I m Vijay From Malaysia, I M looking for Yamaha RX-V661 service manual does any one has this manual. My problem is cannot switch on. I have check the power transistors, Capacitors and main transformer everything seems OK.
There is power to sub trans but the relay doesn't energize for the main transformer so there is no supply to the main transformer.
I have been repairing amplifier's for some time, but this is bit funny, something is blocking the signal to the relay.
I have heard this is a common problem for Yamaha AVR Amps.
Any idea or advice much appreciated.
Thanks a million,
