Dear members. My Beosystem AV9000 makes a faint buzzing noise in standby. Hardly audible but since I sleep in that room, I can hear it at night. What can cause that sort of buzz? The TV? Or the MPAV? Or one of the speakers? I have a feeling that it is the TV but it's hard to tell. I'm not even sure whether it is unnormal. Any thoughts to share? Thanks!
Greetings,
Kai
