Question about Casio FX-9860GII SD Power Graphic Calculator
I changed all the 4 AAA batteries but still the same. what might be the other problem please
You can try to increase the contrast of the display.
Use the right arrow to increase contrast. If there is no change, the calculator may be damaged. But do a calculator reset just in case
