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.

Hi, I’m debating taking apart my dv2000t, the 14.1 inch model, and i was wondering if i could find a source for the problem that i have. My screen blurs out completely for most parts…however, if i start playing with the actual monitor, such as gripping each side and somewhat “tilting” the screen, all of a sudden, perfect picture comes up on my laptop. Of course, as soon as i let go, the screen goes back to being blurred all together. Is this a sensitivity issue, such as some ribbon not being secure anymore, and causing this problem..? Or is it a MUCH bigger one…?
Thanks a lot guys

How do I get HP to do a “Free out-of-warranty” repair of a Pavillion DV9000 laptop ? I spent over 2 hours on the phone with tech support for which I had to pay $49, only for them to tell me that they would be glad to fix it, for an additional $299 + s/h…. I have had this machine for about 13 months and it is worthless as it sits, I find it hard to swallow that I need to spend what will end up being almost $400 to fix a $750 machine that is just over a year old ….

Tanya, you can change the setting for controlling what you laptop does when the lid is closed by going into power options, and look for the link on the left side of the panel.
Actually, as a follow up to my previous post, my problem was not with my display switch. After extensive troubleshooting, I found that my laptop was actually sensing the LCD panel movement, which made me begin to suspect the LCD panel itself. I didn’t have any issues with the image on the screen when it worked, so my focus changed to the display cable. My cable was severely crimped where it passes under the display bezel, and anyone who works with electronics can tell you that a crimped cable can cause a lot of trouble. Replacing the cable fixed my problem.
Tanya, after reading your post, I suggest that you take a look at your display cable, because it sounds to me like you just have a loose connection. If it is secure, the cable itself is about $50 bought through HP, and is an easy fix.

Stanley et al…My display quit working a couple of days ago, but flicks on and off as I move the lid up and down. Works fine with external monitor, and flickers on boot up.
Can you tell me how to change what it does when the lid is closed? Thanks. HP wants $450 for me to send it in cuz they say its the screen (not!). It’s a connection somewhere otherwise more would be wrong and it wouldn’t change with lid position, right?

There are a few posts here that sound very similar to my problem. When I power on my dv9500, I get no display on the LCD panel, however, I get video when I connect an external monitor using the VGA port. That got me to thinking, so I went in and changed power settings to do nothing when my display is closed. Now I intermittently get a display, I usually have to restart a couple times, but eventually it comes on. I am fighting with HP right now to cover what I believe to be a faulty display switch module, because it is not covered under the extended warranty enhancement they put out for a lot of dv9000 series laptops, but strangely enough, not for my model. Seeing as this may be a loosing battle for me, I pulled the maintenance manual from HP’s website, and was able to locate the suspected bad module, and will eventually replace it. As stated earlier it is located by the left LCD hinge, and is rather small. If you are experiencing the same display problem I am, and are tech savy, this is a very cheap ($60) fix compared to what HP charges ($300) just for sending a laptop in to be looked at.

John,
Find the HP part number on the back of the LCD screen and google it. Same with the inverter. The part number will look something like that: 432952-001. Could be a different one but same format.
Alternatively, you can search for both parts here. Make sure the part you are buying is compatible with your laptop.

Bill,
Are you sure the laptop screen is completely blank? Maybe there is a very faint image? Can you look closely at different angles?
Can you see if the LCD screen changes color a little bit when you turn on the laptop? Can you see the backlight at all or the screen is completely black and blank?
If you see a faint image, most likely your problem is related to the inverter board.
I guess your external screen cannot handle different resolution and because of that goes black. It’s normal.

Hi I have a HP Pavilion dv9000 and my screen was blinking like it had a bad connection, I found this site and figured I could dissassemble it,disconnect and reconnect the video line, but I didn’t loosen the bottom screws after you take the plastic framing off, and I bent the LCD..its now cracked and I want to know where to buy a new lcd and if I need a new inverter as well…thanks

My HP Pavillion DV9600 screen has a discoloration running up both sides getting wider at the top of each side. HP has said it was caused by me and that I had bruised the screen while cleaning. A bold faced LIE.
They are refusing to honer their warranty.

Thanks for the site. I just replaced my Lt hinge on HP dv9000, took about 1 1/2 hours. Instructions were great.
