I just finished replacing my cracked screen. Purchased the screen/digitizer through iFixit. The device turns on. The Home Button also works, but nothing happens when I touch the screen, which means I can't "slide" anything. There are also double vertical lines across the entire screen. Followed step by step! What did I do? Nothing ripped during replacement. I'm so afraid to attempt to pry open new screen to look around. I don't want to bust my new one! Any tips/hints would be greatly appreciated! Can't seem to find anything in the answers section pertaining to this issue -- just a white screen, which I don't have.
