After 2 screen replacements my iphone will still not work. I need to know what else could be the problem for this catastrophe.
mattaposey, this can be caused by a bad digitizer connector. As you can see the connector lacks metal ends and this is what makes it a weak connector. It is easily possible to damage the connector by mis-aligning the digitizer connector
like this. Check the ends of the connector. The plastic of the connector has been compressed into the connector, causing it to flare out and preventing from making proper contact.
It can possibly be damaged port located on logic board
