Reply to Technics M3D Pitch Fader LED Doesn't Work

I just bought an M3D that runs like a champ and sounds like a dream, except that the pitch fader LED never lights up when at 0%. Not a huge deal, but how hard is this to fix? Could it be something more complicated than simply replacing the LED?. And finally, is there anything special I need to know since it's an M3D, or will MK2 tutorials be just as relevant?
