Hacking Hardware Others New 3DS XL creates double/ghosting image

[S4NT11F0R3R0]

Hello. A while ago I bought a second-hand New Nintendo 3ds XL for €100 and I've always had problems with 3D. When I activate 3D, instead of generating the effect correctly, it duplicates the image. I have tried calibrating the 3d and super-stable 3d, but it still does not work correctly. I've also tried other New 3DS XLs and mine is the only one that does this.

After a week of searching for information my only theory is that the previous owner tried to change the top screen, but did not replace the HWCAL files (HWCAL0.dat and HWCAL1.dat), but I honestly have no idea (hopefully I managed to install CFW).

PD: Top screen is TN and the bottom is IPS.

I'm in the same boat, I changed the motherboard (which was upper IPS, lower TN), to a new 3ds XL with both TN screens and im getting the ghosting as well.
I have tried changing the HWCAL files, but no success so far.
Would be interested to know how you solved your one.

Did you manage to find a way to fix this? I'm looking for a solution too.

no,
i think my 3ds might have a hardware issue/damaged cable from disassembling it

I changed the motherboard (the screens are dual TN), the motherboard is top IPS lower TN

I tried various configurations of the HWCAL files but not change in the image showing ghosting/double image and reduced brightness when 3d enabled.

The 2D is fine, brightness and image are great.

I have the same configuration as yours, both TN screens but the motherboard is for a IPS top and TN lower. I've noticed when i use the rosalina ss3d tester that there are 12 parallax barrier positions available, numbered 0-11. If i move slightly to the left and right the test shows that the parallax barrier moves to the 0-2 and 9-11 positions respectivel, which is when the ghosting occurs. For parallax positions 3-8 the 3D is fine, so ive set my center position to 5.50, however this does not fix the ghosting issues that happen when i move to the 0-2 and 9-11 positions. I've tried replacing the hwcal files but to no avail, there must be a way to change the maximum available parallax barriers so they dont go past 3 and 8 when you move to the left and right.
