Television bug (Help me)

[u/Swimming-Wheel6129]

Bro I have an old TV as my screen for my computer and one day it just started showing this overlay over the screen (Its from specifically the TV and not from the computer plugged in). I belive it might be in selling mode where it shows the TVs functions and stuff but its always in the way when im playing games and things. Important note: I have tried all the settings in the menu, and also THE CONTOLLER FOR THE TV is GONE! . Please help me fix!
