I absolutely love the picture on my Samsung 841 but last night when we tried to play a movie the blue screen just flickered on the DVI input on the tv. You could hear the audio fine but the screen flickered. I wound up reinstalling the DVI cable on both ends and got out the composite cables and hooked up the DVD player again. After 30 minutes of messing with it it finally came back on. When I would select DVI it would go out for a around the 10 second time frame and come back up S Video. It finally wouldn't come up at all on the composite input and I switched it to DVI and it was back on working better than ever. What would cause this to happen? Is there something I need to do to prevent this? Could it be the cable? I am using the one that came with the player. Any help would be greatly appreciated.
