Wurlitzer Tarock

Hi
Have this machine, its from the year 1973, it was playing fine up to recently but now the pin wll not cancel, that particular record keeps playing over and over again, so i switched it off, i reset the pin manually but now when I turned it on and make a selection the search motor does not move the carousel and i can hear the motor running in the background, is there anything i should check or look for
regards
