Nintendo 3DS

Problem

Solution

Console turns off after 2-3 Seconds with a Popping Sound

The three main causes (credit: MilaNavi on YT) for any device in the Nintendo DS/3DS family to turn off with a popping sound are faulty ribbon cables and/or connectors for: the upper-screen 3D (these are actually two cables); the lower LCD backlight; the speakers. Reseating one or all four of these cables might fix the problem. If it doesn't, the cables themselves or the connectors will probably need to be replaced.
