Hi, I'm trying to input an S-video signal from my DVD player (Sony DAVS-880, no RGB) into my TV. The instruction manual states that the AV3 port will accept an S-Video signal. I purchased a S-video to Scart lead, plugged it in and the picture came out black and white. I know the player is outputting correctly because when I plugged it into the front S-video port (AV4) the picture was fine. Whats going on? Is the cable at fault or do I have to adjust my telly? Many thanks.
