How do I fix my calculator that only runs on solar power?
My Casio fx-991ES PLUS was dropped and now the display does not light up unless it is under a light source. It has a mini solar panel which I assume it using for power and it has new batteries in it but they do not seem to work. Is there something I can do to fix it?
Is dit een goede vraag?
