Black box blocks out most of the picture. It will disappear when a button on the remote is pushed, and then reappear a few seconds later. The Magnavox model #HD 1905 C121, and serial #45236211 appear on the television.

It sounds like the closed captioning background.

Press Menu on the remote
Press Up or Down, Ch + or C- to get to Closed Caption
Press right side button or Vol+ and Mode will be highlighted
Press right button or Vol+ until it says Off on the right hand side of the Menu
Press exit and that should do it.

Hope this helps.

Black box in the middle of the screen

The closed caption is turned on. I don't have the schematic in front of me, so, I will wing it. There may be a button on the remote that says CC, if so then use that button to turn it off, if not then go to the service menu and you may have to search a bit. Either way it's an easy fix and you can do it yourself. If you can't find it, then, reply and I will give better instructions when I get into my shop next week.

Black box on screen

On your remote should be a button called TV caption or text. Turn off the closed caption as someone hit it and turned it on by accident. If its not on your remote, then it is in the menu. Good Luck Ps Please dont forget to rate this thread.
