Why is my screen fuzzy?
So, my calculator won't turn on and when it does it displays a fuzzy screen that kind of looks like a bar code or something. Then if I hold alpha and press the on button sometimes it pulls up a menu for a F1-F5 thing. I tried taking the batteries out and just about everything I can think of can you help me
Can you take a picture of the screen on the calculator and upload it here? 在已经存在的问题里加入图片
