XPS display flashing colors

I have a Dell XPS M1730, which just recently started flashing Red/Blue/Green/White/Black for the entire screen.  It will just repeat between those colors, when it happened I could still hear the sound of the program I was using at the time, so the computer itself was still working.  Just the display was gone.

Only thing I can think of is an issue with the video card.  Has anyone had this happen to them, and what was the solution?
