Hi! I own an 8 years old Korg M3 Xpanded with EXB-Radias in it and about two years ago the power supply burned. Instead of buying another one I had the stupid idea of just getting it fixed at a cheap electronic supply place.

After that the keyboard got really unstable, sometimes it turned on and sometimes it didn't and after a while it just didn't turn on anymore. I took it to a proper service center and had to spend around one grand to get all of the screwed boards fixed and a new power supply.

Now the keyboard is working just fine but some of the patches from radias have a really annoying high pitched ringing sound to the point where I can't use these patches at all. I didn't take it to a service center as I'm in small city now and would have to travel to get it to one, but I called one and was told it can be partially burnt which is unfixable. I'm thinking that's probably the case but I wanted to make sure it can't be fixed.

I did some research on google but I couldn't find anything about this. Do anybody know if it's a simple problem or if I really lost my board?

I'm really frustrated right now, all of this could be avoided if I had just bought a new power supply when the old one died. Anyway, if there's a way of fixing it please let me know guys!

Thanks!

Hi,

Repost your question in the M3 group. It is rather a M3 issue. So higher chance to get an answer.
This group focuses more on standalone Radias boards.

Good luck!
