Dead Screen?!

[russianmafioso]

Okay, so recently, i've been noticing a sort of rainbow-like discoloration on my screen that occurs on the very top of the screen. It cannot be seen looking directly onto the screen, but only from an angle. Initially it started in the center, but now it basically encompasses the whole screen. And if i run my thumb over it, it does change colors and move around and change patters. So... why do i have a dead screen you may ask? Because the screen is almost entirely and absolutely unresponsive to my touch. but if i try to manipulate it using the keyboard or buttons it works fine.
