B767 HAD HOT BURNING ODOR IN THE CABIN. CAUSE WAS FOUND TO BE OVERHEATED VIDEO PROJECTOR.

Narrative

OVERHEATED VIDEO PROJECTOR. DURING TAXI OUT FOR TKOF; THE #1 FLT ATTENDANT PURSER NOTIFIED US THAT SHE NOTICED A BURNING ODOR IN THE FIRST CLASS CABIN NEAR THE CEILING. THE RELIEF FO WENT BACK TO INVESTIGATE AND CONFIRMED THE PRESENCE OF AN ODOR. WE ADVISED GND CTL AND OPS THAT WE WOULD NEED TO RETURN TO THE GATE FOR MAINT TO INVESTIGATE THE CAUSE OF THE ODOR. AFTER RETURNING TO THE GATE; MAINT DISCOVERED THAT THE OVERHEAD VIDEO PROJECTOR IN FIRST CLASS WAS QUITE WARM AND HAD APPARENTLY OVERHEATED DURING THE PLAYING OF THE PRE TKOF VIDEO. MAINT DISCONNECTED THE CANNON PLUGS AND SECURED THE VIDEO PROJECTOR PER THE MEL AND WE REDEPARTED WITHOUT FURTHER INCIDENT. FLT ATTENDANT IS TO BE COMMENDED FOR HER QUICK ASSESSMENT OF AN ABNORMAL SIT AND FOR NOTIFYING THE COCKPIT IMMEDIATELY. IT CERTAINLY WAS MUCH EASIER TAKING CARE OF THIS PROB ON THE GND THAN AFTER AIRBORNE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: PLT WAS FLYING A B767- 300 ACFT. THE CAPT HAS NOT HEARD OF A SIMILAR INCIDENT IN THE B767 OR ANY OTHER ACFT. THIS APPEARS TO BE AN ISOLATED CASE. THE CAPT WAS MOST APPRECIATIVE OF THE FLT ATTENDANT'S QUICK CATCH OF THIS PROB.
