I have an old 17WLT568 TV/DVD Combi. We use it to watch Sky using a "magic eye". I was trynng to find out why the clock light comes on in the middle of the night and found myself on Freeview when I was trying to re-locate the Sky input. Now when I press Menu all I get is the Freeview one, not the basic TV one with the source option. How can I find this again?
