When I power on my old 3ds XL, I have a black screen error.
I can't use it at all
I already tried:
Shutting down and on, holding the buttons
Safe mode
Removing/ inserting SD card
Removing/inserting game
Replacing the wifi router
It's not modded, apparently it happened to my friend when she was playing pokemon (idk if it fell down)
Turn off wireless communications
I can solder and try to buy new components if needed
