Yamaha Receiver Service Center

Caps and rectifier bridge are the first line of defense after the fuses. If you're running a 110 v device on a 220 with a step down, you inherently run the risk of over voltage if your step down fails in a short mode.
In any case, I'd open and look for a fuse, and caps and rectifier bridge - and these dont fail silently ... they fail spectacularly. Big burnt and splattered parts.
I once fixed a realistic sta 2200 which had a rectifier bridge go. There was a volcano in the thing as per the guy I got it from. I fixed it in a few days ... pretty obvious what was dead and why and how far the damage carried down the line.
Cool.

I's told by the Yamaha service center that first line of defense should have been the SMPS, he's also surprised to see that didn't protect

No - the AVR aparently has an SMPS inside.

My RX-V679 failed to power ON. Can any of you share the service address in Bangalore. I am pretty new to Bangalore.

Got address of ARN and Thomsun from page 1. Let me try with them.

What was wrong with your V679 and could you get it fixed at Thomson?
