If you see the low battery symbol that proves the screen itself is working and the problem is with something else. Either you have a bad battery that doesn’t take charge, or current doesn’t get to the battery to recharge it. Trying a known good battery would be a first step. If that doesn’t change the picture it might be a bad charging dock or a faulty charging circuit. Double check all relevant connectors too, with some magnification and good light.
