Question
Above receiver connected to Monster Power HTS 3600,Definitive Surround sys.,Sony XBR3 KDL HD1080,Panasonic DMPBD-10,FIOS Cable Serv.DVR,Genesis mx900 remote. Problem:First heard crackling sound from one speaker then Picture would for a second go black then come back then repeated again finally the receiver went off along with the TV then came back on then off again and at that point I looked at the receiver screen and noticed before it shout down it read: AMP Error" What do you think?

Answer
On page 71 of the owners manual, it states:

"AMP ERR blinks in the display,then the power automatically switches off.
The MCACC blinks and the power does not turn on.

• The receiver may have a serious problem. Do not try switching the receiver on. Contact a Pioneer authorized independent service company for help."

I'd contact whoever you purchased the receiver from.
