When deciding where the TV will go, know what you're getting into--literally. Find a spot on an interior wall, out of direct sunlight, with at least one stud to anchor an LCD, or two for a plasma. Use a stud finder to check for obstructions in the wall. That's important, because the secret to a clean, â€floatingâ€ installation is to run your audio and video cables behind the wall and pull them out down by the floor, nearer your receiver. Include an extra set of cables so that you can add components later without taking down the TV.
