Good luck with it

hi, seeing that your kenwood showed up "protect" you may have an audio circuit/amplifier fault within the unit. try resetting the unit to see if unit comes "on" again. if the unit comes on and protect flashes again, then you definitely have an internal audio circuit fault. if not then check all power connections(yellow and red wire voltages, as well as ground connection), as well as the condition of the face pins!
