I bought a S-VIDEO 7 PIN to 3 RCA Cable TV to plug my laptop to the tv. The picture comes up black and white and there is no sound. Could someone please help. Thanks
First, s-video is as the name says video. There is no audio.
Second, it is doubtful that your laptop is also sourcing composite video in addition to s-video out of the 7-pin s-video connector.

Thanks. I understand that it is just video but I thought that since it had the three colors to plug into the tv it would do audio as well. What cable would you suggest I buy then.
I think you are barking up the wrong tree. The fact that you see black and white should tell you that.
But if you insist on pursuing this , buy this http://www.svideo.com/pro724.html
