S-Video to VGA Converter

Hello friends..
Sorry if this has been asked before but search turned up no results specific to my plight. Well, I recently purchased a Toshiba Satellite A500 laptop (Windows 7) from Best Buy through http://www.dealrocker.com discount deal. I tried to connect it to my TV, but all my efforts gave me no result. My laptop has VGA port and HDMI port, but my TV is pretty old and only has S-Video. I got a VGA to S-Video converter, but it gives me some tick tock noise and no video on TV. Any anyone help me to perform this task?

Thanks in advance..

Not really sure but I'll guess that your old TV isnt compatible with the digital signal and you need a transcoder
