Well after doing some digging all I was able to turn up was that some people claimed to have tripped over the cord while charging and it either bent the pins in the charging port or it broke a solder connection between the motherboard and the charging port. Checked for bent pins and very carefully examined the connections on the motherboard and just for the obvious I checked the connections in the battery compartment. All connections are being made and nothing seems bent or broken (I compared the port pins with a friend's) and even tried a different charger. It works just fine while on the charger and Ive been able to play atleast 10 hours of uninterrupted gameplay before just saying that it works good and setting it down, but I know it's got to be bad to just leave the thing on the charger so I only plug it up when I want to play.

I have updated and reformatted the memory and have even fully charged the battery and let it die over 20x. It appears to stop charging after about 20 minutes then you can turn it on and it will work for approximately 10 minutes before going dead now. Some improvement but nothing praise worthy.

Anyone out there have any ideas that they have in mind that I could check/verify or try to fix? I would ship it off to Nintendo but they are charging 85 for me to mail it and I only paid about 30 bucks for the thing. Like I said though everything works great it just wont hold a charge. It also didn't appear to have suffered water damage.

Thank you for your time and hopefully one of the IFixit gurus out there will see this and know what Is up. I'm gonna run it up to CPR tomorrow just for giggles to see what they think but I don't want to commit to anything until all my options are considered. Because most places are gonna charge me 80 bucks for 10 minutes of labor and a 2 pin resistor.

I have a soldering iron and decent soldering experience, but it'd still be nice to know if it even COULD be repaired before I try.

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. :)

Are there any other reasons the system wont charge/the charging light wont appear? Any fixes?

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
