Question about Apple Power Mac G5 Desktop
Recently I replaced the power supply (blown) from my G5, after that is shows an unpredictable behavior. It is running great for a week, all of a sudden it shutdown the video, ramp up the fans, front white led on. When you reboot, front led light up but turns off quickly, fans start, gongs but suddenly you can see front led turn back on and simultaneously a red led deep inside the machine (not the leds close to RAM) and video never begins and stays there until fans ramp up after a couple of minutes. All leds close to RAM off.
Ran Apple Diag disk and passed all, but when you try a thermal calibration it says either radiator pump error, or to remove/replace clear plastic door.
What could it be?
In G5 always the cover should be closed properly if not it will start the fan very fast like a blower and the red leds will be on showing that the heat is over so please check that the cover is closed and locked from behind so itworks smooth and the power supply is standard or normal
u should always use genune parts with mac..
