Hi, my son’s Switch won’t turn on or charge. I replaced the battery, and in doing so, damaged the SD card reader, so I replaced that as well. Since the new battery came with some charge, I can be sure it is not a display issue, as the display worked, but on connecting the Switch to the official charger (directly - no dock) there was no indication that it was charging. I have attempted to charge it over several days with no effect. Other than the battery, what other replaceable points of failure could there be? And how would I best test them to isolate the issue?
Here is a list of components that can cause a Switch to not charge: Battery Charging Port Charge Chip Various other chips, diodes, resistors, capacitors, etc. on the motherboard As Raffi said, you would need a multimeter to check to see if these were bad. You would also need a hot air station, flux, solder, and a soldering iron to fo these other motherboard-level repairs. Another thing you could do is to replace the motherboard. However, a new motherboard will cost about $180.
