Problems with rear view monitor

[Lonestar50]

Class A has two monitors/screens. First one continuously shows rear view. Second shows other media, (radio etc.) but switches to rear view when in reverse. The first monitor just stopped showing the rear view picture and now only shows a DVD screen. Second monitor is still working fine, and shows rear view when in reverse, so the problem is not with the camera. Did I inadvertently change a setting? Could it be a wiring issue? Need help.

Also look for a loose connection. I dismantled my camera installation when it stopped working, only to find that one of the connections had come loose in the back of the monitor. Spent a couple hours trying to fix something that required 30 seconds! I learned to look for the simplest explanation first before "going to the dark place," as DW would say.

It sounds like you changed a setting to DVD.
