RCA to VGA won't work?

Is it just a cable, with no circuitry? Is your tv an old style CRT tv? a cable isn't enough in that case, since VGA runs a non-interlaced signal at a different frequency compared with a normal TV signal. If you have an LCD screen, it may be possible to run the signal through a DVI if your TV has such a socket, and if it can accept analogue signals. It all depends on your TV. edit: It could be a HD connection - you can see the various connection here, with explanation. What is the model of your TV? The S-video cable suggests that this is a std. composite connection, and a composite input on a TV will not accept the RGB signal from a std. VGA source.
