I have a 2 year old AVR-391. Over time it has had strange bouts of what I call "alien chatter" where the unit starts giving me a strange alien like sounding audio signal through my speakers when I would power it on or change a channel ocassionally. Now I have a strange high pitch resinance that is coming through the front left surround speaker. I have changed all HDMI cables, speaker wires, swapped rear speakers to the front and no change. Does anyone know what can do for this aside from replacing the entire unit?
Thanks,

Done... actually made it worse as the resonance is constant in most surround modes now and more alien chatter.
