    Not sure,
    But I've pointed you to two parts that is related to the 3ds' power issues.
    Albeit, most probably the fuses are ok, but those parts aren't, probably due to bad board design making other parts break first due to power failure instead of the fuses itself

    Do you know where I can find a replacement charge ic for the new 3ds xl? I made the same mistake of placing the battery backwards. I have replaced the daughterboard and it finally turns on but it doesn't charge even when the orange light comes on. Sometimes when I unplug the charger, the orange light stays on.

    I found a similar chip on my old 3ds xl that says:

    CKP
    TI 281 <-------- I'm not sure if that was a 1.
    C3GG

    So, do you think this would work if I could transfer this chip to my new 3ds xl?

    I'm really not sure, the pinout maybe different and you could end up ruining the board more,

    are you looking at this very part?
    can you post a clearer pic? (please see reference pic) thanls

    that could be an "I"
    since the first chip's last character is a Letter

    my CKP search seem to say that
    CKP is related to "power smd's"
    Code:

    TI could be "TEXAS INSTRUMENTS" which is know for semiconductors

    I searched for a good 10 minutes last time. I'm consulting my friends into hardware stuff

    So, I've replaced the power board. Now, when I try to start the console, it shows the blue light for about 3 seconds, then shuts off with a short "pop" sound. Neither display lights up, and there's no difference when I use the charger as well (other than the charger light). How do I fault-check this?

    Check your ribbons. They are not seated proper.

    That means the power ribbon for the display is not secure. The same thing happened to me so I put duct tape over it to hold it into place.

    Thanks!

    So, I've tried reseating all the ribbons, and the problem seems to persist - though now the red light lights up before the "pop", instead of the blue one. I guess I may have broken either the cables or the connectors, though if so it's not immediately apparent?

    Probably, take extra time when doing the top screen ribbon, that upside down one is truly a pain.

    The top screen ribbon is one of those two on the face-down side of the PCB?

    Found some stuff:
    Photo from the ifixit teardown of the n3ds xl: https://d3nevzfk7ii3be.cloudfront.net/igi/IKlW6WTZKKmapYkt.huge
    Texas instruments "USB-Friendly Li-Ion Battery Charger", part number bq24072 is said to be marked CKP: http://www.ti.com/lit/ds/slus810k/slus810k.pdf
    Available from Aliexpress for about $8 for 10x: https://www.aliexpress.com/item/Fre...TR-BQ24072-BQ24072RGT-YF1122/32544876943.html

    Dunno if I've found the right part though, maybe someone better informed could weigh in

    edit: found better price

    That is a great find, but shipping is like $40 to the U.S.
