What was found
DURING GROUND HANDLING WITH APU AND ENGINES RUNNING, THE CREW NOTICED AN ELECTRICAL SMELL IN THE CABIN AND COCKPIT. MAINTENANCE DISCOVERED THE PILOTS ADVISORY DISPLAY PANEL TO BE THE SOURCE OF THE ODORS. THE DISPLAY PANEL WAS PLACED ON THE MEL LIST AND THE AIRCRAFT RELEASED FOR FURTHER FLIGHT. THE DISPLAY PANEL WAS SUBSEQUENTLY CHANGED AND OPS CHECKED GOOD. THE AIRCRAFT WAS THEN RELEASED FOR SERVICE.
