A black box shows up in the middle of the screen on some channels

Maybe pressing the SETUP button the remote will get results.

Closed Caption function to that channel you select is ON. Make it OFF, when you are in that channel which displays this black box. It will be best to reset the TV to its factory settings first, and then re-tune it. for more details, refer its user manual.

Try website like Remotes.com to buy the tv original remote to used.U will used the tv original remote to turn to channel 3 with ease.After u have the tv original remote push the menu button go into Closed Captioning functions turn off like TEXT 1,2,3...The big black box will not appear on the screen again.Tv used it manually control buttons up and down channels trying to get to channel 3.U will never get it to tv channel 3 because tv channel 3 was not save on it memory list of on the tv turn manually channels buttons programming memory.Tv have a manual button said MEMU button on it tv front bazel frame?Yes.Might could used the Menu button on the tv frame to get in to turn off TEXT 1,2,3...to stop the big black box to show up on the tv screen again.

IF YOU, STILL SUBSCRIBE DIRECTV, YOU MAY GO TO THE MENU, USING THEIR CLICKER AND GO TO THE PART OF MENU, WHERE YOU CAN CHOOSE TV TO OPERATE WITH DIRECTV REMOTE. YOU WON'T BE ABLE TO CHANGE ANYTHING ON TV BY USE DIRECTV REMOTE, BUT TO OPERATE IT'S CONTROL BOX. REALLY, YOU CHANGING CHANNELS ON THAT BOX, NOT TV ITSELF. IF YOU'RE NOT A SUBSCRIBER, FORGET THAT REMOTE! UNLESS YOU'RE A CUSTOMER, IT WON'T HAPPEN. JUST "GOOGLE" YOUR MAKE AND MODEL FOR A SUITABLE UNIVERSAL REMOTE, OR THE ORIGINAL.
ALSO: YOU WON'T BE ABLE TO GET ANY RECEPTION(HD OR ANY), UNLESS YOU HAVE RABBIT EARS OR ANTENNA ON A ROOF.
GOOD LUCK,
ALEX'S TV.

Look on Amazon for a pattern dedicated remote for your tv. They aren't expensive and will allow you to access the set's menus.

your closed caption is on, this might be set on the cable box or the tv, look in the audio or set menu. If you dont have the remotr you should be able to navigate the menu on the tv with the onset controls

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!!!!

Turn off the text box function of the closed captioning.

my tv was working fine. somebody hit the menu button on the tv or the remote and i get the black box appearing in the middle of the screen. and also the pip is staying on my tv it keeps showing "a snowy picture of pip sjpwomg channels 2 through 18 i cannot figure out how to get this off of my screen.

You have CC (closed captioning) turned on and it is set to text mode.....Go to the menu on the remote use the right arrow and hilight "C.CAPT",use the down arrow to highlight "C.CAPT",use the right arrow and highlight "off" then exit button on remote.
