Replacements:
If you have a Casio fx-7400GIII that is no longer working, you can first try replacing the 2xAAA + CR2032 batteries. If that doesn't solve the problem, then a repair might be possible, although you have to weigh up the costs against just buying a new one, as this model is still currently available.
