Try calibrating it in windows. If you can't get any motion out of it in the Win Calibration, then chances are its broken. Next would be to take it apart and find the broken wire. They use very small wiresand at the "Solder points" they sometimes snap off. They are not to hard to find and fix. If you don't see any snaped wirers, then its a board problem and you'll ba in the market for a new joystick, CH is the best
Good luck!
