I have wired up an old 5.5" playstion lcd screen to my computers PSU its all working when I plug it into a playstion. I want to wire it up to the TV out on my graphics card. There is a phono connector with the screen but when I plug it up nothing on screen. I have connected it DVD camcorder PC etc nothing, but connected to playstaion fine. So how would u connect a phono or SVID to multi av in.
