Please help me resolve a problem with a Luxman PD-

There is a problem with the automatic feature of my Luxman PD-277 Automatic TT (circa 1980-82).

When the automatic feature is selected, the TT starts and the arm plays correctly on the record. However, at the end of playing the record, the TT arm lifts and returns to the tone arm rest. The problem is that after this cycle, the TT arms begins a new cycle and attempts to play the LP again.

This same problem, the TT arms begins a new cycle and attempts to play the LP again, is exhibited when the "cut" button is pressed when the TT is in automatic mode.

The TT operates fine in manual mode.

Any idea what may be causing this problem?

Any suggestion on how to fix this problem?

Thanks In Advance for your advice!
