After re-assembling my 3DS XL, we booted up the system to see the bottom screen turn on and the touchscreen function but got no display for the top screen. With some digging, we concluded it was the top screen LCD ribbon connector and went back to reconnect it. Indeed, the connector was crooked and we fixed it soundly.

Upon our second re-assembly, we can no longer get either screen to display anything. I have tried a great number of things, such as:

Making sure the wifi card is connected

Reseating the bottom LCD ribbon connector (I'm not sure if this is in all the way.)

Reseating the thinner ribbon connector next to the bottom LCD ribbon connector (The clasp on this connector was broken. However, it stays in like a champ and I'm confident this is not the problem)

Any help would be greatly appreciated! I can provide pictures of whatever is needed.

How do I fix it? I’m willing to crack open the 3DS as my final goal is to completely fix it and keep it. :)

Thanks in Advance

I replaced the button sticker of the console due to a problem I had with the buttons and that went perfectly. However, in the process, I teared the camera flex cable a bit and now the back camera doesn't work, it stays on black, doesn't freeze the console.

I guess due to a health problem I have for some time my head isn't where it has to be since it's the first time I tear a flex cable

Replacing the cameras is a bit more difficult, althought for me the most difficult part would be being able to put the screen back without any dust particle inside. Which has been always a pain for me. Is there any other way?

Hi,

After reformatting my SD card one time, I needed to setup my 3DS once again. I chose my language and then had to move the 3D slider to the right of my screen all the way up and click next. I did that, but when I click next, my 3DS still tells me that my 3D slider is not fully turned up. My 3DS is far over warranty and I really don't have the money currently to send it into repairs, I just want to play Pokemon, you know? If you have any suggestions I would love to hear them and would appreciate them greatly. Thank You!

I guess Nintendo made some kind of modification to the mainboard. Maybe a jumper, maybe a chip that needs to be replaced, I have no clue.

I know that there are people out there with the same problem and I would really appreciate if someone knows how to fix it.

bought this 2nd hand 3DS in very good condition, however...

the screen is dim = dark when looked at straight. When I view from an angle I can see the (expected) screen content, so it seems the screen is somewhat working...

Does this mean the back light is broken?

Can it be fixed without exchanging the whole screen, e.g. re-seating cable or other "trick"?

If not can the back light be exchanged separately or only with the screen itself as a whole assembly?

Thanks and have a nice day, Mike

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 ;-;
