## Discrepancy

FLT 1418 LAX-PHL- DIVERSION - EN ROUTE FROM LAX TO PHL, CREW REPORTED SMOKE IN THE CABIN AND COULD NOT DETERMINE THE SOURCE.  AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO PIT.  AFTER LANDING, THE CAPTAIN STATED THERE WAS A SULPHUR SMELL THAT BECAME MORE PRONOUNCED ON APPROACH INTO PIT.    MAINTENANCE REMOVED AND REPLACED THE LT RECIRCULATION FAN.  OPERATIONAL CHECK GOOD.
