I dont know what I am doing wrong...I have the pioneer plasma PDP427xd and am trying to connect it to the xbox 360...with no success....I am obviously missing something really basic.... I have used the HD AV cable to connect the red, green and blue coloured connectors to the back of the tv into connections marked component video: Y, PB, Pr, this is Input 2. But even when I select inout 2 on the tv there is no picture. Please help! I can only hear sound if I connect the audio cables to the side of the screen but thats input 5.... Please help!
