I’ve got a switch which is not showing the snap animation on the right joy con but connects fine otherwise. I’ve found out that the problem is not on the rail itself since I swapped it with another switch. I went over the board in diode mode comparing the values with a known good board. I found a short on the “PU” labeled diode (see image). I’m a bit puzzled how this diode can short to ground, since I don’t see any ground going into this diode. Is there a ground pad underneath or does the shorting section connect to somewhere else? I checked all around and couldn’t find connectivity to somewhere else. I guess I’ll have to take the diode off but I don’t have a donorboard where I can take it from. Does anyone have information about this part which would help me acquire a new one?
Thanks in advance!
