MFD Touch Functions Have Failed.

2007 Prius. 215k miles. New 12v battery 2 weeks ago. New traction battery today. None of that affected the screen problem but I thought they should be noted.

Screen displays normal information, including backup cam, nav, and all energy, limate, and radio displays.

Unfortunately, it is almost always unresponsive to touching the "buttons" on the display. Once in a while, it will respond, for a time or two but then becomes unresponsive again.

Is there anything I can try to revive it?
