I press play, and the record starts spinning and the arm begins to move into place.  Before the arm can move fully into place, the record stops spinning and the arm moves back into the resting place.  I have tried manually turning the record, and when i do this the arm moves into place and plays, however when i stop manually spinning and press play, the record stops spinning.  Please help!
