If it was a connection problem, it might be working again. If not, do you have a Multimeter with diode tester? That is perfect to check if all display segments work.

Thank you for the instructions on dissembling the calculator! That was easy enough.

I unplugged the display from the board, cleaned the contacts, and then set it back again. Problem persists.

I do have a DMM with a diode tester, although I have not used that function to-date.
