Welcome to the forum.
Seems like you're in the movie Tenent. LMAO.
First try to do a system restart. How to do that is holding a combination of the button on the command controls, it may make it work again.
You can google how to perform a MZDconnect restart.
Mazda Dealer will sort it out, most likely a loose connection, that usualy the case with LCD screen on computers.
Let us know how it goes.
