Hello everyone, as the title mentioned i own a Casio Fx Cg-20 which i use in my classes and it's backlight is not working. The screen itself is working as i can see it working with enough ambient light. The brightness setting is obviously useless here. Batteries are fresh too. Does anyone have experience with these things or can maybe identify the problem just by looking at the board? I should add that the backlight works occasionally, for example, it worked for like 15min. after i put fresh batteries and it also sometimes worked when i took out the old batteries and put them again. The calculator also showed 2/3 battery before i replaced them so battery problem is out of the way i think. Thanks in advance.
