    24" imac A1200 2111 - bad power supply

    Power supply 614-0387
    When it gets hot, you have to unplug it to get it to start up again.
    When cool, it always starts up and runs fine. Sometimes if I leave it on for a few days, it will shut off by itself.

    I know these power supplies are cheap on ebay, but I'd like to know if it's an easy fix.
    I can buy these imac's CHEAP and would like to fix them for a profit.

    Usually, it's the startup caps, C131, 132 - 33uf 35V 105° green Taicon, but these check fine, .5 ESR, most of my other new stock are at 2 ohms or worse.
    I think these are low ESR caps. I can't find any other caps that check even slightly bad, and all look fine, no leakage on the leads or swelling of the case.

    Please recommend Mfg. Types and sources for parts if you know about this problem.
