Hey all, so i've had my phat DS since the day DS came out in NA so pretty much five years now. It's held up really well until a freak accident occurred recently and a large textbook dropped on the touch screen. Now the center of the touch screen is erratic and the screen reads the stylus millimeters to the side. The rest of the touch screen is fine. I've considered sending the DS to Nintendo but I would like to know the price of repair first. Also, my serial number has long since been scratched off and my box disposed. So what are my options? Is there a way I could replace the screen myself? Thanks a lot.
