I have a Yamaha P 26 direct drive, I let a friend borrow it & when I go back over a few days later, he says "it don't work". What it's doing is when you push the play button or lift the tone arm, the strobe lights up but the platter will not turn. It's not locked up, you can spin it freely by hand but that's it. Any help could be greatly used. I'm new here and look forward to hangin around.
