I would like to fix this myself if possible. I lent a blue O3DS unit to a friend for a long time. I got it back and it won't turn on. When I turn it on, the blue power led lights up and the bottom screen comes on for about 1 tenth of a second before the system shuts off with a *pop* sound. Can anyone tell me what might be causing this? They had it for a while so anything is possible. Also, the warranty has expired and it is on a <9.2 firmware so I would avoid shipping to Nintendo. Any help is appreciated, thanks!
