Hi, I sold my Xbox 360 to a guy who is claiming that his system doesn't broadcast to his HDTV correctly. He wants his money back because it's broadcasting in black and white. Has anyone ever experienced this problem? Is it a problem that is caused by a bad system, or does he have bad settings on his tv or a bad cord, or something? I don't have an HDTV so I wouldn't even have known if there was a problem with the system. It broadcast in color just fine on a regular tv.
