Sony backup camera system

I started getting the "blue screen of death" on my Sony backup monitor system a few years ago.  It is intermittant, and if I have the camera on while driving, seems like it is affected by road conditions.  A "bump" will make it go blue, another bump will bring it back.  If I just leave it on, it will eventually come back again.  It seems to be getting more prevalent over time.

I think it is an intermittant connection either in the wiring or the camera itself... the wiring failure could be loss of +12V or ground to the camera, or the video signal connection. The blue screen is indicating the monitor is not receiving a video signal. I don't think it is to do with the monitor, since it still displays the blue screen.  The question is WHERE?  The cable into both the monitor and camera is not connectorized, so I assume there is a connector above the monitor, behind the TV, and another connector inside the top-rear of the RV, behind the bathroom cabinet.  Or the issue could be inside the camera itself, which seems most likely since it is out in the elements. 

I tapped on the camera and jiggled cables, while my wife watched the monitor, and could not duplicate the problem that way.

Has anyone out there encountered this?

I did not encounter your specific issues with my camera when it died a few years ago.   I did call the factory with ideas for repair.  They told me technology had moved on and there
were no replacements.  They also said most people have gone with the wireless units and have been satisfied.    I decided to go with a Tadi Brothers wireless camera that has a
monitor attatched to the rear view mirror in the cab. The camera goes right where the old one had been.   Way better,  sharp, image.    Wish I had done it sooner.

Thank you Jimmer for the input.  I'll look into the Tadi Brothers setup.
Did you just splice into the existing Sony cable (at camera and monitor) to pick up the +12V and grounds?

For 12 volt for the camera, I spliced into the marker light wire right by the camera.  So, Yes, the lights have to be on now when I use the camera.
For the monitor,  I used the existing 12 volt wire to the old one.   Had enough wire to run it behind the headliner terminus where it meets the windshield.
That wire is energized whenever the ignition is on.
