Pioneer DJ DDJ-400 2-Channel DJ Controller Portable - Powers On but is Untested

This is a used Pioneer DJ Portable Controller Desk DDJ-400, I am selling it for parts or repair because I have not tested it, all I have done it plugged it in and it turns on and things change when you press buttons etc but that is as far as I have gone, I did not set it up with audio or music.  So it is being sold as untested for parts or repair.  It has 1 knob missing from the back function (top middle) but this is easy to replace.
