3DS / 3DS XL top screen ribbon cable damage (shuts off when opened wide, top screen blank or flickering)
The cables from the top half of a 3DS pass through the hinge and can tear or work loose after years of opening and closing, or after a drop. Typical signs are the console switching off when the lid is opened past a certain angle, or a blank or flickering top screen. Because the top-screen cable is attached to the screen, the usual fix is a new top screen assembly, threaded carefully through the hinge.

3DS blue power light flashes then switches off (often with a pop from the speakers)
A 3DS-family console that flashes its blue power light for a second or so and then shuts off - often with a pop from the speakers - usually has a ribbon cable that is torn, unlatched or not fully seated, or a poor battery connection. It is especially common straight after a screen or hinge repair. Check the battery and charger, then reseat and inspect every flex cable before looking at fuses and diodes.
