My son broke the hinge on my wifes’ 3ds xl so I ordered another hinge plate and went about fixing it. Now ideally I do not work on handhelds due to cramped work areas. Big hands and fat fingers make the process a nightmare. Hinge replacement became a top screen replacement when I accidentally tore the ribbon cable trying to get it back through the barrel hinge.
So while putting the new screen in it and getting it back together it refuses to turn on. Blue light kicks on for a second then right back off. It does not have CFW, it’s stock. I also broke one of the ground wires to a speaker. I did solder it back on but the job isn’t great. What could be causing the issue. Speaker, or maybe loose connection to the board?
