Greetings to all on the forum (especially to you Fred!) this is my first (and hopefully not last) post.
I have a question that I hope one of the other Sansui enthusiasts here can help with in regards to the XR-Q9 turntable.
I have three of the beasts, but they all exhibit the same problem - the automatic functions do not work (i.e. auto lift, play and return).
Pressing the start or lift (cue) buttons causes the "computer" indicator to flash, and the platter will turn at correct speed, but it will never auto cue the tonearm or rotate it into the play position. Eventulally the LED stops blinking and the unit appears to go into a locked up state - the buttons no longer respond.
I have the service manual, and am a fairly accomplished tech insofar as amplifier and tuner repair, but the tonearm transport on this is very complex mechanically, to say nothing of the logic contol circuits involved in this model.
Does anyone know of an inherent defect in the design, or a common problem for which there was a techincal bulletin, or some simple/stupid problem that I'm overlooking? Note that nothing is broken (gears, sensors, etc) and everything appears to be mechanically aligned in the auto transport assembly beneath the tonearm inside the cabinet, but it just won't work and I'm at the point of being stumped.
TIA for any input
Kevin
