my joystick refused to move in the up+right direction, so i took my psp apart and cleaned it a lil, hoping that it would magically fix itself. now the problem is worst: its constantly moving in the up+right direction without me pressing anything. thinking that i misplaced the joystick or something, i took out the joystick for a test, and its STILL moving up+right. the direction pad works fine (it overrides the up+right) so thats not the issue. Does this mean that its not the joystick thats broken, but the psp mobo?
