rear camera

Challenger 2014- the rear camera stopped working going down the road.
Display indicates no camera input.
I checked the connections behind the radio and the camera connections
are connected. The side cameras work.
I also checked the connection at the camera itself and it appears ok.
Where is the power source for the cameras? I'm going to look for a fuse today, perhaps a fuse let loose for a reason.
I have yet to switch camera inputs to see if the rear camera is actually not working.
Any help on power source or possible repair would be great.
Thanks

I have had it happen 2 or 3 times now. First time I found that the cable connection near the back of teh dash radio was caught down in the engine compartment pinched in the doghouse. No appearent damage, moving the wire fixed it.
Happened again, and I found that if I disconnect the wire (bnc type connector) near the back of the radio and plug it back in it worked.
I have yet to trace out exactly what the real problem o fix is.
I'm not positive, but I think the camera is powered through the signal wire by the radio unit in mine

I tried to disconnect the wire labeled Cam 1 and could not figure how to disconnect it.
It looks like there is a release button on the side but I was afraid to force it . I'm not fam. with a bnc type connector.
thanks for the reply.
I did go back inside and with 2 hands I did get the connector disconnected.
Plugged it in and still no signal.
My next step is to disconnect the camera itself and reconnect to see what happens.
If that doesn't then I'll go back to my original thought and switch leads with one of the side cameras if the pins are the same .

The power source for the camera varies. Some camera harnesses have provision for a power connection while others are directly powered by the receiver and/or monitor. So there is no one method of connecting them.

This is what was in my line. There is a short cable form the back of my radio, with one of these connectors maybe 6 inches away form the radio.

BNC connector - Wikipedia, the free encyclopedia

I gave up before I do any damage to the system. I contacted Thor and let the experts take care of it.
Thanks for the input.
