Why does my iPhone 4s screen show black and blue lines?
My iPhone screen shows only black and blue vertical lines. The screen is not cracked, and still responds to my touch. I've already tried restoring it on iTunes, and I did a hard reset (holding the home and lock button until it turns off and back on).
What parts of the phone do I need to replace to get the display working again?
