Ok, so my 3DS' dpad is stuck in the up positition. Mind you, not the physical button itself, but the mechanism is being pressed on it's own. I know that I could disassemble my 3DS, but I don't have those specific tools and I don't want to break my 3ds. It's on 4.5 FW, so sending it to Nintendo is out of the question. Should compressed air be enough to fix it?
