I just picked up a Switch. It clearly at some point got liquid in the right joycon rail, as it was seriously corroded. I have tried to clean that one up, but for the sake of making sure everything was working replaced it with a new one (Brand new part).
With this installed, the Joycon itself is detected, it shows as both charging and connected to console, but it does not play the connected animation / sound.
I have done my googling, and knows causes seem to be:
- Firmware lower that 9.1.0 - It was already on 9.1.0, but have now updated it to 12.0.0, with no change.
- Dirt on pins - It’s a new rail, and have tried with different right joycons. Gave it a quick clean anyway - no difference.
I also connected a new rail from a joycon to it, so I could test for continuity all the way through, and I seemed to get a connection to somewhere from all pads on the joycon side to the connector in the switch. I also checked for loose pins at the switch connector.
As far as I can tell, everything looks fine. Does anyone know if there is anything else I should try? I have ordered another set of rails, just in case the one I have is bad. Is there a specific pin that is required for the snap animation?
Thanks in advance!
