Absolutely worth fixing! The circuit is fairly simple and parts readily obtainable. The symptom sounds like a shorted bridge rectifier. Someone mentioned there were multiple large electrolytic caps in parallel. Surge into those could be taxing to the amp rating of the bridge you had. Up the bridge rating by buying one twice the amperage if it fits the box. Put some heat sink grease on the flat bottom of the bridge to couple the heat better to the case as a heat sink. Check manufacturer and see if the amp ratings they use assume the bridge is mounted on a heat sink of a certain size.
