What the heck did I do

So I pulled my platter to look at the bearing on my VPI prime. I have the eagle PSU, and the road runner tachometer that control my speed. After I re-greased the bearing I dusted the platter with one of those swiffer duster‘s and the duster went near the little PCB board that the Road Runner tach picks up at signal with. 
I put everything back together and switched on the turntable, it spins at 33.3 RPM but now the tachometer isn’t picking up any signal to control that speed. Did I statically electrically charged the PCB board and damage it?  If so what do I do now?

Last_lemming you sure you did not knock the target off the platter?
If you did not and everything is hooked up correctly then the sensor on the PC board is bad. You can try shocking it with some freon to see if you can free it up otherwise it will have to be replaced. Maybe it is still under warranty?
