slide out cable issue

thanks for the suggestions. after removing 3 pieces of internal trim, I got to the cable system. one of the end nuts had vibrated off. after loosening a cable, was able to return system to good working condition. I nicely screwed the trim back into place, as over time these cables will need to be checked and or adjusted. now I can gain easy access to the whole cable system. rv units really should have been assembled in this fasion.
