TV & Arial Sockets on Coachman Pastiche

[Scorpy]

Hi
Does anyone know how to get the TV Socket off the wall on a Pastiche? It is a bit wobbly and I would like to make it more secure but can't for life of me see how it comes out. Have tried removing the drawer underneath but no joy there, can't get to it from the Heater cupboard and there are no screws for front removal like a domestic socket.
Any ideas?

If it has a sliver surround, that is clipped on to the backplate.
There should be a small cutout which you use a flat bladed screwdriver in to unclip it .
It just presses back after.
