Aircraft X went NORDO on the downwind. There was no reason given as to why the aircraft went silent. They entered into a 3;500 foot MVA (Minimum Vectoring Altitude). I tried to reach the aircraft on emergency frequency and back up radios.
TRACON Controller reported an aircraft on downwind lost radio contact and flew below the Minimum Vectoring Altitude.
