I have tried replacing the battery and resetting the cmu. The front startup button will com on then go off. Is it possible the power supply has gone bad? If so, do you sell replacement power supplies for the G4 desktop computer?
Es esta una buena pregunta?

If there is no fan activity, and reseting the PMU/Cuda does nothing, the power supply is dead. You can find replacement power supplies on eBay. Also, if you buy one, I recommend buying a Samsung-Made unit like this one, they are much quieter than the AcBel units that came in earlier MDDs. AcBel units like this one are relatively cheaper, but very noisy.

Open it up and try pressing the small button (cuda switch) on the logic board. Are you getting a red light on the logic board?
