My Yamaha RX-V657 gose auto turn off after 1 or 2 second. if anyone Know about it please tell me

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.

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.

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.

Go into zone 2 in menu select the source you want then turn up the volume for zone 2,this should work.
hope this helps.

Do you have the volume at -5dB when listening to source 1? That would in most cases be far beyond the receivers capabilities when listening on an average loud recording from a standard source. I would guess that your source has a way to low signal.

However, i assume the answer to the question is this:
There is a way to trim the levels of each source (Input). It can be adjusted -6dB to +6dB.
Select the input you want to adjust. Hit Set Menu on the remote. Then Manual Setup -> Input Menu - > Volume Trim. Adjust up or down. In your case adjust your source 1 to + 6dB and all other inputs to -6dB.

Try this:

FIX ZONE @ SOUND - STUCK ON "ZONE 2 - FIX" 1. Press "Amp" button (right side of remote - 1/3 way down) 2. Press "Menu" button (center of remote - 1/2 way down) 3. Press "TV VOL" button (green letters) until "Manual Setup" is displayed on receiver 4. Press "Enter" button (green letters) 5. Press "TV VOL" button (green letters) until "3 Option Menu" is displayed on receiver 6. Press "Enter" button (green letters) 7. Press "TV VOL" button (green letters) until "D Multi Zone" is displayed on receiver 8. Navigate from there Hope it helps. It worked for us.

My unit turned on and off a few seconds. I try several times and no lights. When disconnecting the power supply of A / C back and does the same.

I called and spoke with Yamaha support staff (Chuck) who was very helpful. I was able to get my issue resolved hopefully this works for you too.

Couple of solutions:
1) Go into the Menu setting (Manual SetUp/Speaker Set) and make sure that you do not have Presence Speakers or Suround Back Speakers
2) Also in the Menu settings (Manual SetUp/Options/Multi Zone Settings) make sure that your Zone 2 Amplifier is set to "Int" (assuming you are not using external amp
3) Zone 2 can only accept an analog signal (not digital)... so there are two steps to this one. First, make sure that you either run only analog, or if you run digital and analog then you need to select "Analog Input" on the front of the unit. If yours was working earlier, my guess is that your input settings got switched to digital (or auto) You need to have analog set up for each specific external source (DVD, Cable/DTS, etc)....
4) This model receiver will only let you control Zone 2 with the remote control. You can power it on the receiver unit. But to select your source you have to press the Amp button, then the ** button. Then you control Zone 2 and you can toggle sources and adjust volume. (Check your owners manual for programing remote for zone 2.. think I pressed the "code" button and then 2999.)

Hope this helps... it worked for me If not call Yamaha they were very helpful.
