Hi,
I had posted earlier(#1047) that my Rx 473 has gone into standby mode and not responding to any command. I located the Service Centre "SoundRex" in Kolkata, College Street, and took the AVR to them. Found the owner Mr Rajesh quite knowledgeable and a fine gentleman indeed. He also services Denon & Marantz. And my AVR? All it required was thorough cleaning of PCBs & contacts. As I was away for nearly three months and the AVR was lying unused, lot of dust and muck( due to rainy season) had deposited which was causing short circuiting.
Sharing just in case somebody lands in such situation.

Good to know that AVR is working fine now. Covering the AVR with a cloth when not in use will help to some extend as the top vents will be covered.
