Camera Problem?

Hi, I currently use 2 dl.2 in a Nightclub, And 1 week ago the camera on both was working very good, no glitch nothing, I saved the cue of my camera position and thing like that, past friday I open up the dl.2 all working fine till I it my camera cue, all was screwed the image I was projecting on the screen was all mess up, there was blue,red,green line going everywhere. I hited clear, I restarted the dl.2 and did a camera reset and nothing change, and its not the cue since I tryed it without hitting my cue. I want to know, is it a Svideo Cable problem, or Something Inside the dl.2 Thanks you!

Sorry for my Bad english !
