I have a g3 700 imac that hasn't been used in about a year since it died and was replaced by the intel based imac. The g3 imac will not even power up. The CRT was showing signs of degradation before the g3 quit. I wonder if it is a power supply failure or perhaps a shorted flyback transformer. Since there is no power evident, I suspect the power supply. I wouldn't mind attempting a repair if parts are available so I could use the g3 700 imac on a wireless network at home. Any advice or opinion on the problem and/or repair would be appreciated.
