## Discrepancy

IAH FLIGHT 3122, DURING CLIMB THE CREW REPORTED THAT THE MANUAL AND AUTO PRESSURIZATION WERE INOPERATIVE.  THE AIRCRAFT RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE DIGITAL PRESSURIZATION CONTROLLER, OPERATIONALLY TESTED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
