Hey Mars,
What vintage is that iMac G5? If it's some of the early models prior to mid-2005, it may be the internal power supply unit. If so, check to see if Apple still covers it under the Repair Extension Program for iMac G5. I don't know when the expiration date was for that.
I remember back when I was a bench technician for a mom and pop Apple Retail and Service provider, I would get an awful lot of these in with the same symptoms or worse; the PSU literally burned up (scorch/smoke marks on the outside metal casing, with an odor that something inside was burning). I replaced more PSUs and logic boards on those than any other model.
