Help with ds screen.

Hi,I've had my DS for a while now and a few months ago a problem accured in the ds screen.
When i try to put the screen normal, there come like 'snow' ( the tv channel kind) on it. The game continues but the screen turn almost blank. If I put the DS in like a 45 degree angle the 'snow' stoppes and i'm kinda used to it now but it's kinda irritating.
Can anyone help me with it?Bye :)

Sounds like a bad connection somewhere.

Thanks but is there anu way to fix it?

Probably a problem with the ribbon cable or something else. Get it professionally fixed at a gamestore.

K thanks
