So I've recently been tasked with trying to fix a friends kids two broken 3DS' "His kids broke TWO 3DS'?!" trust me I know. xD
Anyway I've cracked both of them open and found the one has a broken pin in the cartridge slot fine that's easy enough. The other however I feel may have some motherboard damage in one of the top screen ribbon inputs. I've tried both tops screens in this motherboard and got nothin' on the top screen. Is there, I dunno, a way to tell if the slot on the motherboard is broken? It looks fine as far as I can tell.
