I pulled mine out of my 1998 Aerbus, no big deal. There should be 4 screws (covered by decorative caps), 1 on each side and 2 on the bottom. Remove these, unhook all the TV cords, and you will probably need to use a putty knife or something similar to slide between the side of the TV and the housing. (Mine had kind of glued itself to the housing, but very easily separated)
With that, slide/lift the TV out! I built a mount in the open space and mounted a 32" LED TV, the fit was perfect!
