So I have a Nintendo Switch Lite that had a broken USB-C port and a shorted M92T36. I soldered a new USB-C port and M92T36 chip and the short is gone, but still… no power and it wont charge with the OEM charger.
Before doing the job, I tested the USB-C with a breakboard and all values were good (compared to a working NS Lite) except for pin CC1 and CC2, which should read 0.538 (Diode Mode) and I was getting “0.000”. After installing the new USB port and M92T36, it keeps reading 0.000.
I tested for continuity from pin CC1 and CC2 from the USB-C connector all the way to the M92T36 which pin #35 is CC1 and pin #37 is CC2. There was continuity. I tested in Diode mode too and was getting 0.000 again.
Checked the fuse and charged the battery with another working console an both are ok.
Checked bq24193 for shorts and theres no shorts.
I don’t know what else should I do next.
Also I want to add that while changing the M92T36, I damaged a small resistor that connects to the pin 22 (S2_DRV_SRC), but I don’t think that is the problem since the issue is the same since the beginning and now there’s no shorts. I used my thermal camera and also didn’t see any hot spots.
