My 3D depth slider is not being detected as "Fully up"

First off, I'm not all that handy of a person.

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!
