Out #6 not working

Yo,

I just spent the past 15 minutes of my life playing with different cables and fiddling with my mixer only to find out that that #6 of my 8 outs isnt working. I used two different cables routed to the #6 out, before connecting my headphones to out #1 (which worked) and then to out #6 which didnt work. I made sure that I had the proper pads routed to the proper outs, so I know I didnt mess that part up. My 2500 is less 6 months old, and I've only noticed the output problem just now. Can someone give me some info on why this may have happened and/or how it can be fixed? Any help appreciated, thanks

...Not trying to be obnoxious, but I just have no clue about how to handle this. And I tried a search, but put the words "8-outs" in a search and a million results come up

is it still under warrenty i would take it back.
or you can open it up and check out the solder connections.
