Hey, I recently got my old iMac g5 out again but it won't start. I've checked the diagnostic LEDs. Led 1 lights up when the computer is off after I press the power button led 2 lights up too and fans start to spin at full speed . But led 3 never lights up, I've used my multimeter to check the voltages on the power supply. The power supply outputs 12v and has two ground connections and a PG (Powergood) Connection which sits around 0.6V. Can anyone help me. In not entirely sure what the diagnostic LEDs mean nor how I can get my computer to start.
