hello tried starting my Powermac G5 dual 2,5ghz mac. I had given up on this for almost a year. Here's what is going going on and what I tried. I rebuilt the LCS with new O rings and new coolant. I tried booting with ram and video card out but still got the same result. The white power button LED does not stay lit. It boots with no chime, and the fans eventually ramp up after awhile. The battery is at 3.6V. Tried the pmu reset. I tried a different power supply and another LCS/cpu combo as well. I may try a different logic board, but would rather not. Went through this and other forums and tried other tests with the same result. There are no red LED's lit up on the logic board. Any thoughts?
