VGA to Component video cables only work if your VGA device is capable of outputting an RGB Component compatible signal. Unfortunately, computers can almost NEVER do this.
What you are going to need is an actual VGA to component converter. This type of converter will take the VGA signal from your computer as input and convert it to a true RGB Component signal to go to your TV. The cable cannot accomplish this, and just changes the physical plugs. There is nothing in that cable you have to convert the signal from one format to another. VGA is a 5 part video signal while the Component is a 3 part signal. The horizontal and vertical sync signals need to be combined with the green video channel so that it can be sent as a component video format.
I have personally used more than a dozen of these converters and the one that seems to be the best compromise between quality and price is the one found at vgatocomponent.com. You can see their page at this link:

I would strongly recommend returning that cable for a refund if at all possible. Those cables only work under very specific circumstances, and are generally intended to be used to connect an RGB component source to a VGA projector that supports RGB component signals through the VGA port.
Connect both devices.
Set the tv to the S-Video display port.
On the laptop, right click on the desktop, click properties
click on the Settings tab on the top right of the Display Settings option box.
Click on the 2nd monitor and click extend to this monitor option at the bottom of the box.
Click Apply
If that doesn’t work, look for the F Function Key (Usually over the F5 or F7 keys) that shows 2 monitors side by side. Try that combination and you should have better luck.
