Sony, Japan has announced a free repair program for the Sony PSP. This repair is to correct a defect where controller buttons on some Playstation Portable (PSP) units may become stuck and not return to their default position. The defect occurs in part of the initial shipment of PSP units and is caused by excess plastic not being completely removed during the molding and manufacturing process of the outer cabinet. As a result, when a button is pressed, it can become caught on the excess plastic and not return fully to its default position.
