I managed to repair some Nintendo Switches - thanks to you guys and the information here in this forum.
A few weeks ago I got a Switch which had a blown pi3usb and two ripped pads. I soldered jumper wires and replaced pi3. Everything seemed to work for a few days and all of a sudden the Switch didn’t power on anymore. I then replaced the orginal usb port and the switch started powering on again.
However whenever I place the switch into the dock or plug the 15V charge cable into the switch, the switch shows the error code 2101-0001 and prompts to reboot. This does not happen with a 5V charger. Today i replaced the pi3usb again and also M92 but still the same behaviour. Also the CPU gets quite warm (in compare to other Switches) when powered on.
I checked some of Calvins diode map readings and could not find anything obvious as well as no shorts around the usual ICs.
I can provide some pictures if needed.
Do you guys have any ideas on what to further check? Thanks in advance!
