Hi,
It looks like an 700/800 MHz model, yes?
My 700 MHz eMac (see this post) had this same exact problem before I was given a dead 800MHz eMac, whose power supply/analog board I decided to use to replace the one in the 700 MHz machine.
It solved the problem, but, as described in my post, it needs 15-30 minutes of warm-up time before it'll boot or reboot (it also dies in its sleep, which is another symptom I forgot to mention).
Unfortunately, I cannibalized the 700's old board, so it's a hopeless mess now (I removed a bunch of capacitors and stuff, probably ruining circuit traces and IC's in the process). It might be salvageable, but....
Good luck!
