I think your problem all boils down to electronic problems inside the monitor. It could be a million and a half different things. There are electron guns and stuff inside the monitor, that hold all the colors steady and whatnot. If you have an extended warranty plan, I suggest using it and get tthat beast fixed. If you dont, I'm sorry to say, but it would be easiest, best, and cheapest to just shell out the dough and buy a new one.
