check your closed caption, long time ago there were 4 cc options. Turn it completely off, that might get rid of it.

Yes your text mode is on in the closed caption menu. turning cc off or reseting cures problem

you have to use the remote to turn off the closed caption. But I am sure that is the problem

I would check and see if you have the text option on under your closed captioning. With the new digital transition the signal for text captioning has been getting messed up during broadcast here lately. If it is on i would just shut it off or go to regular closed captioning.

This is a problem with closed-captioning. What you are seeing is a closed captioning box with no captioning in it. Usually this is being accidentally transmitted by the cable company "head end". Just make sure your closed captioning function is completely turned off. if you are seeing it randomly, it may well be coming from your cable company. Is it just on certain channels?

shut off close caption. use the CC button onthe remote or go in to the menu and change close caption to CC1. this box is the close caption in TEXT(1,2) which will put on a black box whenever there is caption present.
