Incearca asta: Hold the left preset button (<) and the bass (+) button and press the power button and then release.
The receiver will disable the power protection and turn on in self-diagnostic mode.

Va multumim o sa incerc metoda asta

Well done!
Cred ca ar fi foarte util un topic cu tip&tricks echipamente electronice dupa marca.
Astea mai noi au diferite combinatii care te scutesc de multe cheltuieli.

Am nicercat asa cum ati spus si a Pornit si am ascultat Muzica a mers foarte bine. si dupa am oprito si am lasato in pauaza  si cand am Pornito mai spre seara a intrat din nou in Protectie. ce ar mai putea fi ?

Posibil probleme cu boxele.

In pauza am lasato fara Boxe.

si am mai incercat motoda asta. Hold the left preset button (<) and the bass (+) button and press the power button and then release.
The receiver will disable the power protection and turn on in self-diagnostic mode.     dar nu mai iese din Protectie

Va rugam sa mi spuneti ce sa mai fac ?

La o mica cautare am gasit asta :

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.
