There are others on this forum who have a greater knowledge of this, and may have some ideas. The only thing I can think of is that the capacitors that are used in the LED circuit may be weak, and although the calculator ICs are getting powered, the LEDs are not. Why removal and then re-installation of the battery pack fixes this I do not know. Then again, I could be completely wrong on this, so it is just idle speculation.
