If you read the fine print on those adapters, they'll tell you that you need a device that can specifically encode a component signal over VGA. You clearly do not have such a device. You can try as long as you want, it won't work.

To bottom line it, if your TV doesn't have a VGA input, then you'll need a special encoder device that can take the signal from your laptop and turn it into something your TV can understand. These aren't typically cheap either, so most people decide it's not worth it.
