Why is my touch screen is not responding?

It's likely that the screen is just dirty. Try cleaning it with a microfiber cloth (like the kind you would use on a pair of glasses). If that doesn't work, there may be crumbs or other messes stuck in the edges of the screen (this can be enough to throw off the screen's calibration). If you see any messes in the cracks around the screen, try gently removing them with a toothpick or a spudger. If that doesn't work, you may be dealing with a larger issue like a damaged screen or a loose connection. If you think this may be the case, take a look at the LeapPad Platinum's troubleshooting guide to help you diagnose your problem and find the right guides to replace any damaged parts.
