All of a sudden, my HDTV which i have hooked up to my media pc has a blue tint to it. One day it was fine, the next, i turned it on to watch a tv show, and it's all blue. Tried everything, new cable, new dvi to vga converter, even hooked up the trusty MBP, and still it has a tint. Now i can adjust the blue gamma on my video card, but it doesn't go low enough to get rid of all of it. HELP ME PLEASE
