Powermac G4 Quicksilver wonít turn on
« on: August 25, 2017, 03:19:14 AM »
Good Mormont from Italy! ;)
I hope someone can help me with my little problem. Recently I discovered a powermac G4 Quicksilver in a flea market. The psu was dead, even with the Green pin trick it wonít work. Now the thing is.. Iíve bought an atx psu, and I changed the connector following a simple tutorial on the net.. the powermac is not turning on: the power button isnít working, neither a bridge between the power pin on the mobo. The pmu battery is new. The only way I can turn the mobo on is by making a bridge between COM and POWER pin on the molex connector, but doing so wonít start the processor (the screen stays black and no chime). Iíve pulled out the processor board, but there arenít signs of burn.

Someone with more experience than me could help, please?  :-\ I donít want to throw it in the garbage..  :'(
Thank you in advance
