New screen unresponsive on iPhone 4S
I recently replaced my cracked screen and the new screen was totally unresponsive to touch. So I took it back out and put the old screen back. Now the old screen is unresponsive. I've done this before several times with no problem. I made sure the delicate cables were undamaged as has been suggested by other answers to the same problem. What else can I try? Anyone have any ideas?
