I tried loosing some of the screws and re assembly it still same issue ??
It will more than likely be a parts problem. · Faulty charge port. · Faulty battery · Faulty top flex. Try booting with it disconnected. If it still will not boot it will be pry damage. You will need to check around the connectors under a microscope and see if any components have been nudged off there pads.
