If the power button flashes on when depressed, but nothing else...
POWER MAC G4 MDD 867MHz DP
If the power button flashes when depressed, but nothing happens... is this a power supply issue, a cable issue, or a logic board issue, or power switch/board issue?
Still awaiting input to my followup. Thanks
