Welcome to dpc Rob, and to the FZ20 gang.
I suppose that the Image Stabilization may also be making some noise if you have it set to be in operation all the time. I have mine set so that it is enabled only when I half push the shutter button. I don't hear any constant sound from my FZ20 (but I went to lots of loud concerts when I was younger so your ears are likely more sensitive than mine, lol). Disable CAF and IS, and then see if you still hear the hum when the shutter is half-pushed. There should be nothing going on at that point once the green dot appears in the viewfinder indicating that focus has locked.
