Hi Mike,
Great news!
Armed with the trusty screwdriver, and your words of wisdom, I have stripped the unit down, rebuilt it and it is working better than ever!
You were right - I couldn't see it, but the connector was in the wrong way round.
Also, there was a short where the ribbon cable had chafed against the unit.
The upshot is that it is working...
