Hello guys! I just disassembled a bricked New 3ds XL that I just bought to change its motherboard. After reassembling it, powered it on and voila! It was working, although the top screen was black. I thought I may have had some ribbon unplugged, so I just started all over. After reassembling it for the 2nd, 3rd and 4th time, the top screen works flawlessly but the bottom screen doesn’t. Im kinda new to this, so I don’t really now which exact ribbon is the one that powers the bottom screen, and I don’t want to disassemble it many more times to avoid damaging the new board, Could you give me a hand? <3
