"D-Pad Stuck in Down Position"에 답변when this happens, there is a build up under the silver button itself. You need to disasemble it down to the mother board, and then (extremly carefully) pry up the plastic covering. This covering is attatched to, though seperate from, the White backing/mask. If you carefully pry this up, you will see a black build up between the silver button, and the gold contacts on the Mainboard. Remove this through a mixture of rubbing alchol, and force, and reassemble.
