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.

HP offers free repair for some out of warranty Pavilion dv9000 laptops.
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.

Ref Post #145 – Thank you so much for your advice! The new inverter board fixed the problem of the backlight turning off. =)

Ref: Post # 140 – Dark/Black screen issue on dv9000 – Issue was fixed by replacing bad video cable. Thanks very much.

Erich,
I think you have another dv9000 with the video chip failure. A very common failure for this model and HP even fixing some dv9000 laptop at no charge. Take a look at this post, maybe your laptop qualifies for a free repair.
The problem is not related to the lid close switch or inverter. Most likely you have a faulty video chip, so the whole motherboard has to be replaced.

Cindy,
If a know good inverter didn’t fix the problem, it’s very likely that there is a problem with the backlight lamp inside the LCD screen.
It’s really hard to give a good advice to someone who never don it before. Do not hurry. Pay attention to all details.
October 27th, 2009 at 8:18 pm
Ryan,
It’s either bad inverter board or faulty backlight lamp inside the LCD screen.
I would definitely try replacing the inverter board first.

First off, what an awesome site!
I was wondering if you may be able to diagnose my problem =)
I have an HP DV1000 laptop, just today I started to have problems with the backlight of my LCD screen. When I start it up from standby, it seems to have issues keeping the backlight on. The backlight will stay on for about 5 seconds then it turns off. I press on the switch that’s triggered when the lid is closed on & off a few times and it’ll turn back on for a few moments then shut off again. After a minute or so of doing this the backlight seems to stay on.
Any help or advice would be greatly appreciated, Thanks!

Thanks for response to post #140 – Dark/Black screen issue – its not the inverter like you said. I’m focusing on the cable now. I’ll update once i check the connection between motherboard and cable or replace the cable.

hey there,
Boy sounds like Im in the right place! I have a dv9000 series monitor went very dark while using it.. With the lights on n the room I can see shadows of whatever im doing. ( not brightness control checked that first and yes its 31 days out of warranty.
I ordered and recieved an inverter from hp and installed it. made no change at all in the display. Since this happened I have been connected to an external monitor and everything works just fine. (just a paint in the a@#.)
I have ordered a display panel and am going to replace it myself as per your instruction on this site. Anything I should watch out for?

I have very similar problems as mentioned above. I have a HP DV9000 notebook. All I get on the screen is the backlight is on, however other than that it is black. I can however connect an external monitor via VGA port and get somewhat of a picture. I can only boot into safe mode this way though and when it does boot up the resolution is at 4bit color and only 640×480. If I try to boot normally, it says windows has recovered from an error (page fault in a nonpaged area). It does a memeory dump and boots, however only to revert back to this error. I have been having problems recently with the computer not shutting off when closing the lid every once in a while too. Now when the ext. monitor is connected I can shut the lid and it stays running. Does this sound like a bad lid swith module, inverter or possibly motherboard. I refuse to send it back to HP for $400. Thanks for any help.

Mike,
I don’t think this is inverter problem because the scree works fine at some angles.
Could be:
1. Bad connection between the video cable and inverter/LCD screen. Try reconnecting the cable.
2. Bac connection between the video cable and motherboard. Try reconnecting the cable.
3. Bad video cable. Try replacing the cable.

Help – I have a hp Pavilion DV9810us (dv9000) laptop 5 months out of warranty. Screen goes to near black at certain angles (even at bios screen). You can still see that icons/programs are running. If you move the screen back to about 90 degrees (and other angles), then the screen displays properly. HP will not help unless I send in for $400. Updated bios and video drivers(no effect). Any ideas if this may be related to inverter or other screen problem? thanks

Very happy about this.
Helped me alot.
Now i have my HP working again.

Will you please you do a step by step on changing the graphics card in a dv9000 series hp laptop? I want to upgrade it but cannot figure out how to get to it inside the computer.
October 9th, 2009 at 10:42 pm
I have a dv9500 the backlight is out but, I’m not sure how to replace it. Is there a tutorial on this?
October 7th, 2009 at 10:07 pm
FASSP,
Yep, sounds like a failing LCD screen. You’ll have to replace the screen.
October 7th, 2009 at 9:54 pm
ALBERT,
Check connection between the video cable and LCD screen. Maybe it’s not plugged correctly.
Try installing the cracked screen back into the laptop. You were able to see some image on the undamaged part, right? If the old cracked screen shows image, but the new screen doesn’t, the new screen is defective OR not compatible with your laptop.
October 7th, 2009 at 9:22 pm
Kim Hutton,
Sounds like a problem with the video card. It’s integrated into the motherboard, so the whole motherboard has to be replaced.
If your laptop qualifies, you still can get a free repair from HP. Check out this service enhancement program.

My HP Pavillion dv9000’s screen is grey. The external monitor only works in safe mode and has a big grey splash in the upper left corner. The computer seems to work fine ie: wireless internet, programs, updates ect. The external monitor’s resolution is 640 x 480 and I cannot change it. (it is also and HP). Is my video card bad? Can this be fixed? My warranty is up.
Thank You,
Kim

October 1st, 2009 at 6:23 am
I have a HP pavilion zd8000 and the monitor has become full of vertical thin lines of different colours. It started with a few , now it has dozens. I plugged the laptop to an extenal monitor and the image was fine. I assume its the monitor that isn´t working well. Can u helpme please?
September 27th, 2009 at 10:30 am
I have a HP dv9000 and when I open the LCD lid to a usable position my screen is fuzzy. If I move the lid, usually closer to the closed position I can get the picture to come in perfect. The laptop has not been dropped, and I don’t know how to tell if the hinge it broken. Please help. Thanks!

NICK,
I guess you already tried switching video from external to internal mode using Fn+F4 shortcut, right?
1. Could be loose connection between the video cable and motherboard (you’ve already reseated connection on the LCD). Remove the keyboard bezel and try reconnecting the cable.
2. Could be bad video cable. Try replacing the cable.
3. Could be a problem with the motherboard. It’s not likely because you still have image on the external monitor, but it’s possible.
September 25th, 2009 at 6:41 am
No image. it never changes when you power up the laptop. I thought it would b the lcd b/c 1) the image is fine on other monitors 2) no image at all on lcd. but i was wrong and i cant figure out what it could be.
September 24th, 2009 at 9:57 pm
NICK,
Are you sure that there is no image at all? Take a very close look at the screen. Maybe the image is there but it’s very faint?
Does the backlight work?
September 24th, 2009 at 4:43 pm
I have a dv9700. the LCD has no picture, when plugged into external monitor the picture is fine. Replaced LCD and still no picture. Any ideas?
September 19th, 2009 at 1:10 pm
Alan,
1. This problem is not related to the video cable.
2. Could be either bad inverter or backligth. You cannot tell without testing the laptop with a known good inverter or backlight lamp.
If you have to guess, try replacing the inverter board first. It’s not expensive and takes only 10-15 minutes. You have a good chance to fix the problem.
September 19th, 2009 at 12:47 pm
Caled,
You don’t have to remove the LCD screen but you’ll have to remove the front bezel. The webcam is mounted above the screen.
Can you see the webcam entry in the device manager? Try removing the webcam from device manager, restart the laptop and let it re-detect the webcam.
September 19th, 2009 at 12:19 pm
BBOR,
It’s not very clear from your description if you are experiencing a problem with the backlight or image itself. Which one comes and goes, the backlight or the image?
Most likely the motherboard is OK because the laptop works fine with external monitor.
If the backlight flickers but the image is always on the screen, it’s either bad inverter or backlight lamp inside the screen. I cannot tell which one is bad because both have very similar failure symptoms. I would try replacing the inverter board first. There is a very good chance to fix the problem.
If the image flickers but the backligth is always on the screen, it’s possible that you have a problem with the video cable.
September 17th, 2009 at 12:24 am
I have a HP DV6000 laptop, the screen is faulty.
I would like to try and determine if its the LCD or the inverter or the motherboard.
If i link to external monitor the external image is fine.
The laptop screen flickers and shows the image for a fraction of a second then continuously comes and goes. Any guidance much appreciated.
