Hi, new here, sorry if this has been discussed but I couldn’t find it. I recent got a 2017 GMC Yukon Denali. It has the headrest dvd systems installed factory/deal (invision). Passenger side works fine, the driver side powers on and you can see the screen selection (channel a, b, av, etc) but can’t see the dvd playing but you can here it on the headphones. Also can’t see the gm welcome screen like on the working one. I have read it could be the control box but I’m not sure where to find that. Any advice on where find the box or what else to try before I dig into it? Appreciate it.
Headrest dvd system one screen not working properly.

Plug something into the Aux jacks in back. I assume there are some in back, my truck is a Gen behind yours. See if the system has been changed to override that screen with a different input.
There are aux jacks on the headrest itself is that what you mean? I can select source, channel a, b, aux, and usb. But the screen doesn’t show any video.

My thinking is that if you jack in on one of the other inputs and you get video, you’ll known immediately it’s a settings issue, not a failed part.
