## Discrepancy

SHORTLY AFTER LEVELING OFF AT FL410 WE STARTED NOTICING WHAT WE THOUGHT WAS A STRONG ODOR. PAX ALSO NOTICED THE ODOR THROUGHOUT THE CABIN . A FEW MINUTES LATER THE FMS SCREEN WENT BLANK AND WAS VERY HOT TO TOUCH. ABOUT ONE MINUTE LATER WE NOTICED A FEW SMALL PUFFS OF SMOKE COME FROM THE TOP OF THE FMS.  REPLACED DEFECTIVE FMS WITH ANOTHER UNIT.  INSTALLATION IAW MM 34-61-03   RAN ACFT & SYSTEM'S FOR ONE HR WITH NO SMOKE ISSUES.
