2021 DVD Random Start

[wbeal]

2021. OEM Rear seat entertainment system. After driving 30 to 45 minutes with the system either off or on(sometimes but not always) both screens will flash on and display only snow with all of the red icons flashing at the bottom of the screens. None of the buttons nor the remotes will work to shut down the screens. Occasionally, while the screen is in "snow" mode, the screens will flash brightly almost like a flash bulb. That's a real joy for passengers in the back at night. Can not replicate at the dealer. Would appreciate any thoughts.
