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

Yamaha r-v701 just shut off one day. Im on soc security and cant send it in to be fixed so im trying to find out if it has an internal fuse that may have blown that i can replace? please help

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Yamaha v-r701 reciever It has sound but it is very faint. You have to turn the volume way up for it to play at a wisper.

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead

I have a yamaha r-v701 the main 120 volt fuse was blown when replaced it keeps blowing what would be causing the short

If you are blowing the mains fuse, you likely have an issue in the power supply. This can be a bad rectifier or filter capacitor; or, less likely, some other component. The fact that you're asking the question suggests you should not try to fix this yourself.

Yamaha RXV657 wont turn on at all. Fuse OK. Relay on "mains in" PCB not firing up. James.

check the voltage on the output transistors.
the center pins should be at +_ 60vdc.
the first pin on the left should be a half volt or so for the npn transistor and -.55 or minus a half volt for the pnp transistor.
any offset voltage will kick in the protection mode.

Fuse blows as soon as you turn it on. I disconnected all speakers and equipment and still have the same problem.

The power suply most likely has a problem. If it was the outputs, the unit would not come out of protect mode. Check the rectifier diodes for a short.

Display is permanently "off" on the Yamaha RX-V620

Sounds like the LED that lights up the display has burnt out. An easy fix, if you're not afraid to take the front panel apart and resolder a new one.

YAMAHA R-V701 MAKES BUZZING SOUND & WONT TURN ON

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
