Hi,
this is my first posting of a problem on this forum and my first experience with an Apple G5. The PC - if I can call it a PC - fires up fine and all is well - but - none of the fans come on, so I am assuming the problem is in the power supply. The display also won't come on, but I suspect again that it also needs 12v DC (the same as the fans) to drive the display. I connected a separate display with it's own power supply which worked fine.
The unit finally shuts down when it gets to hot as the fans are not running. It fires back up again when you have allowed it to cool down so I would say it's "only" a 12dc supply problem (I hope).
After finding a good website on how to remove the power supply, I've finally managed to get the power supply out - what a job that was - but I don't know which pins to short out to simulate switching on the power and I don't have any information on the pin out on each of the plugs. I have had a look around on the web and found information about G5 power supplies but they are not the same power supply as the one I have which is the Liteon PA-6601 which seems to cost about £160 UK pound for a replacement.
I was given the complete unit, display and keyboard as the previous owner had been told that the power supply was faulty and needed replacing. He felt it was not cost effective to have it repaired. As this is my first look at an Apple Mac I thought it "might" be worth trying to repair the faulty power supply.
Another option would be to locate the output for the 12 DC line, disconnect it from the power supply and then connect a normal PC power supply to supply the 12 DC line to the fans and display.
Any thought on how to address the 12 dc supply problem - and - is it worth trying to fix this thing?? I'm always up for a challenge but I wander if this one is worth the effort.
Thanks in advance for any feedback, comments or advice,
Siggi
