Joy-Con Sensor Rail (Console Side)
The console-side rail contains a series of delicate pins that interface with the controller. Repeated insertion cycles cause mechanical wear or displacement of these pins, breaking the electrical 'handshake' required for handheld mode. Replacing the rail restores the physical and electrical bridge to the main logic board.

Joy-Con Internal Slider Rail Flex Cable
Internal to the Joy-Con itself, the ribbon cable connecting the slider rail to the controller's PCB is subjected to a 180-degree fold. Over time, the copper traces within the polyimide film suffer from work-hardening and fatigue-induced cracking, resulting in a total loss of wired communication.

Joy-Con Controller Assembly
In cases where the mounting substrate of the controller has warped or the male connector housing is physically damaged beyond component-level repair, a full replacement of the controller is the only reliable method to ensure proper rail alignment and connectivity.
