Press and hold the 'tone control' and 'info' buttons and press power. This will release the protect. The first thing that show on the display will be the protect code to tell you why it shut down. If it turns right back off, then you most likely have a short in the amp that will need to be repaired.

SOURCE: Yamaha receiver RX-V663

Make sure you have an analog RCA audio cable from the source to the receiver. Digital coaxial or optical will not work for zone 2 or zone 3. By adding an analog cable it will not affect your main zone, it will always go to digital first. Hope this helps

SOURCE: The protection circuitry has been activated 3 times consecutively and as a safety precaution, capability to turn on the power is disabled.

If there is no apparent cause for the protection mode activating (such as shorted speakers, burning smell, blown fuses, lighting strike or mains power surges), reset the protection as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

Yamaha CX-A 5200 protection circuitry has been activated - won't power on

I would get it fixed at a Yamaha Service Centre, as you don't have the test equipment to find which failed component is causing it to shut down and protect itself.

The only thing you might try is looking for bulging or split capacitors. That WOULD cause circuit protection, because they are power stores and smoothers.

My Yamaha receiver RX v575 will not power up it has a blinking red light when trying to power up

"My Yamaha receiver RX v575 will not power up it has a blinking red light when trying to power up "
Never press power button more than 3 times. Your amp will be locked, otherwise.
(1)Download RXV575 service manual.
(2)Read P.25 to 29 to see if protection occurs.
(3)Read P.31 and follow the diag steps.
(4)If I protect, check all power transistors,two
0.22Ohm resistors and biasing circuit such as
all components connected to Q2022 of front L channel, on P.108.
(5)If dc protect, check if DC comes out from speaker terminal, opening metal cover required.
(6)If thermal protect, replace a thermal sensor.
(7)If power supply problem, ps prt, check all
power supply circuits, including regulators and
caps.

Our Yamaha RX-A730 won't turn on. It's less than 2 years old. It's plugged into the same surge protector box as other electronics and they all work fine. Is there a reset button or fuse box?

My yamaha rx730 did not powerup. The red power led had a faint flash, but pressing it caused it to flash rapidly but no display or relay clicking. trying to reset the speaker protection (button combination while pressing main did not work. Opened up the cover and remove the power supply board.
Measuring the 5.7v from the powerboard showed only 3v
Internal fuse is ok.

fixed it by replacing all elco's capacitors on the power supply board. Did it oneby one, and test it every time.
in the end it was the 47uf cap (C3708 page 137 service doc). Now5.7v is ok and its powersup again
Fix cost me 1 hour and $10 for new caps (incl shipment)

Any way to reset after "protection circuitry" is tripped three times on RX-V675?

Try pressing and holding the 'tone control' and 'info' buttons, then press power. This should unlock the protection lock. the lock is there so that the unit cannot be repeatedly turned on when there is a problem that could cause permanent damage to the circuitry.

Htr-3064 reset power on

I had a Power surge in Brisbane this week and found my YAMAHA HTR-3064 AV receiver unresponsive. Thanks to the Squish22's post, I tried the above approach, which is also listed for another Yamaha model (RX-V667) Unfortunately nothing happened. Another post suggested holding the 'straight' button as you power up to go into "advanced" menu (under DILLIGAF's post.) This also did not work.
I thought I'd try pressing all 3 buttons and powering up, which worked a treat. so here's exactly what I did:

Yamaha HTR-3064 - Protection mode reset:
  1. Remove the Power cord form mains power and wait 10 seconds.
  2. Plug cord in and turn on wall socket power.
  3. While holding down "info", "straight" and "tone control" buttons, press "main zone" power button. I got a click and it was good to go from there.
I had all of my speakers unplugged at the time and tested off the headphone jack before plugging all the cables back in again. Not sure if I needed to unplug everything, but I was about to dismantle and look for a fuse when I tried this method.
Saved me a new system / service fee. Hope it helps you too.
Thanks Squish22 and DILLIGAF for the head-start!
