Help, I'm out of my depth. I've just received my screen from John Lewis. I expected a tuner and terminal board, (which I didn't need) and a RCA board which I thought that I did. However, the board that was included had a serial port which is absolutely no use to me whatsoever. John Lewis are saying that the Panasonic tuner is better anyway for quality and because you don't have to keep unplugging the different cables for the different equipment. Has anyone else been down this route with John Lewis or can offer any advice.
