I took apart the system to replace the XYBA button contacts and then after putting it back together the system had an issue with turning on and then turning off with a pop. I have since fixed that problem by replugging some cables however now the system blue light turns on while nothing else does. If i charge the system the orange light will turn on but will immediately turn off upon turning the system on. If I remove the sd card the blue light turns off immediately instead

I think i found the problem

Update: I've wiggled the cable around a bit, and now left and right work, but up and down don't register at all.

I'm aware that if the blue light flashes on then back off again, it has something to do with ribbon cable issues, which I'm more than aware of. But I have a few concerns: namely, which cable?

The most pressing issue is that the cable connecting the joystick to the main board isn't seated properly. I ordered a few replacements so hopefully the little plastic latch letting the joystick cable seat into the mobo will fix my problems, but I've also tried the bathtub moonshine solution of electrical tape over said cable and it still wouldn't boot: not surprising, it seemed to be misaligned each time I tried it.

One thing worries me though: this little black cable at the top. All the other ribbon cables and connectors appear to be intact, but because this was the first time fully breaking down a N3DSXL, I fear I may have roughed this (particularly delicate) cable up too much and will need to replace it. Can anyone confirm or deny my concerns so I know what to replace if the plastic latch doesn't fix the issue? Every other ribbon cable seems to be in good condition and seated properly.

I believe i broke a locking ribbon cable on my upper 3ds xl screen. Specifically the annoying one of three in the top right corner and now i cant get it to lock down. I used UV glue in the meantime but now my 3ds intermittently turns off every once in awhile. How can i fix this without buying a whole new 3ds?

! I hope someone might be able to help me out here.

I was doing a capture card mod on my New3DSLL (the japan version of XL) a year or so ago now and when I got to the step on making sure everything still worked, well it didn’t work. With the battery connected I get no reactions from the device when trying to power it on. No amber, no blue, no lights at all. If I plug it in without thr battery the amber light lights up for 5seconds then goes off. If I connect the battery and the charge it lights up amber but still does not turn on.

I believe I may have accidentally put the battery in in reverse when I was trying to test ot initially, but cannot be too certain that that was the case.

I tested the red (0.012) and the blue ( 0L and then 12.00) as labeled on that one picture that floats around from infinity (it wont let me add the picture sorry). I am not too knowledgeable with multimeters and dont know if this is right.

Does this sound like a case of one of the fuses or the chip on the daughter board for the abxy being blown or does it sound like something else is wrong along the way of doing the mod?

Thank you in advance <3

i don't know about how many games i have on it becasue of the 300 games limit i read about and even tried deleting some i didn't play anymore, coud anyone help me with a step by step guide? i am not very experienced with these kind of things.

So I figured the battery must be dead. So I order a new battery, and when it arrives I make the replacement and let it charge. Same thing happens, the power light turns red a couple of times.

I grab my brother's 3DS and put the battery inside and find that the battery works and is fully charged (Meaning my 3DS is charging the battery, it's just not displaying the orange charge light), I swap back and decide to take it to a local game store.

The local game store refuses to do anything with it, but tells me there are signs of internal corrosion. They tell me a place to call, but the place I called says they don't do systems as old as a 3DS.

So now I'm stuck wondering, what should I do? Does anyone have any ideas what could have caused this and if it's fixable? Thank you, this 3DS has a great deal of emotional value to me, and there are a few miis I want to try grabbing off of it.

Also I've tried multiple apps to reset them in cases of them being broken or something like that and also they're not counterfeit

⟐ Commented April 17, 2026 at 10:44 MST

Help is very much needed as i do not know how to diagnose or fix my dear 3DS without guidance.

Thank you!

When reassembled, the system now feels a little loose and makes a creaking noise when holding it, since it's unable to be fully screwed back in. Broken screw is shown on the right, left is still intact.

⟐ Answer accepted March 21, 2026 at 15:34 MST

I tried different games cleaning the games and any software issues that I thought of.

The only two things I can think of is the tiny bit of of blue green corrosion by where the game card connects to the motherboard.

The sd card also is not reading. Please help

Yes I do have pictures sorry if quality is bad
