■ got a sylvania tv trying to connect my red yellow and white cords to my DVD player to watch a movie the sound came in but not the picture what is I'm doing wrong

missing the video cord

If both the modulator and the DVD player include S-video connections, run an S-video cable between the two devices and plug an RCA cable into the red and white audio connections.
