I have a HDTv ready plasma tv the audio is going off by its
self and on again by itself.
I've check the mute button and its on disable
I've change the setting for external speakers and the sound goes off by itself for a long period of time and then it will start again. I have Tivo and it does it with recorded show as well.
Nope sorry to tell you , the sound processor circuit has a fault and unless its under warranty be prepared to spend a hefty 400 to 600 bucks for the board.. Its not a set you can service unless you have the proper jigs and equipment. that why when i say buy an extended warranty on these sets, LISTEN TO ME!!! dont listen to a person who hasent a clue what it takes now a days to fix a plasma or a LCD tv set.. Good LUck
