You might try to measure the voltage between the centerpin of the
potentiometer and ground.
Check, whether this voltage changes, if you turn the potentiometer.
Then track the copperline from the centerpin on the pcb whether this
voltage is transported correctly to the socket of the CD4051 and also
check whether it appears at the IC pin itself.
