The Aladdin Jr display in our coach (07 Contessa) started has acting up. I’m unable to select video from the rear or side cameras. When attempting to select a video source on the display monitor or from the joystick it says no video source. The engine data displays are OK and the turn signal cameras display when the turn signals are selected. However the rear camera does not display when the transmission is in reverse. Any ideas on a possible cause? Connections to rear of display unit seem OK.
