Re: [korg_mono-poly] Mono/Poly doesn't turn on. (Transformer gets really hot)

2009-11-27 by Chase Smith

Damn it, nevermind. One of the fuses is blown. I don't have a spare right now to replace it so I can't see for sure if it is okay, but I feel more relaxed now.

So even if I replace this fuse and it seems perfectly fine, wouldn't a fuse blowing be indicative of a problem? There wasn't really a power surge as far as I could tell and I think this fuse is only a few years old.

Thanks,
Chase

Hello.

Just a few moments ago I was playing some music and all of a sudden my mono/poly stopped working. I tried to flip the switch and nothing happens; no lights or sound. (I didn't see or smell smoke)

I opened it up and the fuses are all fine, but the transformer was so hot that I couldn't keep my finger on it for more than a moment (even now, 15 minutes later it is still very warm).
I used the service manual and checked on board 356 for voltages and none of them registered(5, 15, or -15).

I'm not sure what to do now. I'm guessing the transformer died, but how can I know for sure? What would cause the transformer to just go out like that? If it is the transformer, does anyone here have a spare or know where to find one?

Thanks,
Chase
