So my car stereo fails to display any type of video input. Will only get audio from dvd movies with no picture (black screen), similarly for my rca inputs, when i connected my game console, i get audio but no video. Everything else works fine however when i slap in a dvd, i get a black screen with only audio. Can anyone assist me to rectify this problem? My deck is a kenwood dnn992, if anyone can recommend someone to check it out, that will be helpful as well. Btw i attempted to rectify the issue by doing a factory reset but it didnt work.
