I have a 42" plasma LG TV and on some of the channels the picture changes in that a black box appears occasionally. When it appears, it will disappear if one hits any button on the remote......
Go into the menu and look at the closed caption option----if TEXT is highlighted--this is your problem---select CC! or if it has it OFF.The TEXT will only appear on certain channels and it most likely was activated by someone changing the closed caption options. If this has been helpful give me a vote to let me know.
