Was the phone off when you did the exchange? If the phone was just asleep, it can sometimes need to be reset to work with a new LCD. Turn the phone off with the working LCD, then do the swap. If the phone was off and power cycling doesn't fixing the problem you may have bought a bunk Display. Where did you buy the Display? If it was from us, contact firstname.lastname@example.org to set up a return.
