Nintendo Switch sent from Taiwan, the resistance (voltage drop) of each cpu is normal, but the output voltage of the main power supply is abnormally high, and the boot current is large. Tried various methods and couldn't find the reason. Replacing the CPU confirmed that it was a problem with the motherboard. The point is that two machines with the same problem were encountered within two weeks. Could it be said that this failure only manifests itself in a hot day? Although, this machine was repaired by moving the board. Please help me analyze the cause of the failure. . . Hope to fix that motherboard
