My back up camera was glitchy for a while then went black. Sometimes it (the screen) would give an error message, sometimes it would go black, and sometimes it would not even act like the vehicle was in reverse. I put in a new camera, and it worked for about 20 seconds then went black again! Not sure what to do. I looked at the wire harness and the fuse. Don’t see anything obvious. Any help would be appreciated. Thanks
