i turned my car on today and drive for about5 minutes before i realize the odometer display isnt on has anyone ever heard of this?

 

i go to take the cluster out and all of the sudden as im turning the screw on the right the display lights up, i might of over tightened that screw when icleaned my headlight switch, cause i remember making them really tight in order to prevent sqeaks or rattling. THANK YOU GOD!
