Hello,
I have a New 3DS (non-XL) that randomly stopped working a few years ago. I tried many things at the time, and intermittently tried to fix it over and over again.
Currently it turns on to the blue light, screens are always black.

The worst is when its a dry poop, then you spend 20 minutes and ha!f a roll of TP wiping. Its like wiping TP over a magic marker, just won't stop showing.
