/diy/ - Do It Yourself

I don't know if I should post here or not by I literally have no idea where else I should ask so any help will be appreciated.

My Switch console died after being thrown by a retard (no, not me).
I took it apart and the motherboard seems okay and the battery still has voltage, also the console is still charging (checked with a multimeter).
But it doesn't turn on, no indication on the display whatsoever that it's charging and no sound coming from it either.
Anyone have any idea what's wrong with it? I tried Google and YouTube fix it guides but that was no help.
My next idea is to buy a replacement screen and see if that one lights up or not cause I have no idea how to check if it's broken or not.
