I have a JVC HDTV, and I have a few problems with connecting my Xbox 360. My TV has Video-1, Video-2, and Video-3. Video-1 being for connections with component cables and Video-2 for normal R/Y/W cables. When I hook up my Xbox 360 to Video-1 with R/G/B for HD play, and R/W for the sound, it does not show up on the TV, I can't even hear anything. Yet when I hook up the normal R/Y/W to video-2, it does show up. I'm thinking it's a problem with the TV... any help please?
