Hardware Fixing New 3DS XL black screen by unplugging camera question?

[jon909]

Hey guys, I was successful unplugging the camera to fix the black screen on my first New 3DS Xl, but now I am trying to fix another.

I removed the camera cable again, however I noticed this time there was an additional ribbon cable underneath the camera ribbon cable, they are kinda attached to one other.

Are both ribbon cables supposed to be unplugged?? I am not sure when I was successful with my first try if I just unplugged only the top cable or both.
With both cables unplugged my 3DS does not even turn on and play sound anymore, just turns on and off right after.

I am supposed to plug the bottom ribbon cable back in? How do I put it back it in? Its smaller than the top cable, so where exactly does it go?

I thought since I fixed one already this one would be just as easy.

Is the 2nd 3DS you're fixing also a New 3DS XL? The camera ribbon cable is found at the top right corner when flipped from the back. See picture.

The camera ribbon cable is the fat black one on, the front and back cameras are a 3 camera assembly.

There are 3 ribbon cables in the top assembly:
1. screen
2. speakers, volume and 3D controls
3. camera

Depends on which one you unplugged.

LCD and the controls are on the other side of the board from the cameras.
