I know about changing the contrast by using 2nd and Up and Down arrows but my screen is black and i can't press any keys. None of the buttons on the calculator even respond, i can't even turn the calculator off. I have to pull out the batteries to get rid of the black screen. Anyone know how to get rid of the black screen?
