Thanks for the reply.

The spring hadn't fallen off - I last cleaned it months ago and it has been working fine up until yesterday (I then opened the keyboard up again today to see what I could find and the spring was mounted OK, though I did reclean it again at that time).  The note does not come on as stuck from the moment the keyboard is fired up, it is only once I have played the note.

As for cleaning the circuit, where do I find any schematics to see what board and which circuits I should be looking at?  This - including DX5s suggestion that a rebuild of circuits may be required - is starting to sound like something I'm not comfortable playing around with.......  What sort of specialist would do such work?
