No they are 2 different parts. On the lilliput the touch controller is built in to the main PCB. The touch panel connects to the controller. I mentioned both because without testing it there is no real way for me to know. I would say replace it. If it is new and drifting already there is no way to tell if it will get worse over time. I am sure the money you paid for the unit was more than kind of green so the monitor should do more than kind of work right.
