DS Voyager side camera fail

[JCCampbell]

The passenger side camera on our '22 DS 4369 has stopped working. When activated by the turn signal, the screen reverts to a white out with a pair of green-yellow-red-colored lines as if showing distance. Other screens seem to be working fine.
Has anyone encountered this? MH is nearly new. Could it be something simple like a loose cable? Any thoughts on trouble shooting?
MH is still under warranty but trip to dealer is multiple hours, especially since they generally need to keep it for parts or repairs.
Thanks

Under your dash you should have a small module with three camera input connections, a video out to the monitor and a few wires to the turn signals, power, etc. A common problem is for one of those connectors to work loose from vibration.

Thanks. Under the weather and unable to check yet, but that's a good start.
