Question about Yamaha RX-V1000 Receiver
Normal 0 OK, I have a Yamaha RX-V1000 that has started to buzz intermittently through the speakers……sometimes its loud, sometimes its quiet, and other times the receiver just simply shuts down as if it were unplugged. It’s not a hum, it is defiantly a buzz sound. Sometimes if I place my hand on top of the receiver it gets quiet, other times it causes the receiver to shut off, I have opened it up and blown it out with the air compressor, it looks clean with no burnt components on the PCB’s….I do se the power supply board behind the transformer, it does have Two large capacitors on it I assume those are the filter capacitors, I am OK with a soldering iron and could attempt to replace them, just not sure if this is the problem or not. What do you guys think ?????

This could be the indication of an open resistor, or bad Capacitor in power supply. May not be visible to eye, but if you look in PS. there should be atleast one big sized cap and every PS has a bridge rectifier, this is usually 4 diodes in series, check them and see if any open, shorted

SOURCE: very loud buzzing from speakers
check all connections to and from the amp. have you got animals in the house. They can accidenty pull plugs while exploring behind your units.
