The unit was working fine until I watched a video tape the other night. The picture went red and blue and then blank. I tried a DVD and the same thing happened after a while. Thinking it might be my TV, I started watching regular TV...nothing went haywire. So I played the tape again....the picture went screwy....same thing with the DVD.I've had it in for work before when it was under warranty but the was a year ago.....and at that time it had a different problem.
