When I turn on my Yamaha RX-V657 without the speaker wire connected, it only stays on for one second and then turns off. No error is displayed on the screen. Is this normal?

You forgot to see the AVR works prefectly using speakers
8,6 or 4 Ohms Z, selected to right ohms the switch.
does it? if yes he below is moot,

why do that.
it there is sound source running, and loud and you have no speakers there, that can damage some amps.
so don't do that, some AVR have no error code, protection lamp
just relay clicks
your AVR is really old a sea of RCA jacks on the rear.
there is no need to run any amp ever, lacking a set of speakers.
7.1, does have rules here, no sure me miniumum rules.
may be 2 are required min. (the selected set A or B)
what I do is read the manual first .
found it googled in 1second flat.
page 88

The protection circuitry has been
activated.
Make sure all speaker wire connections on this unit
and on all speakers are secure and that the wire for
each connection does not touch anything other than
its respective connection
Check that the impedance selector setting is correct
ok

I have repaired amps (AVR and others back to 1960s)
the protects circuits trip 1 or 3 ways or both (tech facts)

  1. over currant the PA (power amps at speaker jacks)
  2. or imbalanced driver transistor pair (push pull or class A)
  3. or overvoltages there. now.
so if it has way 3, and he source is full volume and heavy metal band then it trips. no speakers due to output is way too high.
an amp that can do 1000w peak can do 90v peak to a speaker.
yours is 95watts RMS each , peak is not stated. nor is protects stated in absolute terms.

answer 1,. turn off all sources and volume down to run no speakers.
also it told you power off to connect. speakers.
when you do not power on the surge in the PC can be huge
so it tells not to do that.

Yamaha RX-V657

This will almost certainly be a problem with the power supply, a faulty part. Unless you have experience of repairs to power supplies, due to the high voltages, I suggest you take it to your local authorised Yamaha Repair Centre.

The receiver shuts down when zone 2 is turned on

Disconnect the speakers on Zone 2 and try to turn on the receiver again. If the receiver works, there is a shorted speaker wire, pinched wire, or a blown speaker on zone 2. Good Luck

Yamaha rx v473 cuts off

disconnect all speakers, turn it on. If it stays on, connect one pair of speakers at a time and when it shuts off, that speaker is the problem. There may be a short in the wire or the speaker may be bad. If you get that far, try connecting the bad speaker with another speakers wires.

It turns off with an error to Check Speaker wires. It's done this in the past, usual if I push the volume too it's threshold. It would always bounce back. Now it shuts down at just about it's mid-peak...

Did the fact that it was responding negatively to the loud volume not suggest it might be a bad idea to keep doing it?

The threshold on the volume knob is NOT where normal undistorted listening levels are found. Given a normal level of input you could be pushing your amp so hard that it clips or distorts and kills your speakers.

Do what it asks: check the speaker wires for shorts. Or disconnect the speakers and pray it comes back to life, then isolate the shorted (dead) speaker.

Yamaha rx-v456 av receiver, shut down with optica cable

Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.

Yamaha rx-v461 not working

you have a faulty circuit somewhere, whether its in speaker wiring, or power source, i dont know, but your reciever has an automatic circuit breaker in it for protection, and a faulty circuit will trip it, i would assume it is a power source problem since it wont turn back on, check wiring, plugs and look around, and smell for burnt, or hot components.
