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.

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

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.
