HDMI is digital, while VGA, S-Video and RCA are analog connections.

You can use a VGA to RCA adapter or and S-Video to RCA adapter.

And take a look whether your TV has an S-Video input. You may only need an S-Video cable then. Be careful because S-Video cables can have 7 and 4 pins.

You may also need a separate Y audio cable if you want to ouput sound from your laptop on your TV.
