C24 Monitor/Pan problem

Working with the C24, I have not been able to get sound to the right monitor. I currently have the c24 in stereo mode L(1), R(3). In the Pan section the L(C)R is on but nothing shows in the display (and never has). I'm not even sure if there should be a display! I have performed all display, switch and rotary tests with no problems. It seems that the switches above the display are not communicating and not allowing the Pan section to work. Does anyone have any suggestions. Hopefully, its something simple like an incorrect setting.
