Did you mean component?
Typically an A/V cable is a Composite video signal (yellow plug), and two analog audio signals (red and white plugs). So if you plug an A/V cable and your TV says Composite, then it's correct.
Maybe you meant Component? This is three video signals (red, green, blue plugs). Of course usually you also have two analog audio signals (red and white plugs) as a separate cable.
To save space and volume, several Samsung TVs have the same connector for Composite and Component, where you can plug the yellow Composite plug into the green/yellow plug of the Samsung adapter. Other TVs have separate yellow and green connectors.
So I'm having a problem. My 360 is hooked up via AV cables but my <span id="INSERTION_MARKER"> LN22<span id="INSERTION_MARKER">B350F2D 22 in LCD TV thinks its hooked up composite. I tried resetting my 360, still showing composite. I tried everything I can think of with nothing getting fixed.
