Yes - bring it to Verizon. When an unexperienced person starts doing physical work on a phone (like taking it apart, which has to be done in this case), he usually damages things, causing more problems. When he tries to fix those problems, he usually breaks or damages more things. Eventually he takes it in for repair (the carrier will take a phone in for a non-warranty repair even if you're opened it), finds out that the repair will cost more than a new phone, still ows the carrier for the work they had to do to determine what the problem was, and he has to pay for the diagnosis before buying a new phone.
Paying them to fix the problem (which in this case could be a loose connector or a bad screen) would be a lot cheaper.
