    Viscount Jubileum 227 push-buttons problem

    I have a Viscount Jubileum 227 digital organ from a pre-owner. The organ plays perfect, but there is some problems with two push-buttons. In the front of the organ below manual I there is some push buttons for the memory bank and one push button "ENC" for the master volume for the organ with the swell only. Many Viscount models have push-buttons like this.
    The Memory bank no. 3 does not work and the same goes for "ENC. The pre-owner never used those functions, and did buy the organ new around 1996.
    Can I fix it with som kind of claening, or must I replace the unit for the push-buttons?

    I have found out, that the push buttons are Rubber Conductive Button Pad with light. I do not know if (rubber)buttons like this can be cleaned, or it has something do with the missing light? The schematic service manual is not very helpful about this.

    The rubber conductive button pad has to make some sort of electrical connection at some point along the way. It's possible that the electrical connection is a 'cold solder joint' meaning that the original soldering wasn't allowed to flow sufficiently (not enough heat) to make a complete connection.

    Have you tried tracing the electrical path (please power down the organ before doing this) with an ohmmeter? The schematic may show the contact points and there may well be labeled contact points on a circuit board.

    I did fix the problems by cleaning the (rubber) push button. Now all buttons works perfect.
    It is easy to get access to the push buttons under manual I.
