I have a joycon having pin5 staying at high when it's plugged into the switch.
I need to manually short it to ground to bring it to low, then the switch sounds "click", and the wired connection is done.
Once the joycon is disconnected, it goes to wireless mode.
When it's connected back, pin5 stays high again.
This joycon is left on the shelf for long time because of its broken connector.
I took it out for a repair a few days ago and successfully soldered the connector, with 2 soldering pads gone.
So the 2 pins (pin 3 and 10) were connected through a jump wire instead.
I have all test points and ground continuity tests passed. The connection seems to be fine.
I'm also quite sure that the switch's rail is fine because it can detect other joycons without issues.
Which part should I try to investigate?
Should the chip died somehow?
Is it possible for me to keep pin 5 shorted to ground to make this joycon work? Will this cause any further issues?
Thank you for all the ideas!
