Tv screen black

[bettyboopyu100]

I pushed a button on my remote. Now I got a black screen in the middle of my picture. How do I fix this?



Try power cycle:

Switch TV off.
Unplug TV from mains socket.
Plug it back in.
Switch TV on.

Maybe you turned on picture in picture? Without listing the TV brand and model tough to know what it may be.
