回答“Why won't my Nintendo 2DS power on?”Had this happen to my son's 2DS today, and I was able to fix it. For clarity's sake, my issue was this: no matter if the 2DS was connected to the AC adapter or not, when the power button was pressed, the blue LED would light for a couple of seconds and then extinguish. If you listened closely, you could hear the speaker "pop" when the LED turned off. How did I fix it? Follow along: (1) Remove the battery cover, battery; (2) Remove the back case, and gently release the rear camera ribbon cable from the mother board. (3) On the motherboard, there are two other ribbon cables (near center). For some reason, my research landed on many people that said if the contacts on these cables get misaligned (through dropping, whatnot), it will cause the LED activity that I mentioned above. (4) Release these two cables, then re-insert, and ensure that each cable is in completely (and straight) before clamping down again. (5) Connect the battery, and test your DS.
