I'm using a Sony VAIO Computer. It has an NTSC out jack, or at least I think that's what it is. A yellow colored jack with a symbol of a circle bisected by an arrow pointing to the right. It also says in the specs that there's an NTSC out jack, and I don't see a better candidate.
Yet, when I plug stuff in here, nothing comes out. I'm using a single pin yellow video cable to 3 separate video, audio L, and audio R pins. I'm wondering if this might be an on-board configuration error, something I'm not setting properly in the video display options? Sony's tech. support site is horrible. Any suggestions?
