Hardware Crazy bot screen...

[hamak]

Hello everyone,
I'll need some help because my 3ds xl begin to be crazy!
It's like a mirror effect, I was thinking about a screen connection problem so I just disassemble my 3ds and reassemble it but nothing change...
Here a picture to show you the problem

But the more strange is that touchscreen and gamepad are working as before! When I push stick to left, it go right and when I touch at right in the bot screen it push the left side, everything is inverted with this mirror effect...
Any idea...?

Calibration?

It's seem to be strange that calibration can do this mirror effect no? :/

I've seen this happen with the top screen and the user just had to send it in to Nintendo. No idea what causes it, maybe bad screen, bad screen cable, bad board.

Ok but it's expensive no?
And they will maybe see that I open it..? :/
