Re: Black Box at bottom of screen
The text mode has been activated either thru your cable/satelite box or your tv's. It is activated because the closed caption portion. If you think its because of your channel providers call them for the process to deactivate it . If it's your tvs check your menu's to make sure the closed caption portions are turned off. Good luck

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---
Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.
Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.
Check your closed-caption settings. You will probably find that you have captioning on and set for "text" mode. Turn it off and the problem should go away.
What's happening is that with text mode on, the set clears an area (the black box) for text to be displayed, but there's no text. On channels or programs where captions aren't being broadcast, you don't have this problem. Most TV remotes have a button for quick access to caption settings, so it's easy to get this turned on without knowing it. Then you're suddenly facing the black box.
Please take a moment to give this solution a fixya rating if it gets your box cleared up, and thanks for asking here!
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.
It sounds as though the closed captioning has some how gotten turned on. Not all programs are closed caption supported so the box will not show on every channel nor will it necessarily be on the same channel all day. Go into the menu on the tv and ensure the CC option is turned off. You may have to go into set up or preferences to locate the CC portion of the menu. I hope this assists you and thank you for using Fix Ya. If I can assist you further please let me know.
By your description it sounds as though the closed captioning option has been turned on on the TV. Only certain programs are CC capable and that accounts for the box moving from channel to channel as some broadcasts are not CC CAPABLE. Go to the menu on the tv and ensure closed captioning is disabled. This should resolve the issue. If you need more help please let me know.
Just happened to see your black box problem associated with your T.V.; Thought I would pass along an idea for you to check into, and let me know if it helped...Check into whether or not it has a onscreen text block mode, if it gets into this mode by accidentally pressing the wrong buttons on the remote and or TV, it could and I have seen, at least with zeniths, a big black box which will cover the whole screen except for a 2 to 4 inch border around the box and outer edge of the screen...if this is the case, find someone familiar with the correct setting for the set associated with this problem, and get it back into the right mode....Hope this helps..T.
I have a Sharp Tv that had the same problem with a large brownish or black square right in the middle of the screen. It only left about an inch around the edges that you
could see the picture moving in behind the big black block or square.I have DISH sat-elite and the book recomending that I check and see if the "caption settings" were on
or off. They were on. I turned the caption settings off and the large square diappeared.
