*** Thank you to everyone for their kind help. ***
I am pleased to report that putting a ferrite 'clamp-on' core at each
end of the 12V power lead has completely cured the problem. Because the
cable is quite thin, I managed to wind two turns round each core.
I wonder whether a screened power cable might have been an alternative
answer? Maybe I shall try that tomorrow.
Incidentally, before fitting the cores I did notice that placing a
finger near the screen did increase the noise.
