    Hi All,

    I'm after some help here with my Denon 2805 AVR that's been very good to me. I'm getting a random occurrence when changing between TV channels and recorded programs on my Sky+ box. The receiver emits what I can only describe a loud whine from the attached speakers, Kef 5005's with the sound from whatever I was watching cuts out. I have tried disconnecting the source and speaker cables and reattaching but the random event is still happening. My current workaround is to disconnect the kettle lead from AVR for a few minutes and powering back up. Trying to change sources e.g. to my PS3, once the noise starts has no effect. It would appear that the Sky+ box has triggered the AVR to do something that causes it to kill off audio input from the Sky+ source and produces a signal that to the speakers and my ears are a loud whine; adjusting the volume control on the AVR has no effect either. If it's any help the Sky+ uses optical out to connect to the receiver.

    Does anyone have any ideas about what do to next besides the obvious replacement ?
