Not a problem
Rather annoyingly i did this repair not that long ago but failed to document where everything went (at least on this joycon side)
The reasons for failure here ties back to a reply i made on another post, where somebody incorrectly installed a replacment USB causing this tail end to bow out - but also overwork of the BQ chip both in turn causing via damage (due to swelling)
Symptoms were, failure to show the snap (animation) and i think failure to charge, but the controls seemed to function fine on the joycon, as a result of no continuity at certain spots, i had to snake three enameled wires in total (from memory) from the other side of the board up and around to the IC in the picture to resolve the issue as there was no other point to link to, and i believe also a resistor near the fuel guage.
Assuming the joycon that is giving you the issues is the same side as in the attached pic? can you give resistance readings on the IC in both directions and tommorow i’ll provide a continuity map if needed.
If it’s the opposite side that’s giving issues, i will have remember how i solved that… was a long time ago i had the same issue on the otherside.
