How do I know if my logic board needs to be replaced?
As Aiden suggests, more details would help us give you a better answer. That said, the problem is on the logic board when you can properly eliminate every other variable. Logic board repairs are not trivial and they are the last thing you want to undertake. If you are having “screen” issues, then try a known-good screen. If you are having camera or sensor issues, then try known-good cameras and sensors.
