Hi @lyn8649

Has the phone been dropped or gotten wet at all?

Here's an image of the No Touch troubleshooting procedure from the service manual that may help.

Here's a teardown video and also the ifixit Samsung Galaxy A53 5G guides as well.

Looking at the troubleshooting guide the best result would be a loose connection. If that is OK it could be a faulty charge port board, a faulty display module or a faulty systemboard.

Change flex cable wich connect motherboard and PCB(daughterboard) and try it. If its working then great,if its not then you will check for FPC of LCD screen and FPC on motherboard.
