MY calculator won't turn off except after being left alone for a long period of time and the buttons aren't responding. Also it only displays 0=. and I've even tried restarting it many times.

Hi,
Try replacing the battery and then resetting the calculator.
The EL-531X uses a LR-44 (or equivalent) battery
Here are two images that show what to do.

Hi. After changing battery and resetting, all the buttons still didn't work. Please help.
I had the same problem and managed to fix it by removing the battery and unscrewing and removing the back cover. That's it. I reckon that the issue happened because the "=" key connection was stuck, so uncovering the calculator might have "released" the connection. Hope this helps!
