The most likely cause is incorrectly placed batteries. (I know it from experience: It happened to me too).
Unlock the keyboard and remove it. Look at the polarity diagram on the body of the calculator, inside battery compartment. The positive terminals are towards the bottom.
To darken the screen press THE CTRL key and hold pressure. Press the + key until screen darkens.
