Hammond XK2 needs repair

My Hammond XK2 drawbars suddenly stopped responding. The organ probably has only 50hours of play, so it's essentially new. Has anyone experienced this, and to what resolve?

Thanks to the Zone, found a technician in my area. Turned out to be a bad ribbon cable that had a bad ground. Added a jumper from the drawbars the ground plain on the main board and whala... like brand new.
