Nintendo Switch Lite Right Joy issue

I’ve a Lite with a right joy issue. Even after several replacements the joy is always pointing up. Therefore I assume there is some kind of sortage. I tried to clean joy flex calbe and connector with alcohol, but no help here.
Do anybody know how and where to messure joy sortages? Or do anybody have a motherboard blueprint maybe? It would be really helpfull.
Of course i tried to ccalibrate the joy, but when I start the process for some reason it won’t to reflect on my movements (pressing it to the right doesn’t move the cusrsor to right corner of the circle)
