Water damage and possible diagnosis!
My son dropped his 3ds in the sink he said only half of it became submerged but then tried to plug it in and this caused it to stop completely-dead!. It's now about 3 months and given its time spent in rice extracting all the moisture it could and a new battery it turns on but the top and bottom screens and the round joystick are completely unresponsive, although some of the other buttons work e.g start button power! What I want to know is does anyone have a possible answer to my problem as I will try and fix it myself if I know the part I need?? Any advice would be great.
