Well the new power supply didn't do it. The G4 just sits quietly and
just makes a faint clicking noise a few times or so til I turn it off.
Haven't really been following this thread, and don't know exactly
what iMac you have, but....
Did you replace the PRAM battery? Physically replace it with a new
one. Don't just check its voltage - quite often lithium cells give
good voltage readings, but they're actually so weak they can't carry
the load.
Then reset the PMU.
Must be the motherboard.
Perhaps. Or it could be the Power Manager needs rebooting (see above).
Also... Have you disconnected all the peripherals, both internal and
external, and pulled the memory? The idea is to boot the stripped
down machine and see if you can get proper error beeps out of the
self-test run by the PMU. Once you get that much, start plugging
things in one at a time.
