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?

1. Check to see if the little magnet is still there. If it is, make sure it is properly aligned with the sensor.
2. You might have bumped or otherwise slightly moved the sensor when you removed your platter. It needs to be very close to the platter.

All is good. It just started working again. I have no idea why. 
To answer some quesrions i’ve been trying to figure out why I’ve been having woofer pumping (Subsonic stuff) with cartridges that should work with the arm. I’ve checked the platter, it checks out, I checked to make sure the TT was level and check that it’s secure, I’ve checked everything I can check and all was good, so figured I check the bearing and at the same time lube it,  and that’s why I took it off.
