Iphone 6 plus cracked screen, screen plus digitizer replaced but accidentally miss installed the cables. screen turns black. Is there anything that I can do? other than buying another screen?
This is a belated answer so hopefully it can be of use to folks who search for and find this question. When inserting a connector in the wrong place, it is possible that the connector was damaged. You have to closely inspect the connector, preferably with magnification, to see if any pins were damaged or if the plastic casing of the connector was mangled up. Any damage to the (screen) connectors will require that you replace the screen. If the damage is on the logic board connectors, then those can be replaced via micro-soldering.
