Check your speaker wires and connections. This means it's short circuiting or open circuiting on the output.

Why does it say protector


It says 'PROTECT' It has sensed a fault with either the speaker wires shorted or an internal failure. Remove all speaker wires and try again. If it still says protect, then the problem is internal. Service shop repair.

check/replace your speaker wires. If a wire came loose, it will go into "protect" mode and shut down, to protect from a short circuit.

Protector


It shows protector because the unit detects a short in the amp section of the unit. You will need to trouble shoot the amplifier section and replace the bad parts. If you have no solid state repair experience, my best advice would be to have a pro take a look at it for you. Good luck
