You can't go from HDMI to component via a cable. It won't work - period. The digital signal of the HDMI has to be converted to the proper analog signal of the component.

There are a ton of these (what I call) scammer cables out there. I've been told that there were a couple of devices put out early on whose HDMI ports would put out analog signals, although, I've never seen one, read about one, nor has anyone ever been able to provide me with any specific device that did this.

You can use something like this - link - or you can provide the make and model of your TV and we can perhaps make some other recommendations.

If you have a DVI (guessing you don't) on the TV or VGA, you'll more than likely be better off going with one of those - and much cheaper.
