This just started today. When I change channels, the sound has a low buzz- hum that fades. When the fios is off, the tv doesnt do this.

OK. It only does it as long as the info is flashed along the bottom of the screen. As soon as the info dissapears, the humming stops. Its also does it when I bring up menu or guide.
sounds like an audio cable might be touching a power cable in the back, make sure your audio is securely plugged in, and that they aren't sitting on power cables or anything.
