Did you thoughly clean the wiper-arm tracks?
Did you conduct a post-mortem on the removed resistor?
I did so on mine when adjusting the ASA didn't have any effect.
You can use a high-meg digital multimeter to measure the resistance changes at each little segment. It only takes one bridge to be low ohms or open circuit to stuff up the entire facility.

Unlikely as it may sound, Murphy's Law is ubiquitous and given the propensity of this component to malfunction it could be that your replacement parts stock wasn't too flash ??? If the resistor is sound; the wipers stroking properly and the wire soldered joints good, the meter just has to see the input variation.

With a fresh new battery in situ have you checked the voltage output at the resistor - and for variation of such as you change the wiper position in small stages ?
