I am trying to connect a magic eye to my T.V. to watch sky in the bedroom but the T.V. isn't producing sound, despite there being a good picture. Everything has been connected correctly as far as I can see. Online, people talk about ensuring your T.V. is set to "PAL I" but I can't seem to change or check this. Any advice on how to do this or indeed how you believe to solve the problem?? Thank you, Calum
