    Hi, guys... I've been reading posts on this site for some time now, but I finally registered and now I'm posting for myself this time. I'd like to thank everyone on this site for the endless knowledge that's shared. I'm an electronics guy by trade and I'm kind of stumped here because of my lack of 3DS experience (I fix avionics systems on planes, which I learned in the Marines and tinker with stuff all the time.). My buddy had a Zelda edition N3DS XL that was bricked. He gave it to me and purchased another N3DS XL. We ordered a new motherboard and power board for this broken console. I transferred the motherboard and power board from his replacement console into the Zelda edition one because I know he's a huge Zelda fan and I didn't like the idea of fixing it and he no longer having it. So, I got it working and gave it back to him. The motherboard and power board replacements came in and I installed them into the broken console I was left with after the organ transplant. lol After cleaning out the ribbon cables with alcohol and swabs, I got it to turn on after a few tries, but only with power applied. The joystick isn't working now, but that's no biggie to replace, nor should it affect boot up, I'd think. It booted up completely and I'm able to navigate without a problem after the first 10 seconds that it goes haywire due to the joystick not being recognized. The cartridge reader works as does everything else. It doesn't boot up on battery power, only with the AC adapter connected. I removed the battery and attempted to turn it on with only the power applied, but it didn't start up. I assume it's recognizing the battery because it didn't boot up without it using only the power adapter. I used another battery that's a known good without power applied and the second battery didn't boot it up either. It appears to be charging, but I don't know for sure as I haven't left it long enough to do so as I don't want to burn something out. Anyone have any thoughts or suggestions as to what I can try out to get this console booted with only the battery?

    Sorry for the long post. I just figured that I'd explain in full to paint a picture, so to speak. lol
    Thanks in advance for any thoughts or ideas that you may have.

    Why do you need to replace the power board for a bricked 3ds? Just need to replace the motherboard...

    The motherboard was bricked and should've been the only swap, yes, but for some reason the power board went out as well. I swapped out the power board with the known good one to come to that conclusion before I ordered the replacement. No clue how or why that happened, but it did. Since my buddy isn't of the technical sort, he really didn't give me any explanation so I can try to come up with a reason as to what may have happened. lol

    Huh. That doesn't sound very good. I can't even think of a reason why that would/could happen other than the wiring for the battery compartment is fudged somewhere.
    Sounds like it sees the battery, but can't pull any juice from it.

    Sounds like your spare parts are from a demo unit...

    Yup, the replacement parts may be from a kiosk unit (which is in stores and only works when plugged in to a power source)
