...coming from TV 2 output only. TV 2 has a faint but noticable pulsing static sound that is an issue for a friend of mine. He was just installed. It's coming from a 625 on TV 2 only. TV 1 is fine as are the 2 TV's powered by a 322. I hooked up my 13 inch TV to output 2 and the same sound occurs. Does anyone know what might cause this? Is it a bad receiver out of box? Thanks in advance.
