Hardware New 3DS XL- No power,no charging

Skrypciak · May 31, 2020

So, i was changing the abyx buttons i got too excited and i've put my battery in backwards. The 3ds didn't want to power on, so i tried charging it. The orange light came on, and after i unplugged the 3ds and plugged it back in again it did not want to charge.

I've started reading and came up with the conclusion that i broke the power/abyx board, and possibly the charging ic.
So, is my conclusion correct or did i miss something?

(Also sorry for my bad english, i'm still learning)

Thanks for any help.

You could have blown a fuse somewhere
The charging light doesn't turn on at all anymore, not even for a few seconds?

No, not at all

I tried a new battery, it now pops which (assuming that im correct) is probably a short somewhere.
Also, i'm sorry for any late replies.

Pops instantly when you turn it on or the blue light goes on for a second and then it shuts off with a pop? If it's the second thing it means that not all important parts are properly connected
If it pops instantly then yes it is probably a short somewhere (probably from the charging/battery IC)

It stays on for 2 seconds or so and pops. Do i need to reconnect everything or specific components?

You should be fine with just the screens and speakers but I'm not sure about the new 3DS XL

I probably found the culprit, the cable in the photo is delaminated(the cable splits near the connector)

Try removing that cable and see if anything it changes, it doesn't look like one that's required for the system to boot

Didn't help, i will try reconnecting the other ones
Edit: Tried all the connectors on the top of the board, as i only removed the abyx board. But i heard something loose in there im going to take it apart more and see what is loose

Took it apart, reconnected everything. Still pops after a couple of seconds.

Do any of the screens flash white?

They don't, also tried booting into gm9 the console just turns off.
Edit: Can a small dent in the cable affect the 3ds? It looks like i messed up during my first disassembly, and there is a dent in one of the cables

Yeah it's possible that it broke the cable, can you send a picture of that?

The image is too big so I uploaded it somewhere else

Yes that cable doesn't look very good, it could be causing an issue
Sorry for the late response

No problem. What is that cable for by the way?

Top screen or bottom screen signal, I can't really be sure from that picture and I never had or opened this 3DS model

It's probably the bottom screen flex. Thank you so much for the help
