These are the things I tested:

• Insert battery: turn it on —> nothing happen (no light)
• Remove battery, plug in charger: when plug in charger, charging led (yellow led) turns on for about 5 seconds then off. Turn on the device —> nothing happen (no light)
• Insert battery, plug in charger: when plug in charger, charging led (yellow led) turns on for about 5 seconds then off. Turn on the device —> device turns on and works as normal.

These are the things I found:

• Battery fuse was broken
• There is a short circuit as in the above picture

Please help me to fix it. Thank you!

I would like to add this occurred after the top screen was flickering for a few minutes. Then the system shut off, and when I restarted it the top screen has been dark as it is now. Restarts don't change anything.

Everything else functions perfectly normal.

So I followed the Upper LCD Replacement guide, I haven't finished it yet though but everything is taken apart. My question is, should I replace the screen still as depicted in the guide? Or shouldn't there just be some grime (because soda) I can wipe/scrape away? I am incredibly, incredibly poor. I'm making less than my rent right now, which is why I ask. 10$ even is very important.

I found some grime I scraped away on the ribbon on step 18, dunno what that ribbon does though. Could be more elsewhere.

Guide I followed: Nintendo 3DS XL 상단 LCD 디스플레이 교체

From this question: How do I fix my black top screen on a 3ds xl?

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.

I have 3 (three!) 3DS systems that have the same problem. When you press the power button, the blue light turns on for a second, and then the screen flashes with a popping sound and the system shuts off.

Any idea on what's going on here? I read something once about a fuse, but that was long ago.

Thanks,

Andrew

I was attempting to dissasemble the console for an upper LCD replacement when i noticed these strange marks on the ribbon cable in the hinge connecting to the 3D scroller thingie. Can I leave it as it is and have no problems or is the replacement of that cable necessary? If it is, where can I get these cables? Or should I just drop the repair and buy another 3DS...?

This is how it should be

And this how it looks when it gets yellow

And When it gets blue

I have tried changing the sd card ribbon cables

And seated the cables properly with double sided tape

any suggestions ?

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 was driving in a car playing my charged 3DS and then I closed it and set it down. When I came back to it, the screen was black, so I powered it off. It would not power on after I powered it off so I came home and plugged it in. I tried powering it on, and the blue light, the charging light, the 3D Slider light and the Wifi light were all on, but the screen was black. I tried unplugging it, taking out the battery, taking out the SD card and turning it on and off but none of those worked. I checked for water damage, by listening to see if there was a popping noise.

Finally after repeatedly pressing the power button, it went to the screen that comes up when you press the power button once (Not hold down) while the system is in use, where it prompts you to either power off or to return to home menu. From there, it was able to return to home menu, where it was stuck on the loading screen for home menu. (The one where it says Home Menu and has a white backround.) The sound plays when you press the home button, but it stays there forever, I've left it on that point forever and nothing changes. The result says the same whether I do it with or without the SD card. I can turn 3D mode on and have it work while on that screen and the power off screen.

I've been mostly careful with my device, dropped a few times, but I have a wrist strap that has prevented most falls. No water damage has ever happened. A X and Y buttons slightly cracked from excessive SSB4.

I am wondering if this is either something wrong with the 3DS software or if it is some kind of damage to the actual circuitry. Thanks in advance to all who help.

Edit I: 2 Minutes after posting this, I found something that seems to have worked.

I read on... 3ds xl powers on but won't boot

That if you hold <L> <R> <Up> (Not sure if it was D-Pad Up or Circle Pad Up so I did both) and <A> it could solve it. So I tried this and it is currently system updating.

Edit II: An Error Occurs while Updating? Can someone help me with this?

Edit III: 3DS was updated to latest version, but now I am back where I started ;-;

I cleaned the contacts and have continuity, but there are no signs of life. Zero sound, video, or light appear.
