Rocky Olsson lets find out what you have tried. Make sure that you check on all of these first


I've tried unplugging for 30 minutes and powering back again but still problem??

thanks for the reply.......... got anymore idea ?


Looked like you had it figured out since you had an accepted answer that made us think unplugging resolved the issue.


Did you import the amplifier from a country with a different voltage or Phase from your own?


No I bought the amp from Australia, We have the same power here in my country....

"Protector" means that the internal power surge protector has been tripped. Unplug the hifi system for 30+ minutes to reset it.
