Hi everyone!
I have now, a third in my Mac PS series.
this PS comes from a PowerMac 1Ghz G4 Mirror Drive computer.
Sadly, this one appears in the worst shape, as compared to the others which required simple low voltage recapping to regain functionality.
This PS is a Samsung 360W PS (see pics for exact info)
Symptoms: Computer wouldn't cycle, so I pulled out the PS, and opened it up (much easier as they didn't use those stupid anti-tamper screws with the protrusion in the middle of the Philips socket - good thing I have a Dremel!).
Noticed a burnt fuse, and thought, oh! could it be that simple?????
Bought some 250V 8A fuses, popped one in, and, "Pop! Fizzle! Light! Stinky!"
Hrrm...well, that's not good. I took a look and discovered a nasty burn spot right near the AC in point. I've detailed this in several pics shown below.
So, my questions, being a non-electrician:
1.) What do you think happened?
2.) What are those two components? Is the yellow a rectifier, what's the green one with a burnt "whole" on top?
3.) Is this fixable?
4.) If yes to (3), what are your suggestions? I guess I can get replacements online, as I have with capacitors.... right?
Thanks, guys.
