I've taken my PSP apart to fix the joystick. For some reason, it's stuck in the Down position. After putting it back together, it still doesn't work. I was wondering, have any of you had this problem before? If so, how did you fix it? I don't want to buy a new joystick because it's not my PSP. I'm just waiting to get a new one because mine was stolen. In the meantime I borrowed a friends and I really don't want to spend money on his PSP. Any ideas?
