I have recently obtained a PowerMac G5 (Dual 1.8, Model A1047, EMC 1969, 2004), which won't power on. I have tried reseating the RAM, resetting the PMU/SMU, re-plugging the cables, swapping the battery, removing the battery then holding the power button then replacing the battery, etc. It still won't show any signs of life whatsoever. Nothing happens when the power button is clicked, not any lights or any clicking noise. I am hoping not to have to replace the PSU, as I don't have the money at the moment for that. The old battery measured at 2.4 volts, so I replaced it and the same thing happens. I am beginning to think that the front panel assembly might be broken, as there was a liquid spill on the front panel. The only thing other than replacing the front panel or the PSU I haven't tried is leaving it unplugged with no battery overnight, which some other post somewhere said might work. Any help would be appreciated. EDIT: The system was off when the spill occurred, and it has been months since that without being powered on.
