Question about Texas Instruments TI-84 Plus Calculator
I was randomly pressing buttons on my calculator and i randomly held down 2nd and up and it went to this black screen and no matter what I do (like turning it on/off, or taking batteries out) it won't go back DID I BREAK IT, MY DAD'S GONNA BE SO MAD!!!!!
You darkened the screen. The solution is to lighten it.
Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key for a few seconds.
