I just mounted my Panny 42" Plasma on the wall and wantto run the wires through the wall now. I do not want to add a outlet in the middle of the wall so want to run the power wires in the wall. I do not have any insulation so I thought maybe about just dropping a metal conduit thru the wall and run the power wire through it? Is this really that much of a fire hazard that I cant just drop the tv power wire inside the hollow wall? Do I have to use conduit? Any other recomendations?
