I've been trying to repair my old 3DS, and for the most part this has gone smoothly with minimal issues. The only problem I'm facing immediately is that I'll need to do some soldering to re-affix the charging port. I have zero experience with this and need a hand identifying what steps I should take with my console.

I've tried to get some up-close photos of it, and I can see a little bit of green/yellow missing from the outer soldered point. They appear black up close, and with some further inspection also seemed to have a residue of something, very thin and eggshell-like.

I'm looking at all sorts of guides to try and figure out what to do, but I've yet to come across any that have damage even remotely similar to that on mine. The port itself doesn't look damaged, thankfully, I'm just struggling to tell where to start on fixing it.

I cleaned it up using a toothbrush and 99% IPA.

Even after the clean, it produced the same results of claiming to be charging but never actually turning on or showing the blue LED.

I checked for shorts, couldn't find any. I also check F1 and F2 fuses which both showed to be fine.

I know there was a lot of corrosion but I just don't know what the problem could be. If you have any advice, please let me know

How do I reattach a ZIF latch with this odd port? Do I have to take the ports off and solder new ones on? I want to get my 3DS up and running again.

Here’s the images of the ‘damage’

Also, here’s how the latch should normally look while it’s on.

i replace the battery by searching the model number on amazon and buying a new one.

it's early 2026, and i have used this battery for 3yrs at most - i dont know why it's expanding already? i noticed the back plate was bulging a tiny bit, and opened her up to take it out asap to avoid any issues.

could there be another hardware issue leading to this happening again? should i just try and find a refurbisher? i dont really want to leave my device in someone elses hands if i can avoid it, she's important to me.

any advice is appreciated, thank you in advance !!!

• Issue is the same with another battery and current battery work fine with another 3DS
• Without the battery, orange light turn on for 5 seconds as expected
• When turning on, charger is recognized and orange light turn on normally. Charging logo appear on the top screen
• But when the console is closed, sleep mode, orange light still turned on
• When the console is turned off, orange light is on for 5 seconds before turn off. Plug again charger doesn"t make the light appear unless I remove and replug the battery, no matter if the charger is removed or still plugged
• At the beggining of the issue, when turned off, orange light stayed on indefinitely even with unplugged charger
• The console has never contacted water

Here's some pictures if it can help. Thanks you for your time

I over-charged her across a few months and needed to replace the battery because of it expanding. However, now she seems a bit slower/fried, game cards not loading in sometimes, boot-up taking several seconds etc.

I've recently seen videos with replacing the charger port with usb-c, replacing the bottom screen for a glass one etc.

I basically want to know what things i should look into replacing and upgrading to help her run more smoothly and last longer!

I'm happy to answer further questions and resources for further reading on 3DS modding is appreciated as I'm also unsure of what I should be searching for.

Thanks for your time!!

I have a 3DS XL that I cleaned because it was water damaged (nothing burnt on the motherboard so should be fine). It turned on before cleaning, but after reassembly, it turns on and off with the blue led turning on and off too.

I've seen that some people could hear a popping sound, which isn't my case.

I found one of my ribbon cables, with some sort of a black coating around, to have a little scratch and I was wondering if it was the problem.

Can someone help me please ?

Thanks,

My name is Neto and I've been having a problem with my Nintendo 3DS for a few months now.

Some time ago I ran out of 3DS chargers, so I put off buying another one, but after a month I finally bought one. When I plugged it into my 3DS to charge, I left it charging for a long time, and then when I turned it on, it wouldn't turn on at all. The orange charging LED appears, but when I press the power button, it doesn't turn on. After a while I tried again, but now another situation has occurred. The console would turn on, the orange LED would light up, and after a while the LED would disappear. I had to unplug the charger and plug it back in to turn it on, but it always disappeared. Note: I tried with another battery from a friend of mine that was working normally, but without success.

I would appreciate any help.

i managed to follow the guide completely, succesfully replace the screen and happy days it turns on and plays games perfectly, the 3D also does everything it needs.

So when I have the DS in playing position (top screen locked in) its perfectly fine for hours of gameplay, if I overextend the screen or put it in the 90degree angle it turns black. when I pop it back in playing position its on again. Is this a normal reaction or have I missed something on the assembly? You would think it would happen 1 way as you overextend or close pulls the cables in different ways?

Is it worth opening up again and what should I look for if it is an issue?

because I have the same USB-C replacement kit from Aliexpress has this video but when I was removing the broken charger port I ripped off the pads on the pcb which I had to solder to.

Then I thought maybe getting a physical copy of Smash Bros would do the trick. I uninstalled the Smash Bros game from my SD card and ordered a physical copy. Just got it in the mail today and put that in the cart slot to try and launch the game, but it did the same thing that booting the game from SD card did. I even tried powering off the 3DS, removing the SD card and game cart, powered it back on and reinserted the game cart and launched the game again, but still got that black screen.

No idea what to do here.

Recently I got a 3ds - The small first version.

When I plugged it into the charger, I noticed the light turn on, but when I try to turn the device on - nothing!

The lights turn off when I press the power buttom and after a few secounds - turn on again without the decive coming to life.

theres no crack on the screen.

Thanks you.

Specifically, when I use each single eye to look the top parallax screen, only my right eye could see clear image, but my left eye see very dark image which is hard to figure out.

So what do you think the issue is that happened for the 3DS parallax screen?

I dropped my new Nintendo 3ds XL (purple galaxy one) one day and when I went to turn it on, it stayed on the black/blue screen that appears when the console it loading. At first, it appeared to be a soft brick which was supposed to be an easy fix: everywhere I went said to put a combo of buttons in and press reset, which i did, but nothing seems to be fixing it??

If I hold down the power button, it’ll send me to the power off screen and the bottom touch screen still works. When I press the home menu, it gets stuck loading the home menu forever. I really have no idea what I managed to do to this thing. I even bought a screwdriver to open it up and see if it was because of the WiFi chip, then found out it’s on the TOP portion of my 3ds and got too scared to take it apart again lol. I have it backed up on my computer, so I won’t lose anything, I’m just like. Completely out of ideas. I genuinely have no idea what’s wrong. My only guess is I managed to corrupt the home menu???? Which is like…how??

Any advice is appreciated, as I have tried all of these things and nothing is fixing it:

-booted into safe mode, reset and nothing happened.

-reset the home menu with a button combo, nothing happened

-waited on the soft brick (nothing lol)

-opened it to see if it was bc the WiFi chip was loose, (found out it was on the top screen, THEN found out the newer model has the WiFi chip on a motherboard so idk how that could’ve gotten loose), I am willing to try it again if someone can show me a guide for the specific 3ds I have (I’m getting a little desperate LMAO)

The only thing I haven’t done is brought it in somewhere, I am trying to find a solution without spending money but I am afraid it’s coming to that. Again, any advice is greatly appreciated. Thank you for reading this long winded post, I miss my tomodachi life game. It’s just like, it literally works I watch it work then it just gets stuck infinitely loading nothing.

Do I even need this part and do I solder it or something.
