I have a Total vision camera on my coach that is giving me trouble. It starts flickering and getting darker and eventually will go out. Then it will come back on and work fine for a few miles and then do it again. I had this same problem last year and Newell replaced the camera. Worked fine until last week. The weird thing is when it starts flickering you can't turn the camera off or adjust the angle. Any help would be appreciated. Thanks, Mike
