Aztec LC PSU still ticking after recap

Recommended Posts

I just recapped an Aztec PSU from a Mac LC, and when I go to turn it on, it just ticks. The solder connections look fine, is there something I am missing?

 

The voltages I am getting are: ~4.5 from the blue wire, ~1.25 from the yellow wire, and ~.60 from the orange wire.

Are you plugging it into the board when your testing it? It must be connected to the logic board?

Yes

 

 

That. and make sure none of your rails are shorted to ground. 

Hmm. All colored wires show continuity with the two black wires. I don't see a solder bridge anywhere....

I have tested the optocoupler and it seems to be fine (unless I tested it wrong?).

 

I guess it never hurts to try. The model is CNX82A, Mouser and Digikey do not stock it, but I found some on eBay.

It was audible from several feet away. If you want it, I'll send it to you for the cost of shipping, shoot me a PM. Better someone make use of it than it being trashed.
