Unit will not charge, even after battery replacement.
I tore down my A1475 and successfully replaced the battery this weekend. The original symptom was that the unit discharged rapidly, and would not take a charge (yes, I tried multiple chargers and cables, several OEM and non-OEM, and non would charge the unit. Never even recognized a cable).
The new battery had about 40% battery in it, and the unit powered up fine once I replaced it, but it STILL won't charge. So...what next? Should I spend the time trying to replace either the lightning port connector, or the battery plug (the small rectangle, connected to the logic board, that screws in to the battery)? Both require soldering, which is not my favorite past time. Or is it most likely a problem with the logic board itself? If that's the case I'm not going to bother.
I appreciate the help anyone can provide...thanks!
