    Hey guys!
    I got a customer N3DS that seems to be stuck in sleep mode.

    Let me explain the whole scenario:
    The customer bricked the console and sent it to another "technician" who screwed the board big time: ripped off the original CLK and did a whole mess with a connector.
    The connector is the one that the small flat cable coming from the bottom screen goes.

    I swapped this connector, re-flashed the NAND (yes, the console had 6 different copies of it) but when I power the console on the blue LED and after a couple of seconds the yellow LED lights. A few seconds later the blue LED dims and the yellow starts blinking.

    I tried all 6 NANDs (NAND x2, sysNAND x1, emuNAND x2, formatted x1), all with the same behaviour.

    I wonder if the connector related to the small flat controls the sleep state. If so, I just need to rework it.

    Any advise is welcome!

    Thanks!

    PS: Little video showing the issue!

    This sounds like an MCU brick and will likely be unfixable.

    @vb_encryption_vb might offer some advice, but I think it's toast.

    Thx for the commend, mate, but I think this is something else.
    It doesn't look like a brick. A brick would be no yellow light (wifi) and a solid blue light.

    The customer had it bricked but he also had working NANDs.
    I re-flashed them and the behaviour after each one of them is consistent with a console is sleep mode: blue led slowly dimming and lighting stronger, in a cyclic way, and the yellow light blinking like crazy (you know when your 3ds is downloading a new software version is sleep mode?? like that!).

    The console enters in sleep mode when the speaker magnet approaches a detector in the bottom lid. Maybe that's broken. Try putting a magnet in the other side of the console.

    Try removing the battery for a few seconds, replace it. Then boot again.

    I'm gonna leave it like that while I try replacing the button board, since the sensor is there (following @PabloMK7's tip)

    You'd never guess what the issue was... so lame! so dummy! :(
    It was dirt inside the power flat connector... yeah! A drop of isopropyl alcohol solved it :(
    Thx guys for your tips! Specially @PabloMK7 for the tip where the sleep sensor was!

    Cheers!
