## Discrepancy

AT FLIGHT LEVEL 370 GOT AN ECAM DUE TO HIGH CABIN PRESSURE, SHORTLY AFTER THAT THE NR 2 PRESSURE REGULATOR FAULTED, DONED OXYGEN MASKS STARTED A DECENT AND RAN THE ECAM. ALL PRESSURE REGULATING VALVES SHOWED CLOSED ON ECAM. THE CABIN PRESSURE  CONTINUED TO CLIMB UNTIL IT MATCHED THE AIRPLANE  ALTITUDE.  COULD NOT GET THE PRESSURIZATION TO RECOVER.  T/S PER TSM 36-11-00. NO CURRENT FAULTS OR LOGGED FAULT ON PNEU CONT 1 OR 2. SUSPECT PNEU CONT 2.  R & R NR 2 PNEU CONT PER  ABOVE REF. OPS CK GOOD.
