The processor could be corrupted, since you've used it in the past to balance your checkbook, and now you can't achieve the same results. Unfortunately, over time, physical chances can occur with the minute electronic circuitry Sometimes, you can take the calculator apart and clean the circuit board with alcohol, check for cold (cloudy) or cracked solder joints, and resolder them. Toluene is the best circuit board cleaner, but it's no longer available over the shelf.
There could be a mode setting to allow this, and you might check your manual for things like "Checkbook balancing" or any other reference to "Checkbook". I have a similar model, and will have to find it in storage (wish me luck), and will post back if I can verify the keystroke sequence necessary to achieve your correct balance. Here is a link to the manual, in case you've misplaced it:
Good luck, and hope this helps, and I will post back if I discover the keystrokes.
