EN:
Last week I took my Korg M50 to an electrical engineer to solve the freezing problem, I knew the problem and he had repaired many korg main boards and I knew the procedure. replaced two capacitors (the same as indicated on the page of korg) and made reballing in the welds. Problem solved, my Korg M50 is new again

Problema resuelto, mi Korg M50 quedo como nuevo.

I'm ordering the pieces, and I hope it works!

Will they deliver the pieces also to other parties or just to dealers?

Guitar Parts sell the replacements, so pretty much available to anyone:

The service bulletin makes the recommendation to replace capacitors with a low ESR type supplied by Korg and not substitute any other capacitor. There will be alternatives out there, but any alternative would need to be chosen with care.
