Back up camera shows blue

Hey guys, my rear view back up display only shows blue. Trying to get an idea of what happened. Worked like a charm until a heavy rain a couple months back

Thanks

 

Welcome from Ca. Silly question,,,,,, Is it full of water? Not that that would be what you're seeing but that might have caused the failure.

 

Welcome from WI. My camera did the same thing a few times after driving in wet conditions. Try unplugging the camera harness (behind the bumper on the passenger side), clean and dry out both plugs, apply some dielectric grease and plug it back together. This is what I did and haven't had a problem since.
