There are a few things that need to present or applicable for this to work.
First off you need to have either a HDMI cable that can be plugged into your TV( tv and laptop must have one for this option to work). And you'd need to have the channel on your TV set to which ever channel recieves HDMI input.
Second you could have a monotor cable with two ends to attach to your laptop and TV as well as an audio cable like you get for computer speakers to have a line in and a line out, you may need an adapter for the video, usually with newer tvs like my 25.5" LCD HDTV from Samsung they provided this cable and a adapter. After they are connected you'd still have to set the channel to the correct one for the input to receive a picture from your laptop for example my tv channel for my PC is called DVI and my HDMI connection is HDMI 1
If you dont have either of those then you would need an S video cord and a audio cord with it to connect your output (from laptop) to the input hole (into tv) for this to work. And the channel would have to correctly set again.
If none of these help please post in more detail.
