I too work as a repairer for an online retailer, we are repairing lots of iPhone 7's. Sounds to me like the flex has been nicked near the connector plate, have you examined it under a microscope? These ribbons seem super fragile compared to other models. Another possibility could be that you mention you have genuine Apple LCD, these must be reconditioned screens (if not then please tell me who your supplier is) which may have been damaged by whoever removed them or re-glasses them. Other than that maybe some of the black foam that surrounds the connectors got trapped in the connector? Have you tried this screen on another phone?
