I just changed one myself. £35 from www.digiservice.com
all you need is a decent 00size Philips screwdriver and a steady hand. Note, I don't do it for living, but I couldn't afford the ridiculous prices for repair. There isn't actually much to remove, although a couple of screws are tucked away.
JVC are still repairing this problem for free as well, but only until the end of this month (July). contact them on 0870-330-5000
