Just went to reconnect my PS3 through my Arcam A75/P80 set up and there was a horrible static noise. Disconnected the RCA's and its still there, especial bad if you move the volume control. Whats puzzling me is that its just started happening on 2 of the 5 channels. Still got my Sky HD box, cd player and tuner through three of the other channels working fine with no static, only spare channel I had was the Phono channel, this has also got a static noise coming through. Any ideas before it go's back to my local hi-fi shop(again) to be repaired? I presume it has nothing to do with the P80?
