Retail Nintendo 3ds

Product Name: Retail Nintendo 3ds
Nintendo 3ds turns on works but 3d slider is broken doesn't work it as is can be fix but don't have time once you fix that little piece it's a good working 3ds no charger for it I have a guy who fix stuff for me but he is out of town for a month and this is what he told me is wrong with it Okay, it could be 1 of 2 things, it could be that the slider is just loose or unattached from retail the switch that's underneath. The other thing could be that whatever sensor that makes it 3D is just broken or dead and needs to be replaced which Is a easy fix.
