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?

Why did you feel a need to just look at the bearing?
Do a once a year lube/cleaning.
