Troubleshooting Power Flow/ - 3
Power Flow
Power is controlled in the iMac system by the power/analog
board. Once the unit is plugged in, power flows from the AC outlet
at the wall to the AC inlet on the power/analog board. From there,
the power flows through the main cable on the power/analog
board, to the video neck board, down converter board, logic board,
and all its attached components.
