On my Itasca Cambria the moldings around the TV are fastened with tiny screws that use an odd shaped bit to remove. The bit is readily available at HW store. I have had to remove my TV at different times to access the roof mounting hardware. My coach does not have an overhead bunk but an entertainment center. If stapled, plastic moulding removers for automobiles are available at HF and can easily pry the moldings loose without damage if you go slow and work from one end to the other. Again, my under sink cabinet needed some attention and needed to remove stapled moldings. As far as your TV, can't help with that.
