Everything has a yellow tint. I can't fix this issue. Nothing comes up in the Apple Hardware Test. What's weirder is that when I use the flurry screensaver, all the colors show up properly. When I degauss, the colors go normal as the screen shakes, but slowly turn yellow again as the pictures stops shaking. As I was typing this, the screen went back to normal colors. It flickers from yellow to normal and back again. What's going on? Is it a bad GPU? Bad monitor? What can I do to test it? I'm on a Power Mac G5 with the default 64MB GeForce FX5200 Ultra.
