I have a Nintendo Switch V1 that turns on but does not charge.
When I connect the charger, it is detected but does not charge.
When I check with a tester, I see that it only has a consumption of 2V - 5v and 0.5A, not 12V.
This Switch was brought to me because initially the pu3usb and an EMI filter next to the track burned out.
It was replaced and the board turned on. I noticed that the Switch was not charging and replaced M92T36 and it charged without any problems.
A few days later, the board had exactly the same pu3usb failure and the filter was damaged. I replaced it again and, to my surprise, it still doesn’t charge.
I already checked the port, capacitors, and MOSFETs, and there are no short circuits.
Can anyone help me and tell me what’s wrong or where to start?
Do I just have to replace the M92T36 and it won’t fail again?
