My N800 screen starts to vibrates/jerks intermittently 2 days ago. And today, it get worse -- the screen even scrolls by itself. It seems to be a problem in idle state. If I run some program, I hardly notice the problem. But if the screen stays still (not changing), then I can notice the vibration (and scrolling) problem.

Is this a software or hardware problem?? Anybody got any solution please?

Thank you!
