Connector is on the logic board itself, nothing you can replace yourself there. It’s a through hole connector, pretty solid and I doubt anything got disconnected unless it got seriously bumped with the adapter in place. It might just be dirt, you may try cleaning it with fine tweezers and some alcohol dampened small soft cloth. You may as well try with some canned air. If nothing helps it might yet be some smaller filter or resistor gone bad but that would need some skills and tools to be fixed.
