My backup camera works when it wants to. 
sometimes the is no reaction by the headunit when I shift to reverse, sometimes a black screen with the warning message, sometimes it an actual video like it’s supposed to be. 
 

the camera hard wired to the left reverse light,  ground and power. 
this has been going on for years. Thought it was the cameras fault, now I’m not sure.  Any help would be appreciated. Thanks in advance 

Have you checked all your connections ?

Yes several times with the exception of the video cable, all connections are soldered and sealed.
