Technics M3D Pitch Fader LED Doesn't Work
Posted on: 25.09.2013 by Delena Katherman
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?

Does this behavior help you target the problem more specifically?
As you mentioned, whenever you press ahrder on the reset switch, the LED activates. Then it is definitely a loose connection or contact on the switch. Since the LED lights up, then the bulb is fine. Something needs to be fixed in the reset switch's PCB.

Then the LED must be busted and needs to be replaced or a wire or PCB may have a loose connection.

So your deck is fine.
