I connected a v2 Pi NOIR camera to a Pi Zero W and the jpg image it records only contains grey vertical lines, rather like an untuned analog TV set. I have tried viewing the image at different sizes and orientation, but there is no discernible image that I can see - it is definitely generating a jpg of something, though. There are no obvious error messages when I use the ‘-v’ option. I updated to Raspbian 9 (stretch) last week and I did initially install the ribbon cable upside down. Is the camera damaged or is this something I am doing/not doing? Any guidance welcome at this point.
