It won't power on and it looks like something it's shorting out.
Hello, now I have to say that the problem that I have it's with a Macintosh Classic II and not a 30 SE, but unfortunately there is not way of selecting it.
Anyway the problem is that the Mac will turn on and the fan spins but after 30 seconds the fan starts to make some shorting out noises like if something is shorting out but the fan is working, there is nothing plugged in except for the crt which it cannot be unplugged since is part of the power supply board.
Also another problem is the motherboard that won't give any signs of life, now this could be all faults from the bad capacitors that there are on both motherboard and analog board...if you need a link to the video to see what does happen don't hesitate to ask I will give to u a link to YT.
Oh almost forgot there is also something that looks like an amplifier for the speaker that it was covered in oil and some kind of battery acid (no the battery hasn't leaked).
Don’t ask me why there is glue everywhere…the previous owner probably fixed just fine for make it work 1 week so he could have sold it to me… :/
Is this a good question?

Have you replaced all of the electrolytic capacitors in this computer?

@andrewsawesome
Not all of them, because the ones on the motherboard didn’t leaked and they tested good, the ones on the analog board, I’ve been told yes but these nichicon seem stock to me though, also yes before it took a while to power on and it needed some “recharging” although idk because it’s like shorting out and powering, still do you think that shorting out is a common problem with old caps?

Did you pop in a new PRAM battery? Also can you take a clearer picture of the area you circled (zoom in)

Yep new PRAM battery but nothing works :/

@imacpowpcintm - The circled component is a power transistor.
