First, welcome to TSF.
Relax, you're almost there. You have the audio hooked up correctly. Now you need to do two things for video: hook up the S-video cable to the "Video in" that corresponds to the audio. Most of the time they're grouped or stacked together to make it clear which goes with which.
Now for the critical part. You have to set the computer to a resolution that your TV can accept. Try 800x600.
Once you do that make sure the TV is set to play the input that corresponds to where you hooked up the audio and video plugs and off you go.
If you're still having problems post back with the make and model of the TV and we'll try to help get it working properly.
