Re: The screen is black and not allowing me to do...
Try adjusting the contrast. Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key for a few seconds and see whether the screen lightens.
If that doesn't do it, please append a comment to this post and we'll go on from there.
