Problem description
Fixing an issue where the Joycons are not charging or connecting/pairing. Joycons aren't charging (on one or both sides), the fan works, and the side-rail is confirmed working.
Symptoms
- Joycons not charging or connecting/pairing
- Joycons aren't charging (on one or both sides)
- The fan works
- The side-rail is confirmed working.
Solution
Measure both resistors. 18kohm on both resistors (Figure 1) indicates a failed/shorted capacitor (even if the cap does not test as a short). Resistors should measure 100kohm and 22kohm respectively.
Measure pin 6 (Figure 2 & 3) in diode mode-- it should read 0. If it reads 0.6v drop this reinforces the capacitor failure.
If resistors check out, the DC-DC component may need replacing
