Blach rectangle bottom halfpart of screen

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.

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!!!!

Try Reseting It Unplug It For 30 Seconds And Then Release And Plug It Back In Once You Go To Turn It On Hold The On/off For 10 Seconds and Then Release. This Will Hopefully Restore The Factory Setting And You Can Determine If Its A User Setting Or Hardware Problem.

The box you're seeing is the "closed caption' box. You need to use the remote and disable CC mode on it, and the box will go away :)

captioning on turn off with remote.

Your DirecTV signal is probably too low. That would produce the small black rectangles (pixilation). Also, try replacing the cable you are using to get the signal from the DirecTV receiver.

If the black rectangle is in the middle'please check to see that the closed caption is not activated.If not please provide the location of the rectangle.

I'm not sure what type of TV you are using,, but most all Large Screens have a reset button someplace. You should be able to reset the TV and fix the problem. Its not the remote, making the image appear, but a command from it was misinterpeted. Sometimes turning the set off will work, but most often it needs to be reset.

EXCEPTION... if you are using a cable box. Disconnect it from power, wait 1 minute and then see if the problem exists. If the cable box is on even with the DVD you may still have this issue. Please reset the cable, and if that doesn't work, reset the TV.
Thanks! //D

This type of problems and some OSD problems are occurs due to microprocessor over modulation. One option is there. That is if you have any child lock or keypad lock or frontpanel lock. First locked the system. Now check your problem arise. If it is not OK. Otherwise try to find nearby any radio frequency cable across in your tv. keep away that cablewire also. your problem solved. Even you get Call your nearst service provider..
