Nintendo switch oled joycon right no communication

[xiran64]

Hi to all!

I have a switch oled, wich can´t communicate the right joycon with the console.

Things i did it:
Put joycon in another console:
Joycon recognized.

Put another riel
Didn´t work.

So i thing is a problem in the mother board.
I´ve checked this page:

https://www.retrosix.wiki/joy-cons-nintendo-switch

But i don´t find info about the mother board, related to the joycon managed.

Somebody have something about this problem?

Thx in advance!

Is the flex cable for that joycon inside the Switch in working condition?
