Depends which connectors you have on both. TV could have DVI, HDMI, S-Video, Component Video... Laptop could have DVI, HDMI S-Video, VGA... Once you know what ports are available, go to an electronics store ask for help finding a cable and/or dongles that allow your laptop's ports to connect to your TV's ports. Personally, my Macbook Pro and MB Air have mini DVI out and my TV has HDMI, VGA, Component Video and S-Video in, so I use a mini-DVI to DVI cable with an HDMI dongle on the TV side. YMMV.
