I have repaired a few switches in a row before, and I bought a broken switch for 11,000 yen. I thought it was a switch that could kill in seconds, but I didn't expect it to be faulty. From the tail plug to the tail plug pad to the usb chip and finally the cpu is found, they are all faulty. . . The usb pin of cpu has no resistance. Have you ever encountered it?
