Question about my Xbox plugged into my TV through HDMI cable

HDMI handshake, look it up on google.

I'm not sure about your set, but on mine it requires a different source channel. Like, when you probably switch over to either A/V or Component channels to display your games, perhaps your TV has an HDMI output channel that you need to switch to? My TV has them for TV/Air, AV, component, HDMI, VGA. Once I got HDMI for PS3, I couldn't use the component channel anymore and had to switch over to HDMI. Hope this helps.ErikWaters

That's what I was talking about. I have different channels for my cables. I have an AV channel, 2 Component Channels for both sets of component ports, and 2 HDMI channels for each HDMI port in the back of the TV. When I plug my HDMI cable into the TV, turn on my 360, and then go to the HDMI channel it says "receiving signal" then says "signal not found".
