I have a Sony 900 which I have been using to back up old videos to DVD and it has worked fine. I have just plugged a scart from my Sky+ box to the line 3 input of my Sony 900 and I get sound but not picture? Is there any reason for this? So I have the Sky box (set to RGB) connected by scart to line 3 in my Sony 900 (set to Video/RGB input) then component out to my Yamaha amp then component out to my Panny 6 plasma screen. I've tried searching but cant find a definitive answer. Any clues gratefully received.....!
