[QUOTE=tpet|Jan 2, 2006 11:43:58 PM] We bought the PD50A recently and most of the time everything is great .. BUT we seem to be getting thin lines on the screen while watching TV. We have it hooked up through our Shaw HDTV box with a DVI cable. Some channels there is a thin purple line at the bottom of the screen and sometimes there is a snowy white line at the top and sometimes a green thin line on the right side and the left side has a yellow line ... haven't seen them all come on at once. Any ideas ... suggestions? when we watch a DVD on our Denon DVD player we don't see any of these lines. Also we have unhooked the DVI cable from the TV and plugged it into our 36" LCD and there are no lines. Is it a default in the TV? [/QUOTE] Did using component cables resolve your issue?
