Out of the blue a large black box shows up in the middle of the screen. It is a perfect rectangle and takes up about 80% of the screen. When you move the volume button or change a channel it goes away but comes right back
This is a background for text, even though you aren't seeing any text at the time. Since it covers most of the screen, it sounds more like a demo mode screen than closed captioning. Go into your setup menu and make sure that neither of those is selected. If necessary, restore the factory settings. I'm assuming that this is coming from the tv itself, and that you don't have a VCR, Tivo, etc. Good luck!

You have your TV in the "Teletext" mode. Go into the TV menu and select the closed-captioning menu and turn off the text function. What you are seeing is the result of the TV's captioning circuit latching onto a false text pilot signal and then throwing up the black box on the screen.
