Aircraft
While descending via a STAR at our destination the Master caution light illuminated along with the EICAS message TE FLAP ASYM and the TRAILING EDGE warning light on the forward panel. The flap handle was up and the flap gauge indicated flaps up as well. There were no roll tendencies. Due to the asymmetry warning the trailing edge flaps were locked out. We completed the emergency checklist which directed a VREF 30 + 40 approach and landing. We then declared an emergency and flew an ILS approach to an uneventful landing. After landing emergency vehicles scanned brakes with infrared and determined no hot or smoking brakes. Brake temperature in aircraft never rose above Level 2 temperature. Terminated emergency and taxied to gate. Maintenance found a left-hand wing position XMTR connector loose.Earlier in the flight the autothrottles failed as well; but this was a minor inconvenience during the emergency.
A B757-200 flight crew declared an emergency and landed with no trailing edge flap extension after receiving TE FLAP ASYM EICAS warning during their descent.
