Hi..normally protection cause by short circuit at low voltage power supply..pls locate 2 voltage regulator IC =====> 5V & 12V and check with multimeter..Normally ragulator have 3 pin...Pin 1 is input voltage..Pin 2 is ground..and Pin 3 is output voltage..check with multimeter ohm 1k===>Pin 1 & 2, Pin 2 & 3...If short that mean ragulator need to replaced..Good Luck..
