Guys, I'm hoping one of you may be able to assist. I've just had Sky+ installed and have it connected via a JS Tech box to the VGA port on my PW7. The problem is I'm getting no picture at all. I've confirmed the Sky+ box to be working correctly by plugging it into the SCART connection on my old TV and the PW7 displays fine when connected to the VGA port on my laptop. Any ideas?
