don't know what kind of radio you have, but usually if a radio is flashing protect it is because you have a short in the wiring, a bad speaker or a bad output ic.

It shows protect when it senses a problem with the output wires shorted or some internal fault. Try disconnecting all the speaker wires and power up again. If it still shows protect, then the fault is internal.

the protector comes on to keep the amp from further damaging itself or the speakers. The buzz you heard was probably 60HZ line buzz from the main DC supply conducting full current through one of your speakers through a damaged amplifier transistor. Your stereo will need professional repair. The protect circuit basically opens the speaker relay (and sometimes shuts down the unit) to prevent this DC voltage and current from getting to your speakers until the problem is corrected.

wires are ok but speakers may not be which can put it into protect.other then that your head unit has an issue

The protect circuit is doing it's job....probably the amplifier
