I have a composite cable (one white plug and one red plug for audio, one yellow plug for video) and the TV I'm currently using has the following connections: left audio, right audio, Pr (red socket), Pb (blue socket) and Y (green socket). I know that the red and white audio plugs connect to the left and right audio but I don't know what to connect the yellow video plug to (it may not be possible, I don't know). Can I connect the yellow video plug to the green 'Y' socket? Sorry if this is a bit of a silly question. The manual that came with the TV was basic, to say the least.
