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

la semana pasada lleve mi Korg M50 donde un ingeniero electrico para solucionar el problema de congelamiento, el conocia del problema y habia reparado muchas main boards de korg y conocía el procedimiento. remplazo dos capacitores (los mismos que indican en la pagina de korg) y realizó reballing en las soldaduras. Problema resuelto, mi Korg M50 quedo como nuevo.

I've opened my M50 but there are not that many connectors, and the one from the display are not disconnectable. Which connectors exactly did you reconnect (and what do you mean with 'turned around connectors to make more tension on wire harnesses'?

What I did was disconnecting all these white plastic plugs (connectors) on left and right PCB's (printed circuit boards) then I twisted each wire harness making one full circle, then I plugged them back. I didn't touch anything on display. By twisting wires there is more tension on these plugs.

• unplug<br> twist<br> plug again<br>

Just do it one by one so you don't mix them up. I hope I helped?

I just registered to say that THIS is gold and this worked for me...as simple as that...just take unscrew the back and unplug, twist and plug in the connectors from the centre panel. GOLD! Thanks so much...after about 5 years of not knowing what to do with it it's fixed![/img]
