplug the wireless antenna cables and unscrew display hinges. After that assemble everything back together but without the display panel.

Asif,
That description sounds like a problem with the LCD screen. I think you have the same problem as it mentioned in the example 7 in this post.

The screen of my dv9000 no longer works and I cannot afford to get a new one, so I’ve just been using an external monitor. Is it possible to entirely remove the laptop screen and just use it as a very thin desktop with the external monitor?
Thanks
