My iPad fell off the dining table while it was charging, and hit the floor on the bottom right corner. There is a small dent there, nothing more, as the table top is only about a metre and a half off the ground. But now, the color on the screen has changed to a grainy, pink, blue and white one and nothing I've done is working to fix it- I tried restarting it a bunch of times, I pressed the home and lock buttons simultaneously, and even hit the Apple logo on the back a couple of times. I'm worried now cause it's out of the 1 Year Warranty period, too. What can I do?
