Hi there, I have an I-mac G5 Duo Intel 20’ which I bought in February 2006. Apart from some minor wear and tear this still works well until last week. Last Friday I came back from a 1 week vacation (during which I had unplugged my Imac G5 - which I gather is not the best idea). When I plugged it back in there was a blue flash at the socket - like it had shorted. When the Imac then didn’t power up I initially assumed the fuse in the plug had blown. However after changing the fuse, there was no difference. I tried other sockets and it was the same story and just to be sure I tried the fuse in a working item and it was fine. Reading through Ifixit it seemed likely that the iMac G5/Intel Power Supply needed replacing, so I ordered that along with the various recommended tools. These arrived yesterday and I spent a LONG night working on the computer and replacing the power supply. However the i-mac is still as dead as a doornail. Today I got a replacement lead - incase the lead was at fault. Still no joy. What can you suggest? Although most of my important files are backed up to hard drives I really need to bring this old beast back to life. best Tom
As to your question on changing the hard drive to a different machine: You should have no problem with that as long as the programs were running OK before the old machine went down.
You’ll likely need to replace the power supply. I suspect the caps used in the PS was part of the Capacitor Plague
