My brothers controller ports dont work anymore. Anyone have any suggestions on how to fix it? The xbox is not modded and was purchased about a year and half ago. Thanks.

replace it

There's alittle circuit board for the controllers on the motherboard see if that might have loosened some how and if it did try pushing it back lightly. I noticed mine did that when I was modding my xbox. You gonna have to open the xbox up so if haven't done it beforehave someone else do it or read the tuturial on it.
