I just got a 42 inch hdtv hitachi plasma tv yesterday. I was wondering how to play video games on it. The white, yellow, and red cords go into the side of the Plasma, and the other into the outlet. But what screen to do i go to make the game screen come on the plasma, like in other tv's there was a tv/video button to push and that did it. Channel 2 and 3 dont work. Any Suggestions? Do i need a special cable or something?
