I turned on my TV tonight and it had grenn lines all over the screen. All inputs involved. I turned the tv off and back on again and the lines were still there. So I unplugged the tv from the wall and waited 2 minutes and plugged it back in and the lines were gone, everything was fine. What is going on? Will it happen again? I have a warranty on this. It's only 5 months old. Is it the digital board or the DMD Chip? Thanks!! Also , I think it made a weird sound when I turned it on but can't really remember because I was not paying attention.
