Screen fails

[guaro]

Hi gurus

I have this weird problem that maybe one of you can help me with.

I have a tablet x41, it works fine, but there are times when I am watching a video (like in youtube or MSN live) and suddenly the screen goes blank,well it seems like there are three color that the screen likes(red,white,black and sometimes blue)individual colors, not all of them at the same time, but I can still hear the video in the background.

What might be my problem

Thanks a bunch gurus
