Probably got zapped though nothing else died. It'll run for a half minute on fan setting and then shut off completely (no display, but volts at the ICs), after that it it'll erratically try to restart but won't, will die quickly. No parts are hot. I don't have the schematic, unless the one under the cover has circuit board details.
The circuit board over here: http://www.expertappliance.com/ac.html
is more than the unit.
There are only a handful of parts in it. A DIP display driver, a driver IC and a house numbered 30pin DIP that probably is the culprit.
I'd rather not buy another unit. Any ideas on what may be wrong or how to fix? That's my shot in the dark.
