https://youtu.be/1cy9LGTzkuE Describes my issue. Blank screen, no cracks, all internal connectors secured. iTunes recognizes it, is able to to update it, but nothing shows up on screen. Screen remains off. Screen and Digitizer only broke, or logic board broke?
Most likely screen and digitizer broke if the phone has never been serviced before. The flex cable up to the very end of the display assembly seems to cut for some unknown reason (What I mean that this is a common issue and has happened to quite a few people). If the phone has no water damage then I am pretty sure you will need to replace the whole front display assembly (Screen + Digitizer).
