Technician? Korg Triton Extreme repair: Western MA

[LiquidLE]

Hello all. My like new condition Triton Extreme 61 key suffered some kind of electrical event as a result of a ground fault in some bad wiring I plugged into. My field technician looked at it and replaced the voltage regulator which was destroyed in the event, but still my keyboard isn't working.

This keyboard means a lot to me; I would like to get it to someone with experience repairing these kinds of units. I've contacted a few people via the Korg find a service technician near you function at their website. Any suggestions appreciated, also please feel free to PM me if you're a technician or know one. I'm in Western Massachusetts, in the US. Thanks so much!
