Hardware Bought a switch on ebay which can't be powered on

[Seelbreaker]

So i bought myself a defective Switch in the hope that the switch just boots into rcm or and could be easily revived since i want an online Switch for myself.

But i got not that much luck.
It won't charge, the console has been opened already but on the first look there isn't something destroyed.


Since it won't charge i think the first thing would be to check if i can get a current from the USB-c Port after plugging the charger in and looking if the current is getting to the battery - right?
I've got a Voltcraft V100 Series Multimeter but need to lookup how to check something, because my knowledge in electricity and such stuff isn't that great - but i can and would gladly learn by getting this one to work.

Do layouts exists which could tell me which circuit points etc. i need to additionally check? I bet there won't be just a direct connection from the USB-C Voltage Ports to the Batterypack...

If needed i can also try to get some good pictures from the switch and Multimeter readings.

Many thanks!


PS: If Hardware is the wrong section for that please feel free to move it somewhere else.

Thanks for the video! This is pretty much perfect for me to get some guesses and hints as where i should look first (especially i should take a better look on the chargeport again )

Also this usb-charger is pretty neat!

i was just about to link to the above videos too.
he has plenty of switch repairs vids, plenty of things to check

Yeah, already bought flux, a heat "cannon" and the usb voltage tester which will come tomorrow.

Then i can for myself check what i need to setup on my multimeter to get the same charging value as the usb-tester But atleast i can do some ground-checks on the resistor.

I assume those chips and resistors can only bought on chinese websites right? Like i need to search for those resistor and IC names. Or do i need some defect consoles as spare-parts?
