My questions:

1- Can it be repaired and how?
2- Power function seems to be ok, can I use this powermac right now?

Thanx

ps: sorry fo my bad english

Your English is fine. I would think you're going to have to replace the logic board. There is no way you can re-solder or repair the broken pins. There are probably G5 machines around that are selling for parts on eBay and maybe even local to you. You may be able to buy one at a very low cost and cannibalize the logic board from it.

First of all thanx chscag for your answer
You have just confirmed what I thought (can not be repaired)
Destroyed pins are 6, 7 , 8 ,9 10 and 11 which are in part for audio, usb, firewire and led power.
Pin 22 for power is ok, can't I use this powermac without connecting anything?
Will it be dangerous to try?
Thanx

Probably not dangerous to try, but be careful anyway if you see smoke or detect a burning odor. And since you got it for free, you've nothing to lose.

Thanx,
I may get the ac power cable tomorrow, then I will try
I will write my conclusions then.

Hi
I plug the ac power in, push the power...nothing
After resetting SMU > http://support.apple.com/kb/HT1436, and PRAM/NVRAM > http://support.apple.com/kb/HT1379?viewlocale=en_US.....bingo, it works like a charm
Fresh Leopard install done...Simply Great
Thanx for all

Power connection

Good morning, I registered just to check on the front panel connections.
From what I noticed, the pin 22 is the Power, but he alone? Or was he and 14, which is the gnd?
In my case, I have a PM G5 in which there are only 18 pins in total. Is it the power is 18, taking reference to the drawing, 22 is the Power.
