MANUAL TRIM WAS SELECTED, WHEREUPON THE TRIM SYSTEM WAS FOUND FROZEN.  THE AIRCRAFT RETURNED TO BOS LANDING WITHOUT INCIDENT.  BOS MAINTENANCE FOUND THE ELEVATOR TRIM SERVO ACTUATOR HAD SHORTED INTERNALLY CAUSING THE SYSTEM TO LOCK.  THE SYSTEM WAS DEFERRED PER THE MEL AND THE AIRCRAFT RETURNED TO SERVICE.
