Hi, I just bought this Sammy for my parents and upon switching it on I got the Auto setup screen which I canceled out of as I didn't have it connected to an aerial at the time. Now I have it connected to an aerial I have a problem. The setup screen doesn't appear, I checked the manual and according to that you can access this by choosing Plug & Play from the config screen in the menu. The problem is it is greyed out and not selectable. We are getting a No Signal message on the screen when selecting DTV. To me this would indicate a problem with the aerial but the old analogue TV works fine connected with the same lead. An suggestions? Is there a way to reset the TV so we get the auto setup screen?
