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.

My Issue is that I accidently sat on my Laptop. My screen now looks like someone through a baseball at it. There is a while section that goes down the middle at the top it looks like cracked glass. The laptop is not cracked but that is what it looks like. What should I do? Thanks Everyone.

Okay so heres the deal. I dropped a glass of water on my laptop (i was trying to hold it in my mouth while carrying my laptop). I figured out that wasnt such a good idea. XD. I quickly turned it off and cracked it open hoping it would dry out. I started it up a couple days later and it works. Only thing wrong is my keyboard is freaking out (i have a new one coming). Also the screen is VERY dim. I need a flashlight to see anything. Later i took the casing off the lcd and found the inverter was very wet. So i ordered that also. If that doesnt solve my problems is there any way to get new back lights without buying a brand new lcd? that would suck Thx!

I had the same problem with the post above me and it was an inverter problem
Right now I’m having an issue with different parts of my screen flickering low, I think its a backlight problem but I don’t know really. Since I replaced the inverter recently i dont think its that but I’m not sure, if it is the backlight I need to find a way to replace the backlight on the screen.
July 7th, 2009 at 6:13 pm
I have HP dv9000 laptop and my screen flickers and then turns off. I can definitely see something is displayed on the screen if I look closely, it just seems that the backlight is not working. If I close the lib and open it again it flickers on and sometimes stays on, but lately if I close and open the lib it just briefly flickers and stays off.
Do you think it’s just a loose connection or do I need to replace the inverter or even replace the entire LCD screen?
Thanks, Frank

I have the HP Pavilion DV9000, and my laptop hit the table pretty hard. Not my screen is gray in color – it has light, but no color or picture. I did plug into a monitor and it showed fine on that screen. I opened the screen and it all looks like it is connected fine. Any other ideas?

Lisa,
Basically, you’ll have to disassemble the laptop to the point where you can access the video cable. The video cable connector can be found under the keyboard cover. I explain how to remove the keyboard cover in this guide.
I don’t know if reconnecting the problem will fix your problem, it was just a suggestions I would try first as a technician.

My problem is very similar to AMANDA’s (post and reply below) except mine didn’t take a header and it’s not the black that get’s red. Instead it’s the white or very light portions.
Amanda wrote: my hp dv9000 slid off my couch and now if I open it more than 45 degrees what is black on the screen becomes red. After being open only that much for a short time it can be opened slightly further. I was hoping something was loose and by unplugging and replugging it would be fixed. What should I do?
Tech’s response: It’s possible that the video cable got loose and is not making good contact with the motherboard. I would check connection between the video cable and motherboard and make sure the cable is connected properly.
Could you point me to where I can find help on checking the connection between the video cable and motherboard and make sure the cable is connected properly.
Thanks a million for such a helpful site!!!

jamey,
If I understand correctly, you are getting exactly the same problem on both screens, the internal LCD and external monitor.
If the internal and external video fails the same way, your problem must be related to the video card. In most laptops the video card is integrated into the motherboard, so it makes it bad motherboard. That’s my guess.

I tried with an external montior. After a full system restore it work for about 2 minutes and then I get the same split screen deal. I’m at a lost.
I was thinking of just getting a new motherboard.

Chandy,
Type of the screen and resolution. XGA, WXGA, SXGA, etc… Look at the chart on the bottom here.

jamey,
Test your laptop with an external monitor. If video on the external monitor looks normal, I think you have a problem with the LCD screen in your laptop.
June 24th, 2009 at 10:36 am
AMANDA,
It’s possible that the video cable got loose and is not making good contact with the motherboard. I would check connection between the video cable and motherboard and make sure the cable is connected properly.

Adam,
First of all, test your laptop with an external monitor. If external video has same lines, your problem is related to the video card and opening the screen will not help at all.
I’m pretty sure this is a problem with the LCD screen, not the cable or connection. When you get a few vertical 1-pixel lines, it’s bad LCD.
You’ll have to replace the LCD screen.

Looks like Indy Indy B had mentioned “It shows pink and green lines down the screen, and depending on how I tilt the screen, I can see. Well it worked fine for a while, but now i need to tilt it SO MUCH that i can’t even see it properly because of the angle.” – a do not share his “awesome” view on other HP Pavilion features, nevertheless have experienced just the same issue on my HP.
My question is, before I damage or break anything
, is it any worth in your opinion to open the screen lid?
Imean do you think that the lines may be a poor connection tape contact /worn out tape, or some other easy-to-fix issue? There is one, sometimes 3 1-pixel thick vertical colour lines across the screen, varies on the screen angle, they would sometimes disappear when you “bend” or “tilt” the screen gently each side in opposite direction.

my hp dv9000 slid off my couch and now if I open it more than 45 degrees what is black on the screen becomes red. After being open only that much for a short time it can be opened slightly further. I was hoping something was loose and by unplugging and replugging it would be fixed. What should I do? My warrenty ran out and I didn’t get the extended warrenty
June 18th, 2009 at 7:53 pm
question for ya
My laptop screen is showing a split screen, a top and a bottom with both showing the same image. The screen is somewhat readable but kind of garbled. I can only boot into safe mode, I did full system restore and nothing has changed. Do you think its the motherboard or screen? My warranty is over and I dont qualify for the out of warranty fix
. any help?

I have to replace the lCD screen of dv6000 series. I am looking for the cheapest possible solution. what specifications should I look for a screen? Please suggest
June 11th, 2009 at 5:42 am
What is that yellow tape surrounding the video cable (right by the sticky tape)? I inadvertantly thought that was the sticky tape and removed it as well. Doesn’t look like it will be an issue but I want to confirm that before I put the new screen in.
Thanks for the tutorial…very easy to understand.

I have a dv9000 (exact model dv9927cl). Im using it right now to write this using an external monitor as the lcd doesnt work at all. The computer physically is fine only the lcd doesnt work at all. In fact the computer doesnt even see that an lcd exists. I followed your great instructions, thank btw, and checked both ends of the lcd cable, which were fine amd the cable looks fine. any more trouble shooting i can do to find the problem. I will add on thursday I turned it on and had its lcd working and a secondary display thru svideo, i left and returned to find the lcd black. couple power off and on and the lcd returned. next day turned onand found black lcd and has never returned since. ant\y thoughts?

Jim,
You can find these instructions in this service manual for HP Pavilion dv9000 notebook. You’ll find the cooling fan removal instructions in the chapter 5.25
May 21st, 2009 at 6:03 am
Is there anything about replacing the fan in a HP Pavillion dv9000.
Thanks Jim
May 12th, 2009 at 6:14 am
Can I remove the rest of the screen case. The laptop still works with an external minitor but now the screen is just in the way.
Thanks!

I mistenly left this on the wrong blog previously. My bad. I followed your instructions about replacing the inverter on my hp dv9000 but I still get a screen that can only be displayed by using a flashlight. Any other suggestions?
May 10th, 2009 at 3:02 pm
Thanks for the useful post. Unfortunately, when I followed the instructions using my HP Pavilion DV9000, the inverter looks nothing like the one you have pictured above. Mine is twice as wide and has two plugs on the right hand side. The part I ordered from your link obviously is not compatible, so I have a useless part now. Where can I get the correct part?

Hi Laptop Tech,
The new LCD Screen its brand new! but the Laptop shuts off with the old one and the new one.! when i remove the cable from the motherboard the laptop contiuons ON and i can connect and external monitor and it works perfectlly.! what do you think it could be?
April 22nd, 2009 at 11:33 am
MasterM,
What if you install the cracked LCD screen back into the laptop, will it stay on?
If the laptop stays on with the old cracked screen but shuts off when the new screen is installed, apparently the new screen is not compatible with you laptop and maybe requires a different video cable or the new screen is defective.
Before you jump to any conclusion, test the laptop with the old screen.
April 21st, 2009 at 5:16 pm
Hey when i remove the Cable that goes to the LCD and the Inverter the laptop contious on! it doesn’t goes OFF. what this sign could be?
