Take the back cover off the machine and examine the 24 cans (capacitors) for swelling and/or corrosion. This does not sound like an inverter issue.

Sure enough, 6 of the cans are swollen and corroded. I have since learned that this iMac suffered a power surge from a nearby lightning strike in the neighborhood.
