Otherwise touch failure that's not due to a bad screen can be due to a number of things on your logic board: the connector, some caps or filters leading to the touch ICs, or the touch ICs themselves.
This is repairable but not a DYI project nor for a tech not trained at Microsoldering.
Most probably touch IC failure.
It (they) will need replacing or reballing.
