I have had this plasma for about a month now, and in the last few days I have noticed that on digital channels including the local ABC and CBS HD channels via Cox cable(no cable card), the picture is breaking up and getting some blocks, and at the same time the audio is cutting off for 5 or 10 seconds at a time. This is happening on all the digital channels. The signal strength meter indicates a full signal.
I know the signal is not the problem, because I reset the TV, and when I did the digital channels came in fine, with no breakups for a while, but within hours started up the same problem. Also, my Mits RPTV in another room get the same channels with no problems at all.
Could this be a heat problem? There is plenty of ventilation behind the set. Has anybody else had this breaking up problem?
