You must contact Sony and have them repair it. This is for two reasons: 1) Buying a replacement screen and putting it in yourself on a Mylo 2 is a lot of work, and if you don't know what you're doing, I guarantee you you'll break it. 2) If you so much as open up your Mylo 2, you will void your warranty (assuming it's still under warranty) and then it will cost a lot more to fix it, but more importantly, if you open it up, it gives them the right (according to the customer agreement) to refuse to repair it. Just have Sony do it, don't screw with it.
