    I am going to try and swap out the power supply first.

    Have you tried resetting the PMU (power management unit)? Among other
    things, the PMU is responsible for turning the iMac on and off. I don't
    know where it is on the iMac DV, but the reset switch should be a small
    push button switch mounted on the logic board. I would assume it would
    be accessible through the RAM upgrade door.

    This certainly sounds like the power supply. Jiggling some wires might
    be all that's needed, but iMacs are famous for this problem. m.
