Steve,
So as an electrical engineer that worked when there were a lot of potwntiomers (pots) used, The pot is the weak point in any design that employs them. They are usually a carbon emulsion on some plastic base. They have problems over time. Tapping them or slightly moving them re-establishes connection. Pulse Width Modulation (PWM) controls can go out of range with bad input. The result could be zero pulse width, which could be off to some displays. However, like the engineer said, if voltage from the E-lite module is bad, it'll go off too. These are all just places to look. If it is flickering, check the voltage on AC, assuming you have a meter that reads auto ranging frequencies or an oscilloscope.
Regards,
Bob
