BRIGHTNESS & DISPLAY ADJUSTMENT. MY "T" DOESN'T WANT TO PRINT SOMETIMES

I can't adjust my brightness or display size (print) in Windows 10 (my version has night llight selection which isn't hot so I can't turn on or off ) no brightness option. No print or font size option either. I also have a hard time getting my "t" to
type when using my keyboard. Sometimes It works and sometimes it doesn't. Any suggestions are welcome.
