More then likely this is the control module called the rear seat entertainment ECU but we need to make sure there is power and ground at the display screen.
I included the testing that needs to be followed. As you can see it is saying that you need to check power and then suspect the control units. I would suggest going to the display screen and checking for power and ground. Then I would move to the control unit and then the DVD player.
Just to make sure, do you get any display, flicker, or input display when using the system or is the screen black 100% of the time?
