More Information - Camera Issue

[LDRider]

All

I am asking again now that I have a little more information. After having the bus jumped by FMCA Roadside assistance my rear camera and right side camera on a Thor Tuscany 45 AT 2017 have stopped working. I get No Video Connection on the radio screen.

I have been told there is a video switch box behind the radio Model # CSW3T 3 Camera Stand Alone #0453209 that might have gone bad. It appears no to be a fuse as the left camera is working and there is only one fuse for all three camera.

It appears I have to remove the radio (picture below) to get to the switch box. Has anyone done it? Crawling behind there only seems to be two nuts holding it in but want to get some degree of confidence I am doing it right before I start. The dealer has said it might be the switch needs to be replaced or the connections have some lose.

Thanks in advance for any help.
