My 19" screen is dead. The car can drive, can charge. Responds to rebooting instrument screen, does not respond at all to rebooting the 19" screen. Brakes or no brakes. I have TeslaFi and it can still see the car and interact with it. Does anyone have any ideas or am I looking at financing a 19" screen replacement? Have not tried powering off the car and back on again. Will do that and report back.
