Machine : 400Mhz iMac DV (Graphite)
Machine was working fine with OS 9, decide to do a fresh install
[with no OS 9], erase HD, partition, install 10.2 (with view to
install 10.3)
OS X works fine but machine hangs a few hours later. Restart it and
it does this :
Chimes, powers up (green power switch visible), sound of screen
energizing, HD spins up then about 5-6 seconds in (before anything
visible appears on screen) the machine partially powers down.
Thanks to the service manual I have checked the power supply flow -
the right voltages on the right pins (of the down converter board)
are present in the few seconds before it all seems to sag.
The machine doesn't actually go off, the power light remains on but
the power being supplied is less than the specification. Flaky PSU or
something else?
Have tried resetting PRAM, checking PRAM battery, reseating
components, resetting PMU.
Any ideas here or do I have a nice pretty door stop all of a sudden?
Cheers, Antony.
