Connect my laptop to a TV via S-Video port

First of all, thrilled to see a website dedicated to laptop repair!!! I have got a small problem here. My laptop Toshiba Satellite A50 has an S-Video output. I have connected it directly through the cable to the S-Video input of my TV. But I tried my level best; it’s not displaying any picture of my laptop. Please tell me what can be the possible problem? Do I need to do any additional settings or install any driver? I hope this is not a too trivial question.

You do not have to install any driver to use S-video port. Connect the S-Video cable to the back of your TV and turn it on. Using TV remote control switch it from TV mode to Video mode (TV/Video button, Input button, etc…). Turn on the laptop and wait until it boots to the desktop. Connect the S-Video cable to the port on your laptop. Now you have to use Fn+F5 keys to enable TV video output. Press Fn key and while it’s pressed press on F5 key until the TV output is selected. When you done with TV, set the video output back to LCD using the same Fn+F5 keys.
On some laptops you have to enable TV output in BIOS and connect S-Video cable to the laptop before you turn it on.
