All I get when powered on is a black square that is gridlike. No other controls work. All 5 batteries are new. How do I get it fixed. My location is Reseda California 91335


Try to lighten the screen reolution. Turn the calculator on, press the 2nd key. Then hold the down arrow key. This should lighten the screen. You can darken the screen also. The only difference is hold the up arrow key down until it's dark enough.
