It could probably be the video cord for the SNES. It's the yellow one, I have an SNES and I have to make sure it's positioned correctly or there's no video. Try making sure the yellow cord is plugged up to your tv and if it still doesn't show anything, wiggle it around while still connected to the tv. If worse comes to worse, you can buy more video/audio cords.
