I have tried to plug in my ps2 the right way, the PS2 is on but the TV says 'no signal'. So I don't know if I got the Red White and Yellow cords in the wrong places or if I'm on the wrong channel for it. Please help (:

You mean to say you still have an old IBM P/2? The last time I saw any of those boxes was back in 1992.

Video is driven over the yellow cable, audio is carried via the white and red cables.

Next you have to make sure that your cables are connected to the correct port on the TV and that the TV is tuned to that port.
