HI there,

If the various lights on the keyboard section were on, you could hear the dvd player test itself briefly at start-up, and it sounded like it was running normally but just no picture, it would be your screen that has failed.

But, if almost nothing happens at all it is one of the following:

1. Your DC power jack where your cord plugs into the laptop has come partially or wholly disconnected from the motherboard inside. (see if it feels really loose and wobbly)

2. You have a bad stick of RAM that has worn out.

3. We hope for one of the first two, but it's also highly likely that your video card has failed. This is a known issue with your model of HP.

If you are not comfortable with downloading the disassembly manual from the HP Support site and attempting major repairs yourself, then you need to take this to a reasonably priced repair guy.

Best Regards,

Marcus

SOURCE: HP pavillion dv9000 screen went dead -- black

The problem is a damage to the MB by excessive heat produced by Nvidia GPU. The only way to fix this permanently is to take out the MB and reflow the GPU with heat. You can find a video on youtube how to do it. You must take out the piece of gel between GPU and cooling unit and replace it with copper bar or penny made prior 1983 - still made out of copper. Also clean the fan. Use heat transfer paste like arctic cool - not a glue, on both sides of the penny. Install win7. Win7 does not use the coprocessor and will help to ran the notebook cooler. Install speedFan 4.40 - free utility to see what the temp is of your GPU and CPU. If you did good job it will stay around 55C. If your HP notebook is still running check the temp. If the GPU is running 80C or more it will melt the connections on the MB and quit working sooner or later.

Due to the overheating issues with the dv9000's it's more than likely the motherboard has gone bye bye. You can try plugging your laptop to a regular desktop monitor to see if it's the screen; but you would have heard it chime on if that was the case. Unless you had your volume muted before the incident. Try checking the RAM (one by one), then remove the hard drive and see if you see any graphics. If none of those work, prepare for a dv9000 funeral or punt!

Hp pavillion dv9000 lcd screen changes colour when moved


The inverter is to change the volts from the laptop to the Backlight. This wont have anything to do with it.
Im more than certian it will be the LCD cable. Proberly loose or torn at where the lid closes.
Hope this helps.

Hp pavillion dv9000 won't boot. tries to start, fan comes on, screen black and then shuts off. blue lights turn on during the process. all happens in a few seconds and loops. nothing ever displayed.


There is a Limited Enhancement Program that includes this model. If you are in the US call 1-800-474-6836. If you are outside US check the HP.com website and search for the Limited warranty enhancement Program.
This is normally a video chipset issue that is embedded in your MB. If your notebook is part of the program, hp will shoulder the repair cost for the MB replacement.
