Hardware Tried to fix faulty B button on New 3DS KTR003 and now the system will shut down shortly with a pop

Deleted member 557207 · Apr 15, 2021

B button had some mess in it that prevented it from pressing down. I cleaned that out and it presses fine now, but now the entire system powers on but then shuts off quickly afterward with a pop. I only touched the sd card cable, the 3 orange cables that connect to the motherboard and face button board, and the ribbon connecting the c stick to the face button board. Additionally, the white latch that connects the ribbon cable from the face button board to the motherboard snapped off but I was able to secure the ribbon cable connection in with some electrical tape. I took everything apart and put it back together multiple times to see if it was just a loose connection but nothing has changed.

My system is hacked FYI and I know that the sd card connection is being acknowledged because the shut-off and pop takes longer to happen whenever I have the sd card plugged in. This happened whenever the machine was working as well.

It's very likely that it's not actually making a connection, you should try reattaching the white latch instead of trying to tape the cable down and hope that it will work.

I fiddled around some more and found out the way I applied the tape was making the ribbon cable come out of the mobo socket whenever I put it all together. I found this out a little late because I also proceeded to blow a fuse on my button board putting the battery on the button board connections without reassembling the entire thing (was troubleshooting and I didn't want to put the entire thing back together each time. The multimeter showed no continuity so I'll have to get a new button board on amazon. Thanks for the advice though man.
