VGA card to TV & S-VIDEO & RCA OUT cable? - tv out video card

I bought a VGA cable television similar to here: http://www.prlog.org/10161594-vga-card-to-tv-video-rca-out-cable-adapter-free-shipping. html
But if I can not connect to my laptop and the TV screen on my TV is black, what can I do?

I have a Compaq Presario CQ50 on Windows Vista
I also have a Mobile Intel (R) 4 Series Express Chipset Family graphics card. Can anyone halp me?
