Question about Yamaha R-V701 Receiver
The pcb relay makes buzzing sound.No power,lights or anything
Usually a buzzing relay is an indication that AC has snuck into the circuitry. 99.999999% of the time, relays in home theatre amps are DC powered. If you power the relay with AC, it will buzz . I think you have a serious problem, that requires a service tech. Is the unit under warranty ?.....If so...great. If not, then I suggest you take it to a Yamaha shop, just because thay have access to all the necessary electrical diagrams and service bulletins. It may be possible that there is a factory modification out to correct an existing production problem with that unit, that only shows up later. If so, you should be eligable for the upgrade from Yamaha. If the unit is NOT under warranty, and it requires a factory mod, you may be eligible for a goodwill repair from Yamaha. Best of luck....Rob
