If the wood panel is hollow you may be able to get some small "brolley Bolts" These are available in various sizes and the beauty of them is that once fitted the screws (which would attached the socket face to the wall/panel) can be removed when required without losing the fixings.
I had a similar problem with a stud (hollow lathe and plaster wall) what i did was remove the socket and fixed with no nails -inside of the wall two small pieces of wood - then screwed the socket back to the wall and the screws bit into the wood I fitted....this worked quite well
Good luck!
