Korg trident mk1

ive got a korg trident mk1 that has a problem with the programmer board klm-292 i’m at my wits end with this thing so i’m wondering if anyone knows someone that has experience with these keyboards. i’m hoping i can just send them the board, so they will prob have to have a working keyboard accessible. luckily i’ve got a working trident mk1 to test with but i think i’ve hit the repair wall.

fingers crossed
