Activity Button UI Interface Board
The failure is localized to the mechanical interface between the translucent button plunger and the PCB tactile switch. Over time, particulate ingress from the internal drive-train's rubber rollers or structural fatigue of the silicone switch membrane causes the button to remain in a closed-circuit position. Replacing the UI board and plunger assembly restores the necessary mechanical clearance and spring-return force required for operation.
