I bought a Nintendo Switch on eBay that doesn’t power on.
I have tested it with the USB tester that Steve uses.
It shows .4 amps on the tester, but shows no charging icon on the screen.
I took it apart and there is no liquid damage or corrosion.
I tested the chips and fuses with around the charging plug with multimeter and there doesn’t seem to be any shorts.
I have also replaced the battery with a known good battery, but nothing changed with the new battery.
I have also left it plugged in for over 24 hours with no change.
What can or should I check or replace next?
Thanks in advance for your help.
