Major Component cable issues.

So recently I got my cousin some Component cables to play his ps3 on HD. He doesn't have a fancy LCD or plasma, but it's a wide screen and quite old. But it goes upt to 1080i. We installed the component cables, no problem at all. We played some hardware games, no problem. But when we played Battlefield 1943 and Burnout Paradise, it wouldn't show up, it was black and fuzzy everywhere to the point of which you can't even see anything. Fat Princess worked fine though. I am seriously confused. Help anyone? Thanks.

Your television might not support 720p. Go into the system and video menu and uncheck the 720p check mark and give it a shot. My friend has a HDTV that supports 1080i and 480p and he was having the same issues.
