My TV is a Panasonic TX-36PF10F 36" 100 Hz widescreen that is about five years old. I started using it with a Sony DVD player of the same age with no problems. But when I upgraded to a newer DVD player, first a Pioneer DV-656 and now a harman/kardon DVD30, the TV started having problems with handling the RGB and S-video signals from the players. Same also happened with a borrowed Denon DVD-2900. I get interference that shows as horizontal bands that flicker at the top quarter of the screen. It doesn't matter if I switch polarity of the AC plug, turn off everything else electrical in the house, use better and shorter cables etc. Could it be that newer DVD players have higher bandwidth on their video outputs and that the TV gets problems from this? I have tried to turn on/off all video filtering/processing on both the TV and DVD players with little or no result. My other RGB sources (satellite and terrestrial STB's) does not produce this problem. Any and all ideas on how to remedy this are welcome. Does anyone else recognize this problem?
