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.

I also have the DV9334US laptop and have the same problem was Bill. HP is of no help and the extend service warranty mentioned aboved does not apply to this laptop.
This only started happening after a cross country plane ride (my laptop was in a roller bag) so I’m wondering if something got shook lose?

I have a DV9334US laptop. The screen is blank when you boot up, but if an external monitor is attached, you can see the dos boot screen on it, once windows (Vista) loads as long as nothing attempts to switch video modes, the laptop works perfectly.
But, if you run anything which attampts to switch screen resolutions the screen will go black for approx 30 sec then you get an error regarding the video has stopped responding. Then it works as long as you don’t attempt to switch video modes again.
Does this indicate a bad display or a bad motherboard to you?

I have a DV9000 that has a black screen, no POST display and then reboots about every 30 seconds too… I’ve pulled the wireless, both HDD, both batteries and both RAM modules just to be sure and then tried just one RAM module each and it does the same thing no matter what the configuration from nothing but the battery to just one each of the HDD and RAM to everything… I even tried booting from a MEMtest86+ and still no display or change… Any other ideas??

Max,
You’ll have to remove the keyboard bezel first as I explained in the previous disassembly guide for a Pavilion dv9000.
After the keyboard bezel is removed, you can unscrew the hinge cover.

hi
do you know how to get the 2 covers off the hinges once lcd bezel etc unscrewed and removed? thanks

the magnetic switch is located at the left hinge. I am not currently looking at the switch but I am using the dv9000 to type this e-mail and recall it being rather small less than 1/2 in square or round and if I remember correctly it has wires attached that plug in to the main board maybe 2″ or 3″ in length.

Johnny,
Could be bad RAM module. If you have two RAM modules installed, try removing them one by one. Test your laptop with each RAM module separately installed into each slot.

Many thanks for the instructions on changing the screen. I have an HP Pavilion ZD8228EA and, apart from the fact that there are 5 screws each side, rather than 3, to secure the screen hinges to the cover, the procedure was identical. I found that using a magnetic screwdriver was very useful in locating the screws accurately. Thank you for taking the time to take photographs etc to help novices like me – it really is sincerely appreciated.
