S-Video Cable wont work

I ran through the same problem. Exactly WHAT are you trying to watch on your TV? What operating system are you using? You cannot run two monitors at once, if you're using Windows XP, and will have to get into your display sub-panel. I'll try to walk you through it.

there is a setting on your laptop somewhere that will allow you to turn on the "TV-OUT" function. try right-clicking over your blamk desktop, choosing 'Display Settings' and poking around there, maybe under 'Advanced.'

you'll find it eventually, but the picture might not be what you're hoping for. S-Video doesn't compare to a computer monitor.

This may not be the case at all, but, I'll throw it out there; IMHO S video cables are poorly designed pieces of dog do do. If one is not very carefull inserting the cable(s) into the appropriate jacks the little pins tend bend and break.
