blank display

I have a 2012 Navigator and this morning I have a white screen on my display with no navigation, no stereo, no back up camera display and no Synch. All of those functions associated with the touch display screen are non-operative. Has anyone else seen this and is there a fix that I could try...

Hello, does anyone know why have no display, radio will run, heat would blow , we did reset battery, that lasted 2 days and back to a blank display . ty for any advice.
