Powersupply of a by lightning struck Imac mid 11.
Peter H -
Problem was (is) a dead Imac hurt by thunder/lightning... but the powersupply was one part among things that could go down by lightning, there is a logicboard-error on this imac so the powersupply did not fix is this time.
Naaa... logicboard failure.
A dead Imac could be logicboard-failure,
