I'm a fairly new installer and am needing help with installing a plasma above the mantle on a fireplace. Anyone have any ideas on what the best approach would be? Factors to consider: the fireplace is on an exterior wall, 2 story home (downstairs), there is no cable or power outlet on the fireplace, and the cable box, DVD, (source equipment) will be located in another part of the house. Obviously I will not want the cables to show. Any advice or direction would be greatly appreciated.
