I have a Panasonic TH-42PX77U and about a month ago the picture will get all staticy (like your sorta picking up a channel with an antenna that comes and goes) but the audio is 100% ok. The video static comes and goes with no rhyme or reason. It is infrequent but sometimes the picture goes totally black, but again the audio is smooth as could be. We have a satellite so I thought maybe it was something to do with that, but the audio never falters. When the video was acting up I tried the antenna, roku, and xbox all with the same issue. I would say 90% of the time it functions perfectly fine. Any ideas what this could be? Does this mean my tv is dieing? Many thanks in advance.
