A shuttle orbiter General Purpose Computer (GPC) at Input Output Port (IOP) No.2 was voted out of a set with other computers. The computers were exchanged and the computer connected at IOP No.2 also malfunctioned, indicating the problem was with the IOP. A pin solder joint was found to be fractured. The unit was repaired without investigating the cause of the joint failure. Rework procedures were revised to require an investigation of the cause of a failure before any attempt to repair the failed component.
