RE: Elektronika MK-61 operation?
Dim displays are a common "failure" on those calculators. 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...
