Hi, I have just replaced my 3DS XL hinge and case. Therefore, I have taken out the motherboard and reassemble back. After that I am not able to turn it on again. There is no LED light up. But when I plugged it to the charger, there is the orange LED lighted up and the moment I pressed the power button, the blue LED lighted up for 3-4 seconds and disappear. There is no pop sound or any other indication. Hope to get a answer. Thank you for your time.
I have the same issue as yourself. I repaired my system as the top screen needed replacing. Put it back together, tried to turn it on but nothing happens. It will charge but when I press the power button the blue light flashes for a second then goes off. It’s like a blown fuse or short circuit or something is my guess…
