Rear camera inoperative in 2015 Itasca Sunstar 35F

[Upinsmoke]

Morning, I just switched out all 3 of my batteries for new ones, and when the new ones were installed, the rear facing camera no longer works. The radio portion still works, but the camera icon indicates "off" and pushing it does nothing.

I've included a pic which may, or may not be of any value.

Any thoughts appreciated.
