Usually it's the electrolytic capacitors in the voltage regulator that are failing (that also caused problems with EEPROM use in the landscape model). I've fixed a few by replacing the capacitors, but you have to be careful since the boards are very cheap, and it's very easy to lift the traces...

Since I can't use the calculator as-is, I have little to lose by trying to replace the caps. What values(s) do I need?
