Why does a black square pop up in the middle of the screen?

Hi Tony

You`ve mentioned that ON CERTAIN CHANNELS THE TV WORKS FINE, so your trying to say that not all channels THE BLACK SQUARE APPEARS IN THE MIDDLE O THE SCREEN... my be that black square is generated from the broadcast center. may be your unit is good. let me ask you how many channels that your tv works fine..?

U have the tv original remote wright?Yes.Used ur tv remote look for a button that said CC.Pushes a few times make sure all like CC1,2,3 so on to all off.The black square box show up in the middle of the tv screen,numbers and printting words on the screen it is are call Close Caption for the hearing impair person to read,will disappear from the middle of the tv screen.

How big is this black square? Is it like 1/4 to 1/2 the size of the screen? If so, you probably have Closed-Captioning turned on, and turned on to TEXT mode. Either change it to CC1, or else turn it off, and your black square will go away!

Turn off your Closed Caption, it's in text mode.

It is most likely related to the Closed Captioning option on your TV. Go into settings and make sure that CC is turned off, or make sure it's set to CC1. What you are probably seeing is the "text" option included in the CC options.

turn off the closed captions - you have it in text mode that will have a big black box with video on the sides
thanks

the black sq stays all the times

It sounds like your panel is going out and time for a new TV

Mark, Stupid me did not buy the additional warranty that I could have.. I have bought warranty on every television I have ever bought, and never once did I even need it. Even til this moment I still have the reg tv's and they all work great....On this flat screen, it isn't always this black squares pop up. I might also add, they do not stay in one spot. one moment it will be flashing at the bottom, the next it might be at the top or in the middle...then it waont do anything for weeks....any Ideals??????thanks for trying to help[

He, he. Somebody activated the subtitle mode on the remote. Desactivate the CC mode on your menu and it'll go away or at least if you want CC put it in CC1 Text1
