A few years ago my beloved 2004 iMac G5 started turning itself off so I decided to put it in storage and upgrade. Yesterday I came across it in the attic and decided to fire her up again. The machine was starting up fine but it would switch itself off for no reason, I took the cover off and I saw that about 8 of the caps were badly swollen. I went online and ordered 20 x 1800uF 6.3v and 5 x 1000uF 16v capacitors. I decided to press down on the swollen capacitors (bad idea) and I managed to flatten them again.....(very bad idea).....so now when I power her up I get 3 beeps and the front light flashes 3 times then repeats. AFAIK this is a problem with the RAM, but I know the RAM is fine as it was working up until I pressed on the swollen capacitors. I also tested the RAM in an old PC and it works fine. The motherboard LED's are displaying 1 and 2. The third one flickers when the power is first supplied then it goes off. So I'm getting no chimes, no display, 3 beeps, 3 flashes on the power LED and only 2 of the onboard diagnostic lights are showing. Someone please tell me that all I've done is destroyed the Caps and replacing them will bring her back to life!
