Question about Yamaha Audio Players & Recorders
THE ANSWER (TO MINE AT LEAST) IS HERE:
As a safety precaution, when the protection circuitry operates 3 times consequently, the capability to turn on the power is disabled.
Solution (according to Yamaha service):
Plug the power cord out. Plug it back in.
Press the following three buttons at the same time for 5 seconds: Main Zone + Info + Tone Control
The receiver will open.

Hi, i got Yamaha 677 and since 1 week i got no sound from speaker,Monitor Audio BX.
Was working in the morning and in the evening not anymore.
On display showing Decoder Off and speakers disappears from display.
I did all kind of ressets, and unplugged all cables and HDMI and leave out of power...and then connect everything again, but still no sound.
Even from Radio FM no sound,only showing frequency and name of the station, i connect also my Phone via Analog and via wifi, but still no sound, it showing on display the name of the singer but no speaker .
I have the receiver since 4 years, and suddenly dont see my speakers!!
When i power on,it does make sounds like it started normaly, display on, but my speakers dont start!

Hi all, I know this is an old thread, but it helped me repairing my RX V663.
Mine switch on, but of after one second it would switch off again.
Pressing and holding 'straight' and 'audio select' followed by pressing Power On worked as some kind of override, so it would show me an 'PS2 PRT' error.
Using 'INFO' and 'TONE' combined brought me in an 'Advanced Setup', where test no. 8 would show a PS1 of 145 (OK, it's within the 110-255 limit),
but the PS2 value was L077, so I assume Low with a value of 77.
The limits for this test are 88-140, as shown on page 47 of the service manual.
It turned out to be a 7812 positive regulator on the MAIN-2 board, I could check the voltages on connector CB303 of that little board, it's accessible from the top of the Amp, it was only 1,56V
This board is a 25 cm long and 3cm wide board, attached to the main cooling body in the center of the Amp.
With some fiddling I replaced IC104 (7812 regulator) with a 1.5Amp version that had a metal cooling tab as well.
I did put insulation between it to be sure, since the original had a plastic housing, so I did not want to create an unwanted ground loop of some sort.
After the replacement the 12V came back as normal.
After that I had to perform a full reset by going to step 23 of the Advanced Setup menu.
Turn the knob to select 23, then press one of the 4 audio field select buttons, it will show Preset RSRV.
Now power of the Amp, all done.

Can you be a little more specific about what the fault is and what you are trying to do? Is the machine constantly powering off?
The reset functions are in the ADVANCED SETUP menu which can be accessed by holding down the STRAIGHT button while you turn the power on.
If you can give more specific details about the problem, it will be easier to determine what might need to be reset - rather than resetting the whole unit.

SOURCE: How do you reset the
If you are referring to "protect mode", there is no reset. See the link below for an explanation of protect mode. Specifically for your unit, should you find that the outputs are defective, you can expect a parts cost in the $50-$70 range for the repair. Please update this with any other questions you may have.
