    If you are sure it has never been modded, then it may be a hardware problem.

    Most probable cause is linked to the speakers flex cable (either connection or state) especially if you hear a small pop noise before it switches off. Check in this order:
    • Disconnected cable (easy - just reconnect)
    • Corroded contact on the ribbon cable (easy - sand & cleanup with IPA )
    • Corroded contact on the board connector (medium - use toothbrush to clean slowly with IPA, use a pick to clean contact, very carefully)
    • Broken cable, either fully or partially (hard - buy and replace connector, tutorials exist | very hard - remove and micro solder traces before reinstalling)
    For the last case, you'll need to disassemble the top screen completely, which is very tricky, and comes with a risk of additional damage. Here is the disassembly guide:

    Unfortunately, the speakers flex cable is located beneath the motherboard on the n3DS XL, which will force you to disassemble a lot before testing.... For the old 3DS XL, it was located on top, so you just needed to remove the cover to have access.

    By the way, all 3DS are very touchy about not having some components working. Some are not needed, but others are... You don't need the joystick, or the cameras to boot for example. But you'll need the speakers, the top screen (at least partially), the daughter board...
