If you have a Texas Instruments TI-83 Plus that is no longer working, you can first try replacing the 4xAAA + CR1620 3V 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.
