2017 Chevrolet Silverado 1500 - Radio trouble

my screen keeps blanking on and off causeing my radio not to work on my 2017 silverado

Are the power wire and ground wire to the radio OK? Is the fuse secure in its place? Are all connectors secure? It might help to unplug connectors and plug them back in.

Is this the radio from GM or an aftermarket radio?

I believe there is a software update for this problem. check with the dealer. if the radio does not work and has a blank screen there is a temp fix. pull the radio fuse with ignition off and then put the fuse back in.
