I had a somewhat similar experience with a Iici - there's something touchy
about the portion of the power supply circuitry that trickles a milliamp or
so of +5 to the logic board to enable startup. Also - does the fx PSU have
one of those push-and-lock-in power switches on the back? Iici's do and
sometimes fiddling with that will have a beneficial effect. Worth a try.
