Hardware Right Joycon won't change to single-joycon (horizontally)

[xXDungeon_CrawlerXx]

Hey Guys,

after long time, my right joycon seems to be fucked for no known reason.
It totally works like a charm when connected to the Switch.
Also the joycon still works via Bluetooth when using the BOTH-Joycon mode.
But when I want to connect both joycons separately (by pressing SL+SR), only the right joycon doesn't want to change into the single-joycon mode.
Also the LEDs doesn't seems to blink anymore on the right joycon.

What I've tried:
- Restart the Switch
- Disconnect and Reconnect both Joycons to the Switch
- Update Joycon Firmware

It still doesn't work.
Here's a video I made to show the problem.



Any Idea how to fix that?

Go to Settings and do the test for the buttons on the right joycon, even if sync'd as vertical it should show if you press SL or SR. If one is not recognized then there is your problem.

If the lights aren't working either then you might have a ribbon cable come loose, or damaged. Shouldn't be too hard to fix if you get the right screwdriver, and if the cable is broken the easiest fix is to buy a whole new rail part with cables, they're fairly cheap.
