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.
