## Discrepancy

DURING INITIAL CLIMBOUT, THE PILOT REPORTED SMOKE IN THE COCKPIT COMING FROM UNDER THE GLARESHIELD AND RETURNED FROM THE DEPARTED RUNWAY. UPON INSPECTION, FOUND THE DIMMER CONTROL CIRCUIT CARD HAD FAILED SENDING SMOKE INTO THE PFD AND OUT THE TOP PFD VENT. NO OTHER WIRE(S) WAS DAMAGED OR SHORTED.
