Hardware Left joycon not detected

[Sinail]

Good morning,

I'm taking the liberty of coming here because I have a problem with my switch, the left joycon was not detected in the rail but this one is loading well. Do you have any idea where the problem could be coming from?

Thanks in advance

Check the rail and try a second left joycon if you got one.

Vérifiez le rail et essayez un deuxième joycon gauche si vous en avez un.

Hello, I have already changed the rail and tested with another joycon

The rail has been changed twice, I charge joycon on the rail but did not detect it, I think the fault comes from a component on the motherboard, if anyone has the circuit diagram of the part joycon on the switch motherboard that would be great. Or simply an idea of what component this could come from.

Thx

Have you checked that the ribbon cable connectors for the Joycon rail are good? They might be corroded.

Hi,

I'm talking about the connectors on the joycon board.

I'm talking about the connectors on the joycon board.

The joycon was tested on another console and it worked, I also tested 3 joycons on the console and it did not detect this one. Sincerely
