Yes it has worked. Hadn't used it for a couple of weeks from when it was last working fine, and hadn't changed any hardware or software, but suddenly faced with the continuous red/green. Have manually reformatted and reloaded the card - still u/s.Interesting that you get the same effect with card out; I'd already opened the case and looked at SD contacts, wiggled and pushed - no different, but I'll focus on the card contacts again.
