    On an otherwise fully functional Bg 4000 5215  I am getting the following behaviors:-

    1) when pressing the ^ button the tonearm does not stay up once the ^ button is released – it just drops as if the down button had been pressed.  Same behavior on < and > buttons – is this a keypad problem or should I be looking elsewhere?

    2) from time to time the tone arm drops suddenly instead of the normal smooth drop that is expected. This is not a persistent problem.

    Any thoughts and guidance greatly appreciated.

    Hi

    Cold be a keypad problem, regarding to the SM the \/ button is normaly closed and the /\ button is normaly open.

    So as there is a bad contact at the \/ button the tonearm will only stay up as long as you push any other button.

    Cleaning the contacts is recommended, look here for further information:

    Kind regards

    Just spotted this post justin, picked up a chest infection from soewhere ;¬(

    The tone arm dropping sharply sounds like not enough dampoing, try winding the srew in very slightly…..and I would check out the down switch contact…..if its playing up the tone arm will dot stay up when ^ is pressed

    Fixed.  Thank you Craig and Christian.  The down switch contact terminal was oxidized and bent – after cleaning and straightening it works a charm.  Tone arm is dropping smoothly now.  Sweet sounds are emanating from the deck and its owner.  Thanks again.
