Basically what the title says - I have replaced the battery in my son's Switch Lite, but to no avail. I really would love to be able to effectively diagnose and replace whatever part needs replacing. I have the means with which to solder and replace pieces on the PCB if that's what it comes to. I just don't know how to diagnose each specific part of charging a Nintendo Switch Lite. There are so many components on the MB and I have no way of knowing which ones to check. I have a multimeter, I have magnifying lenses, etc. Can anyone help me get started? I don't want to desolder the USB-C port if I don't have to. I'd rather start with diagnosing first and then replacing as a last resort. Any help is appreciated!
