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 [https://www.youtube.com/watch?v=Pq1Ad3EObac|video] and also the ifixit [[Topic: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.
