There are many reasons that could cause the screen in a 2015 Nissan Altima to not work. The circuit board could have a malfunction like a blown resistor or a bad chip. There could be an electrical connection that has become disconnected. The LCD screen may be bad or has an electrical short. There has been reported instances of a progRamming issue causing the display to stop working, an update fixed it. It is possible that there is a blown fuse, check the passenger compartment fuse box to verify that the radio fuse is good or not. The ECU may have a malfunction and cutting power to the screen. I would advise takeng Your car to the dealer to have them investigate the issue.
