I recently fixed a A1 14 5G but now if you put a sim in it shows that the Sim is available but there’s no service signal. Also 5G Wi-Fi takes long to discover and is weak. I know for a fact that there is some damage to the charging port board connector. (1 pin is missing because or water Ingres) but it’s still charges and still connect to the PC. Can this board be at fault for the no signal?

@shaun77206 it absolutely can be. If I remember right your antenna cable connects to it. Any water damage is the hardest to troubleshoot and to repair. You also did not tell us what you "recently fixed". A good history is always helpful for further troubleshooting.

Sorry . I fixed the display which got damaged from water.note-only the bottom water indicator turned red at the port and main board show sign of water and indicator is still white.
@shaun77206 replace the sub board (charging board) and double check the flex cable on it. Make sure it does not have any corrosion.
