BLACK BOX APPEARS IN LOWER HALF OF SCREEN. It GOES AWAY BRIEFLY WHEN CHANGING CHANNELS or adjusting settings.

Check your TV settings under Caption, odds are someone adjusted the captions to text1 or 2.. the box should go away after you change that to off or std cap.

Check your closed-caption settings and make sure it's turned off. You'll probably find it's now set to text mode. The set is blanking out the part of the screen where text would be displayed, but there isn't any.

Go into the TV's closed-caption settings and turn off captioning. You'll find it's set for "text" mode right now. What's happening is that in text mode, the set blanks out the part of the screen where the text will go but there isn't any. On channels or programs where captions aren't being broadcast you don't see anything. With the captions turned off the box will go away.

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.

This worked on my tv...give it a try:

Try and turn off the closed captioning. I had the same problem and it turned out that the closed captioning was on t1 instead of OFF. Hope this helps!!!!

Note that the large black box goes away when pushing buttons on the tv (ex: the black box will disappear to show the volume setting when changing the volume on the tv but it will cover the picture and the menu display of the dtv box).

This is caused by the closed caption setting of the television set NOT the captioning of the converter box. To fix this you must open your television's menu, find the ccd/closed caption option, and turn it off. This is a frustrating problem as when most people are told to shut off the captioning they try to do so at the box.

Normal dtv box captioning will appear as a small text box at the bottom of the screen as you would expect - not as a giant black rectangle that covers most of the screen. If you do want to shut this off too you will find that you can't do it through the usual menu options (the menu will only allow changes to font, color etc.) - there should be a ccd button on the remote that when pushed will scroll through ccd-1, ccd-2,... off.

Try turning off the text box function of the closed captioning.

Well if you have anyway to get in to the menu of this set you have to turn the closed caption off, It is turned on to "text 1" and this causes this problem

Perhaps the caption is on?
