I have a 2011 Dodge Journey RT with the same problem. With a bit of cussing I found the problem. The fix requires electronics skills and specialized tools (solder station, microscope, and good soldering skills)
While I had an assistant in the driver seat with the car in reverse, wiggled the cable at the connector and at the camera with no video appearing. I tapped the lens housing and you could clearly see the video flash on / off, Indicating a break in the circuit somewhere.
I removed the camera, cut away the heat shrink, soaked the plastic seal with alcohol, and carefully used a razor blade to separate the housing to expose the circuit board.
The camera circuit board solder joints are flowed with lead free solder. Anyone you plays with electronics will hate lead free solder!
During inspection I found the following issues:
1. Cold Solder joints
2. Filter choke was separated from it's connecting pads from slamming the hatch too hard.
3. Header cable female pins had a loose connection
The fix:
Nothing on the circuit board is labeled. After a bit of research I found a replacement part from Digikey.495-4598-1-ND
B82787C0104H002CMC 100UH 150MA 2LN SMD AEC-Q200
1. I removed the old choke and solder in the new one. Glued with with UV cure glue to provide more support.
2. On the top side of the circuit board the inductor had a cold solder joint. Removed the inductor Re-flowed the part.
3. Directly soldered all cable wires to the mail header pins.
Re-assembled and glued/sealed the unit with UV cure glue (any plastic glue will work though).
Here are some pics... Sorry i didnt take a pic of the wires soldered to the heard pins...

Do you know which wires are which? im trying to convert the original harness to RCA to add to my journey that didnt originally have camera. I think red and black are fairly obvious. Do you know what the other 3 are? video +, video -, and maybe reverse? Thanks in advance for the nice write up! hopefully i wont need it.

Intermittent backup camera
Thanks Sparky for the detailed description of the fix, but I'm afraid that's a bit beyond my skill set. Do you perchance know the Mopar part # for a replacement camera? Replacement would seem to be the easier choice for me. I've looked at a variety of websites but can't find a part #.
