Thanks 777funk,
I have the Yamaha EL40 out in the shed and when the weather gets warmer I will open up the organ and see if a retired motor mechanic can endeavour to discover what the problem is
Don't know if parts are available in New Zealand----- One step at a time.

Actually I have waited nearly 11 months for a Yamaha person to give a better idea what the problem is
Its a pity you cant turn the touch sensitive function right OFF.

Thanks from Dave L.
