What happens if you lift the tonearm and slowly move it over its travel in toward the label area past the expected point at which it should cycle? There should be a mechanical click as it engages the lift / return cycle. If so, the mechanism works but might be out of adjustment due to wear and tear.
Perhaps cycling the Record Size switch a few times might have a positive effect on the function. There doesn't seem to be a user adjustment for the end of play cycle.

If you decide to venture into the mechanics be cautious, always protect the tonearm from damage and make sure you rotate the platter only clockwise as there are mechanical interlocks that could get damaged if you turn it the wrong way.
