Hello. I got a nintendo switch that had obvious damage to the p13usb. There was a hole in it, plus the two inductors circled in red in the image were burnt. After replacing the components the switch was running for a few days then returned with the same issue. Swapped it out again (thinking it would blow again, but couldn’t find any other issue). It returned 2 days later. The p13usb was blown in the same spot (marked in red). The inductors seem to go directly to the usb c port, but the client is certain that nothing was connected to the switch at the time it blew the second and third times. This last time It was just sitting on the table while they were eating and suddenly it shut off by itself. Does anyone know what could cause this if nothing is connected to the switch? I would have guessed it being the dock or charger, but the dock hasn’t been used since the first swap, and the charger has been used on other switches just fine. Any help in diagnosing would be awesome. Thanks.
Edit: Seems the forum wont let me add pictures nor links to pictures to show the damage. The inductors burned are the leftmost ones, labeled as lines sbu1 and sbu2 in the diagram I found on this forum.
