On a few channels a black rectangular box appears after the set has been on a short period, less than a minute. You can switch channels and come back and it is ok for a few seconds, then the box comes back.Again this happens on a few channels.
It's the Closed Captioning function I think. I've had the problem with my Sharp TV (and other TV's that have Closed Captioning function). Look at the menu or the manual to see how to turn off Closed Captioning. It might be marked as "CC".

You must unplug the cable connecting the television and the cable box. Then turn the television off and then back on. Do not turn the cable box off or disconnect the cable in wire from the cable box especially if you use Cable Vision. It will take up to 20 minutes before the box comes back on. Now turn the television back on. When you access the Channel System menu, you have the access to the submenu choices. Change the Antenna option to CATV and the Current Channel to 3. Reconnect the cable box to the TV.
Also those that are having problems with the TV turning off periodically, make sure the sleep mode option does not have a number in it. For example, if the number is 10, it will turn off every 10 minutes.
go into your menu and find closed caption, someone has accidently set the closed caption mode to text, when the on screen display of channel or volume goes away the box appears. turn off the closed caption feature or switch it to something other than "text" mode, and your box will go away.
