I can't quite tell but the capacitor could be swollen and shorted. The 3 terminal voltage regulator is above that capacitor attached to the aluminum plate heat sink. Those are the main components of the AC to DC power supply and if one of them is shorted, that could kill the power transformer. ^_^ TDD |
