In this guide I’ll be removing and replacing the LCD screen and removing the inverter board from a HP Pavilion dv6000 laptop.
As you see on the picture above I’m fixing a HP Pavilion dv6000 series laptop with a bad LCD screen. The lower part of the screen displays garbled image and the upper part works just fine. An external monitor displays image properly. So it’s bad screen and it has to be replaced.
By the way, you’ll find another disassembly guide for the same laptop in my previous post.
STEP 1.
There are six rubber screw covers on the LCD screen bezel. You’ll have to remove all covers.
You can remove covers with a sharp object.
STEP 2.
Remove six screws found under the rubber covers.
STEP 3.
Insert fingers between the screen bezel and display cover and start separating them.
Continue removing the bezel. Be careful, the bezel made of fragile plastic.
The screen bezel has been removed.
STEP 4.
Now you can get an access to the screen inverter which is mounted below the screen.
Remove one screw securing the inverter board. Disconnect cables on both sides of the inverter board.
The inverter board has been removed.
STEP 5.
Remove two screws securing each display hinge/bracket.
STEP 6.
Now you can get an access to the back side of the LCD screen. Remove clear tape covering the connector and disconnect the screen cable from the LCD screen. Simply unplug the cable from the connector.
STEP 7.
Remove two screws from each side of the screen. These screws securing the display hinges/brackets to the screen.
STEP 8.
Now you can remove the defective LCD screen and replace it with a new one. You can find a new LCD screen for HP Pavilion dv6000 laptop here for less than $80.
The LCD screen has been removed.
The following part numbers for HP Pavilion dv6000 series laptops could be helpful to you. I found them in the official maintenance and service guide.
15.4-inch, WXGA, SVA display panel with BrightView (Glossy) 431386-001
15.4-inch, WXGA, SVA display panel AntiGlare (Matte) 431387-001
LCD screen inverter 431391-001
UPDATE: In one of the next guides I explain how to completely disassemble HP Pavilion dv6500, dv6600, dv6700, dv6800 notebooks. It should be similar for HP Pavilion dv6000.
If your laptop has no video at all, it could be the video chip failure. Take a look at this video tutorial explaining how to fix failed video chip.

mouline,
This part of your description sounds like a possible problem with the LCD cable.
This part sounds like a problem with the screen (probably faulty backlight) or inverter board.
This part is confusing. I’m not sure why the laptop doesn’t fail when running on battery power but it tells me that most likely the inverter works properly.
Here’s what you can try if you decide to fix it yourself.
Remove the display bezel, so you can access the LCD cable. Turn on the laptop on AC power and wait until it starts failing. Now very carefully touch/move the LCD cable. Does it make any difference? Can you make the video work properly by moving the cable? If you can, most likely you have a faulty LCD cable. Try replacing the cable.
If moving the LCD cable makes no different and the laptop still fails, probably it’s related to the LCD screen. I don’t think it’s related to the inverter as you said it works properly with full brightness while the laptop running from the battery.

Well after some digging I happened upon the solution..
Go to device mgr. Under usb serial controllers find ST50220 usb camera.
Right clock on webcam and update driver.
Click Browse my computer….
Click Let me pick from a list….
Select “USB Composite Device”
Voila. Works in Quickplay, Skype, etc.
Hope this helps someone else.

Kevin,
Your description sounds like a problem with the LCD screen.
Inverter doesn’t fail like that. It either work or not. I think you have to replace the LCD.

Tim,
Looks like that’s your camera.
You can try this method:
Right click on the camera in the device manager and select Uninstall. After that restart the laptop and let it detect the camera again. It should install the camera driver automatically.

I have a problem with my built in web cam on my dv6426. It stopped working. Looked in device mgr and it doesn’t show under imaging devices. Any ideas? It is a Sonix ST50220 usb. It does show under universal serial bus controllers in device mgr.

Bruno,
You need to buy only a new LCD screen. I assume the old cracked screen still lights up when you turn on the laptop? It means the inverter works properly.

Great to see a series of photos and info.
However I found some different part numbers.
screen: LTN154at07 Inverter: AS0231721C1
these may be more generic and easier to find in the web (assuming there’re correct

Reseating memory doesent seem to solve the problem, any other ideas? One other thing i noticed is that the hdd and the light next to it do not blink at all when i switch it on.
