Hello. I bought a samsung plasma 720p HDTV, and I have a DVD (not blu ray, just DVD) player and I bought component cables since the tv has no composite input. Weirdly, I get absolutely nothing with the component cables, when I select the source it should feed from, it says no signal. Even more oddly, when I hook it up with a composite cable, it actually works, just with no color in the picture. Why isn't it receiving any signal from the component cables? They're brand new. Thanks in advance!
