My neighbour has asked me to wall mount her 37LG3000. No issues with the wall mount, but how do you get the swivel bottom off the TV. I have read on some other sites that once the swivel base has been put on the TV it is impossible to remove. I really find this hard to believe. My neighbour can't find the instructions that came with the TV. Anyone out there know if it is possible to remove the base? Thanks for any help.
