Display problems

Hi, I have a HP Compaq NX9010 laptop. It was working fine for around 2 years. These days I have problems with display. The display suddenly turns off, but if I see carefully and deeply, I can see the computer is working fine. Just the display. It happens if I touch the tilt of the notebook. I have just kept it at an angle and have been using it. Occassionally, display turns off and I have to hard boot the laptop. After the restart it is usually fine for another 15 mins or so depending on its mood. it is highly irritating.

Has one one any solution or any experience of this problem?

Regards
Ravi
