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 there,
Firstly thanks for posting this guide, hopefully you can help! I have a DV9565 (DV9000) and have some flickering horizontal lines on the screen as if the images (HP Logo etc.) are being stretched (streaks). I have read all the posts and plugged the laptop into an external screen and it works fine so i think it may be a bad LCD/ Video Cable. It has been dropped and there is a crack in the top right corner of the LCD lid.
Occasionally (with the power lead plugged in) the laptop will start fine with no issues at all so maybe the LCD screen is actually OK but when I take out the power cable and run the laptop on the battery (fully charged), the screen reverts back to the horizontal lines again and seems to darken a bit. Plug the power lead back in and the lines go away again!
My question is do I have a bad battery too? Is it not dispensing enough power? I purchased this laptop 2nd hand so i don’t know how old the battery is. I don’t want to throw money at this thing as it will kind of be uneconomical but don’t want to throw away a laptop that has a good motherboard/video card either.

Hello, First I would like to thank you for taking your time to publish this information; hou are providing a great service (I plan to thank you monetarily as well if this info helps me fix my notebook!)
I believe I have a cable issue with my dv9700… Recently when I open/move the screen on my notebook the screen distorts, becomes unreadable and freezes (ie, cursor will not react/move etc). If i carefully position the screen just right everything is fine, but it is becoming harder to find that sweet spot where it works.
Does this sound like a cable problem to you??
Also, I do not see in your procedure, how to access the other end of the cable; do you have to disassemble the lower case to access the main board to replace the cable or is it accessible with only the screen/bezel removed?
thank you in advance for your help!! its greatly appreciated (and will be rewarded)

Thank you very much for posting this page. I have an HP 9000 laptop and the monitor went dead. I had a computer fix-it friend look at it and he thought maybe the backlight was wrong, maybe the video card was bad (looked weird when using external monitor – no red colors).
Was looking into new laptop but gave this one more chance. Found your site by accident when googling the laptop problem. Saw your “how to” on opening the monitor panel. When I got it open, the inverter was simply unplugged. Works pretty well now that I plugged it back in!
Anyway, thank you very much for your detailed “how to”. I can only hope that someone else can find such an easy solution by using your directions!

jimmy,
If I understand correctly, you have two following complaints:
1. Laptop screen display solid white color with thin vertical line. After a while the white background fades to black.
2. When you test your laptop with an external monitor (while internal unplugged), you see lines on the external screen.
So, both the internal screen and external monitor show bad image. This description sounds like a problem with the graphics card. There is not much you can do besides replacing the motherboard. By the way, HP Pavilion dv9000 series notebooks are known for its graphics card problems.

I have a rather odd issue with my HP Pavillion DV9000 screen I’d love your advice on.
At the end of December (in the last week of my warranty period), I returned my DV9000 to HP for warranty service to replace my screen due to three areas of dead pixels. I received my laptop back, and from the somewhat limited information I can gather (from the checklist on the accompanying paperwork), they replaced: system board, display, lcd cover, top case and the display printed circuit assembly.
Now, the system has no dead pixels BUT I see three pretty serious problems with the display:
- Luminance diminished. Even at full brightness via software controls, my hardware calibrator (i1 Display 2) measures the new display at 60 cd/m^2, where the old display regularly measured at 100 cd/m^2. The difference is quite obvious. Both displays were single-bulb panels.
- Severe green color shift. Uncalibrated, the new display has a very sickly green tint. After hardware calibration, viewing the icc profile, the green curve is obviously aggressively adjusted down, and by pulling out so much green, the perceived screen brightness drops even more.
- Exteme off-axis color shift, almost as if there is a strong polarizing lens in front of the monitor. It’s so extreme, in fact, that you cannot view the entire monitor at one time without noticing color shift on one side or the other (you move to the left of the monitor and the right side shifts, move to the right and the left side shifts, etc). There is also a noticable diagonal dark band across the display which follows your position relative to the viewing angle (wherever you view the monitor straight-on, the monitor has a dark diagonal band across the display — if you move left and right, the band follows your position — almost as if you were rotating or tilting a polarized lens).
So, my question is — what should I do?
I really doubt I’ll have any luck getting anyone on the phone at HP to actually understand what any of my analysis means, and if I just tell them “it looks really green” I expect they’ll try to talk me through countless scripts dealing with software adjustments, etc.
I don’t know if now that I’m outside the warranty they will take the unit back for repair (assuming I can even get someone to agree there is something to repair), and if they do take it back, I have no idea they would have the equipment to actually test the luminance output or color shift to really troubleshoot the issue.
I almost think it would be easier to just start replacing things on my own. What would cause such a radical drop in luminance and extreme color shift? The panel itself? The inverter? The system board itself?
The apparent polarization issue makes me think at least *that* issue is with the panel itself — I wonder if I just got a lemon? (Or I guess it would be a lime in this case…. ’cause… it’s… green…. yeah, okay that was funnier in my head…)
Thanks for your great article here. Any ideas or suggestions would be appreciated.

Debra,
You can replace just the LCD screen. The webcam and mic are not part of the screen.

Only my screen is damaged. Must I order a replacement with the webcam and mic or can I just replace the LCD?
Thanks!

Sir,
My wife has a DV9000 laptop that had been dropped by a 5yo. The hinge appeared to be broken and as open up the unit to prepare it for new parts I inadvertantly broke the display. The video still works, though I do not care to continue using the display as it is cracked all the way across. I am not sure of the exact model number as I am overseas and have been watching prices for DV9000 screens.
I have recently come across a new display on Ebay that is identified as a DV9000 display, but the part number is different. Are these displays interchangeable between the 9000 series laptops? I don’t want to waste the money for a display that I can’t use.
