Some channels on my tv have a black screen.

There is a black square that shows up on some of the channels on my tv. It doesn't cover the entire screen but most of the screen. What could this be. And how can this be fixed?

A black square in the middle of the screen

Closed caption function is ON with your TV. Make it OFF.

The TV is a Mitsubishi CS-26201C to the extent it matters and the remote is the original remote. A small child played with the remote and now a black square pops up and covers vitrtually the entire screen...

The child managed to press the button on the remote that controls closed-captioning, and now the TV is set for "text" mode. I don't remember if the button says "caption" or "cc", but it's one of those or something very similar. Press the button again to go through the settings until you get back to "off" and the box will be gone.

What's happening is that in text mode, the TV blacks out the area where the text would go. If there isn't any, the result is that mysterious black square. It may not show up at all on some channels, or only during some programs. It depends on whether captioning is being broadcast. Since many TV remotes have a single button to control caption settings, it's easy to get into this mode without realizing it. But it's easy to fix.

Hope this helps! Thanks for using Fixya.

Large black square blocks screen

Most likely it's the closed captioning has been turned on. From your post I assume you have the remote control and able to access the menus so try to turn off the closed captioning. I'll be notified if you post something new.
