mfd touch not working

Hi All, My 2007 Prius MFD touch is not working. Lights up, functions as normal it seems. Controls on steering work fine. The 7 buttons all work fine. Lights up fine and shows backup camera and other screens no problem. The only issue is the touch function does not work. I replaced the digitizer from one on Amazon and still does not work. This is the 86110-47220 model and before I drop $400 for a new unit on ebay. Anything I might be missing that I need to check into. A simple fuse or something?

Thank you in advance.
