    All right, hear me out everyone! I've been through a blown fuse before, and I know for a fact that this isn't it. I was performing a hardmod onto my friend's Mario/Luigi 3DS and I did it successfully (I love soldering onto systems, I've done mine so many times.) The system turned on fine, but wasn't being read. However, that isn't the problem. The problem is that after a while, I didn't touch the system for a few days after having removed the hardmod (I tested the system's power after removing the hardmod and then left it alone.) When I turned it back on, blue LED and a pop and it shuts down. Okay, let's try out a different motherboard from a different Pikachu O3DS. Test motherboard on other system and it turns on fine. Switch motherboard and same problem. Tried both boards on the Pikachu 3DS and they turned on fine. Any help?

    tl;dr, motherboards don't seem to work when tested in one 3ds body but turn on fine with other 3ds body

    Did you check to see if you accidentally soldered two pins together or something? It sounds like either a blown fuse or a short somewhere in the system.

    Are you sure you got all the zifs seated correctly because if you don't put the backlight in correctly this happens

    To the two people who said it's a blown fuse, it's not. It powers on properly when I put it into the body of the Pikachu 3DS, but not when I put it into the body of the Mario/Luigi 3DS.

    @Thee_BaBs I've double-checked every single connection in the 3DS, but will check again.

    probably your lcd flex not making good contact on the board.
    I know you said if you switch boards they work just fine. still depends on how good the contacts are.

    IIRC the pop sound comes from either the screen or camera's ribbon cable not being connected correctly. (Or both)

    Sounds like a cable issue, I had something like this before, and fixed it by reconnecting all the ribbon cables.
