If there's the options in the NV control panel make sure your output format is Pal_I if its outputting at 480p, also try outputting at 50Hz (incase the screen doesnt support 60Hz, a lot of older screens can't do 60hz and go black and white/blank when switched to the input switches to 60) and as above check the jumpers
