Back up camera Not working

2007 Tundra Limited Black, In-dash Nav JBL edition. I bought this with 205,000 miles on it, near perfect condition. I am having an issue with the backup camera. It was working off and on then stopped altogether.
I cleaned the connections with electrical cleaner and added Dielectric grease. started working better, then it stopped again. So out of frustration, I Cut the OEM connectors off and Hard wired them together with Heat shrink butt connectors at both factory connector spots(under back bumper and inside tailgate)
This actually worked, for a while. One day I lower my tailgate and no more camera.
I redid all connections and soldered the connections together, covered with Heat shrink, and still no picture.
I'm now thinking my Camera is bad. What's the chances?

 

Make sure the backup lights are coming on. If they don't get power, neither does the backup camera. The switch on the transmission could either be bad, or out of adjustment.

 

Yes they work. also, the Screen comes on and shows a black image, but no camera image.

 

Get one of the license plate mount cameras (they're pretty cheap) and wire it in to the existing wiring. If it works, the camera's bad. If not, it's somewhere in the wiring.

 

I have a license plate one. Any clue on how to wire to the factory harness? It's a 12v and oem is 6v. So I know my power needs to be on a different power source. Not sure what to do on the video connections.

 

The video should connect the same way. The power on the OEM unit must be coming in through the radio. You can wire the license plate unit straight to the backup light power.

 

Solution. I had two issues. I hooked up 2, 4"Led pods and tapped into the reverse lights. This i believe caused interference with the camera.

I had a license plate style camera, so I hooked up to the reverse lights and then tapped into the negative and positive camera wires. Blue - and Red +. This works perfectly

 

Can you supply a link to the license plate camera you used? I have the same issue since hooking up two LED reverse lights in my custom bumper. Camera screen comes on blue in the mirror and then blacks out. Been trying to figure out why.

I believe that the LED add-on is the source of the problem.
I've seen in other threads that this can be a major issue, but I really wanted those lights back there. Mostly because the old camera for 07 didn't have a night vision mode like the one I installed.
When I get some free time I'm going to make a Wiring Harness to run up to the cab and hook into a toggle switch for the rear lights.

 

I purchased the license plate camera. So you tapped the red/black of the camera into the Blue/red of the original tailgate camera harness? What about the yellow cable with the short red wire?
