Sounds to me like the belt has snapped or slipped off. Lift the platter off the table. On the inside of the platter you will notice a second ring, or rim. the belt should be put on the outside of the second rim while the platter is still in your hands. Next, slide back the platter and look for the spindle running the platter through one of the big holes in the platter. Slip the belt onto the spindle and turn with your hand to make sure it runs freely. Hope this helps
