Sony KP-61V80 TV Sound in and out issue Can't Post

I have a Sony KP-61V80 TV and the sound keeps going in and out. More out than in, also when turning the television on when its cold you see allot of white snow but in a minute or so it clears up to the regular screen but then the sound start going in and out. Help!

Signal source is cable. Also noticed that when I select Trusurround /surround the sound goes in and out the worst but if I choose Off its not as bad but still goes in and out. Also noticed that when the sound goes in and out you can see a slight flinch or movement in the picture each time the sound goes in and out.

How is cable source delivered to the TV? 1) RF (channel 3 or 4 usually)? or 2) An Audio/Video Input?

IF RF, How does audio act when you play a tape or DVD?

RF and I get the same results with the sound going in and out. I unplugged all cables/jacks to the TV (cable box, vcr, dvd and power amplifier) from the back of the TV and plugged a PS3 into the front video 2 input and I still get the same results with the sound going in and out.

Going with your original symptoms, I'd start by checking all power supply sources that are used by the audio processing areas. Confirm they are present, within plus/minus 10%, if you have a scope, confirm no excess ripple. While in there check for bad solder joints, especially at regulator ICs.
