Got a water damaged switch and im getting 3.3v and usbc voltage to m92. pi13 cap is getting 3.3v. Water damage near oled connector and fan. Im only getting 1v on fan pin 2. It seems that the 5v rail is dead or missing as I don’t detect it on the transistor leading to joycons. I can hear some pwm sounds of a power supply straining and restarting.
Where is the 5v rail generated?
