On NBC football, closed caption in Spanish on top of screen.

Inside the set is a block with a big red wire attached to it, that runs up to the side of the picture tube. On the side of this block are two controls. One will say "Focus" or have an "F' by it, and the other one will say "Screen" or have an 's" by it. With the TV set one, slowly turn up the screen control till you see thin white lines in the picture. Then back it down till the thin white lines go away. Rock the focus control back and forth to adjust and tweek the focus. You may have hit or moved the controls when cleaning the TV set. Be very carefull and please dont touch anything else, as there is alot of HIGH VOLTAGE inside this TV set. If that does not work good for you, unplug the set and make sure all of the plugs and connectors are pluged in straight and in all the way. Good Luck and let us know how you made out.

Some how or some one switched on the closed caption feature in the set as thats a text box.. your going to need the original remote to turn off the closed caption by pressing the c button.
 

Click the c-button on the remote to turn the caption off

Have you tryed changeing the setting for CC on your cable box or tv.
