I have checked all my cables.  Tested other electrionics in the inputs and they work.  When I went to turn on my Xbox this morning I played for a couple of minutes and the screen goes a little green so I turned off my Xbox.  I turn it back on and I get purple dots moving from left to right.  What do I do?

If the cables fail would my lights go red at all?

This may be a bit clearer. I just tried hooking my Gamecube through the same inputs and the Cube worked. My Xbox has all green lights on the system and power supply. However I have no picture other than purple line dots that race across the screen. The Red and green wires when plugged in show no sign of problems but when I go to plug in the blue cable I begin to see the purple dots. Could this be caused by a short in the red/green/blue cables?
