My Yamaha RX-V395RDS is working well but shuts down, sometimes after an hour or two, other times at the end of a few minutes. Speaker and all electrical cables have been cheked and are ok.

First check all you speaker wiring and connections for short circuits and bad connections. Also check the speakers are working correctly.
If that doesn't correct the problem, then it's probable that an internal fault has developed in the main amp section. Till that is fixed then the amp will continue to shut down.

Try holding the INFO and TONE CONTROL buttons and pressing power. This will release the protect lock. If it shuts back off, try disconnecting your speakers and try it again. You might have a shorted speaker or cable hooked up causing it to shut down.

It sounds like it's going into safe mode try testing the resistors just after the power supply you will probably find one or two at fault

try to fasten screws at back of the unit ,
may sound like BS but if amp board don`t have good ground connection it can go in protection mode

happend to me on RX-V592

Since it comes working again, immediate solution would be

• to tone down a bit your volume, check the speaker settings

like "small" or " large"

• and see if it subsides,


if not check the main amps integrity and the speaker systems.


Speaker Systems

• These would be connecting each speaker one at a time to find

the cause.

Swap the speakers left-to-right to isolate if it's an amp or speaker problem. You have not indicated this was done.

It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.

When a system shuts down after a few seconds it is the self protect circuit shutting down power to the outputs to prevent (further) damage. It may be caused by frayed speaker wires, bad speaker voice coils, or blown output transistors. First, turn off power and remove all speaker wires from the receiver. Turn it back on and see if the problem remains. If it works OK, inspect each speaker wire at both ends for loose strands and correct these. Then, hook up your speakers one at a time until the problem reappears. That speaker or its' wiring is your problem. For safety's sake. turn the receiver off before connecting each speaker. An accidental short of the output terminals can be disastrous (and expensive).

Hey there! Nice receiver :0)
Sorry about your troubles. I've been where you are with an Rx-V2600. Would turn on and after a few seconds click off. I thought maybe it was bad wiring but even completely disconnected it would still do it.
I took it to a shop and I was told it was a bad channel. Luckily I mentioned I had a Denon receiver that had stopped working and he said he would take that as payment.
He fixed the Yamaha and it's been working for years.
If you search the internet you should find a local authorized Yamaha repair center. I would take it there. They marked charge like a $30-$50 fee to look at it but usually they apply that towards the repair.

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
