Hi,
i am trying to repair a Mac Color Classic. It was working some years ago. One day I tried to start it and the machine was dead. Not a single sound or signal coming out of the cpu. I have been told that for starters i should remove the logic board and power on the analog part alone, and that doing this at least the fan and hard disk should work, unless the analog part itself is dead. I have read somewhere that psu does not work unless the logic board send some signal (coming from the keyboard); is that true?
Well, if I remove the logic board and start the system nothing happens, it behaves like when the logic board is in place. Does that would mean the analog part is dead or might I try another test ?
Repairing the analog part looks like a daunting task!
