Nintendo 3DS XL 2015: My system will not turn on, I've tried replacing the battery

Sat, 18 Apr 2026 02:56:08 -0700

I recently got my 3DS out of storage and found it wouldn't charge or turn on. If I tried turning it on it would flash red a couple of times on the power light.

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.

Game Boy: red light, sound but White/Black screen | led ok, son mais pas d'image

Fri, 17 Apr 2026 10:47:55 -0700

Hello,

I tried to fix my GB DMG but I could not. The problem is pretty simple, I have red light, sound, game starting (I can hear the music of the games) but nothing on the screen.
I know it's not coming from the screen board because I tried with two other screen board from two working gameboys and I have nothing on the screen when I try on this particular one.

My guess is that something is wrong on the other board (the one olding CPU, cardridge reader, power) but I could not find what.

I cleaned up everything with IPA and contact cleaner with no success.

I am running out of ideas so I'm posting here in case someone can help me.

Bonjour,

J'ai essayé de réparer ma Game Boy DMG, mais sans succès. Le problème est assez simple : le voyant rouge est allumé, le son fonctionne, le jeu se lance (j'entends la musique), mais rien ne s'affiche à l'écran.

Je sais que le problème ne vient pas de la carte écran, car j'ai essayé avec deux autres cartes écran provenant de deux Game Boy fonctionnelles et le même problème se produit.

Je suppose qu'il y a un problème sur l'autre carte (celle qui gère le processeur, le lecteur de cartouches et l'alimentation), mais je n'arrive pas à trouver laquelle.

J'ai tout nettoyé avec de l'alcool isopropylique et un nettoyant pour contacts, sans résultat.

Je suis à court d'idées, alors je poste ici au cas où quelqu'un pourrait m'aider.

New Nintendo 2DS XL: Nintendo New 2DS XL does not power on after battery replacemet

Fri, 17 Apr 2026 06:44:44 -0700

Hello,

I recently purchased a new battery for my Nintendo New 2DS XL from iFixit. The device was working perfectly before the replacement. I decided to replace the battery because I have been using the console since launch day.

After installing the new battery, the 2DS no longer powers on. When the charger is not connected, no LEDs light up at all. When I connect the charger, the battery LED lights up orange. If I then try to turn the device on, the power LED turns on for about less then one second and immediately turns off again.

I have also reinstalled the original battery, but the same symptoms occur now.

Any help or guidance would be greatly appreciated.

Kind regards,⏎

Nintendo Switch: Can anyone help me identify where this pad lead to?

Thu, 16 Apr 2026 05:30:38 -0700

I tried (& obviously failed) to swap the display flex ZIF socket in the original first-gen Nintendo switch and tore a solder pad off. I’m pretty confident that I can fly a wire out from that remaining bit of solder pad, but I need to check whether I did the job properly. Can anyone tell me where this particular pad(10th from the left not counting the large one) lead to so I can check it with a multimeter or smth?

Thanks in advance!

Nintendo Switch: No output to TV on Nintendo dock. But ok on third party dock.

Thu, 16 Apr 2026 00:12:00 -0700

My Nintendo switch (non OLED) all of the sudden stopped showing on my TV. It charges on the dock and the Switch screen goes black when docked. The dock little light also goes green.

Tried numerous things:

Checked HDMI.

Plugged power source directly to the wall.

Followed the correct way to connect the dock.

Tried different TVs.

Finally decided to buy another dock and got a third party option from AliExpress. It works fine. However I was not happy with it because the USB-C connection is a lot tighter compared to the Nintendo dock. So I decided to buy the Nintendo dock that comes with the OLED version (has a LAN port).

To my surprise it has the same issue as my original Nintendo Dock... No output 🫠.

Has anyone had a similar issue?

Nintendo Switch: My iFixit battery for my Switch is draining quickly - why?

Wed, 15 Apr 2026 22:30:59 -0700

I have a Nintendo Switch, from about 2020. This is the model with the detachable joycons so I can put it in the cradle and see it on TV. I just replaced the battery last night with the new one I bought from iFixit. After completing that, I turned it on to be sure everything was working, then off. I was in my shop, so I left it off - I thought I had powered it down, but I guess not. 3 hours later I took it up to the house to plug it in and give it that first full charge. It showed 1% charge at that point!

I've charged it for over 6 hours and the next morning I left it in sleep mode, but pulled out the charge cord. Just sitting there, not used, in sleep mode, it's going through about 8-10% of the charge per hour! After about 4 hours, it's down to 62%!

Again, it is just sitting there, asleep, but not plugged in and it's draining that quickly.

Is this normal? I read that I needed to charge it up, then play and use it until the battery was low, then charge it again. I thought i had powered it down - guess not, so that's why it was in sleep mode after I put the new battery in, but today, after a full charge, and just sitting in sleep mode for ±4 hours, for it to be at only 60% does not seem right for a new battery.

Nintendo 3DS XL: What other things I should try to fix my bottom screen for old 3ds xl?

Tue, 14 Apr 2026 02:09:59 -0700

My bottom screen does not put out display, just all black but the whole device turns on and everything works, just not the bottom screen.

I know the motherboard is the problem and not the ribbon cable of my bottom screen as I have tested the screen on a known working 3ds xl board and it is completely fine.

Now I'm stuck with what to look out for to repair. The 2 ZIF looks normal to me as far as my eyes can see, I do not have access to a microscope to look a little closer.

So before I do anything, what other things I should look out for other than the ribbon cables? Is it possible that a fuse is dead and which one are those? Thanks for the help

Nintendo Switch: Loose LCD connector ribbon?

Tue, 14 Apr 2026 02:08:11 -0700

I had been using it normally, until these very fine vertical black lines appeared all over the screen. The colors of the pixels would then start to 'bleed' out, forming these bright horizontal bands. I've hopped between a few forums, and apparently a few others have had similar issues. Commenters said that it was a potentially loose LCD connector ribbon cable, so:

I'd like to know if this is the case for my device, and if so, how exactly should I fix it. Would disconnecting and reconnecting the ribbons suffice?
If it isn't just a mere loose cable, could it possibly be an issue with the LCD itself? If so, would it be better for me to take it to a repair shop?

Nintendo Switch: Lines on screen with "clear circle" in middle after LCD replacement

Tue, 14 Apr 2026 02:03:18 -0700

I am experiencing persistent display issues on my Nintendo Switch. There are lines running through the screen, and interestingly, there is a circular area in the middle that seems less affected by the lines.

I have already replaced both the LCD and the digitizer, but the problem persists. The symptoms are slightly different with the new screen: the lines appear whenever a new page or image loads, but if I leave the console on a static screen for a few minutes, the lines mostly fade away. As soon as the image changes, they return immediately.

I have checked and reseated the LCD ribbon cable multiple times. Is this likely a faulty replacement part, or could this be a motherboard/GPU issue (like a failing display IC or capacitor)? Any advice on what to check next would be greatly appreciated.

Nintendo Switch: Will the switch boot without an LCD

Tue, 14 Apr 2026 02:01:34 -0700

I bought a Switch v2 that has no LCD installed whatsoever, i checked for shorts or damage and found none. Then charged the console up to 4V and tried powering it up.

I expected some sound effect while it booted, but nothing ever happened. The speakers "hum" slightly for 10 seconds after i press the power button and then stop.

I do not have a docking station or any sort of usb c adapter to try plugging HDMI through.

So my question is if a switch can even be powered up fully with no LCD connected? AI chatbots claim it should power up normally.

I've opened the console up and cleaned the sd card slot pins with isopropyl alcohol and tried to make sure the pins were okay but the issue still persists

Also used some compressed air to maybe remove dirt from inside the card reader I've already ordered a sd card reader for the console but im wondering what other options i have,any ideas?

Nintendo DSi: DSI flashing light, turns off when attempted to turn on

Mon, 13 Apr 2026 10:51:06 -0700

So I recently bought a new touchscreen and shoulder Button cable for my DSI and I didn't get to test them cause it wouldnt turn on. I figured I put the battery in backwards and I checked the fuses and the fuse on the button board seemed to be dead. So I ordered a replacement that just came. I installed it, the fuse looked good, and it still did the same thing. I have two batteries and they don't seem dead as the multimeter says one has ~3.8v and one has ~4.1 volts. I put it in a bunch for both, tried many things, took out and reattached screen and camera cords, and nothing seems to work. I need help with this please!!!

Very simply, the L and R buttons on my DSi don't work anymore. I tried going to Nintendo about the problem, but they said it'd cost at least $50 to repair...and my system is long past its warranty. Will I have to take apart my DS to fix it?
