With the way my living room is designed, the best place for my 40" LCD TV with a surround sound system would be above the fireplace. I’m looking for advice on how to mount it to a brick fireplace and how to run and conceal wires going to and coming from the TV.
If the bricks are solid, there are a variety of masonry anchors available at the hardware store that will securely attach a TV wall mount. It will require some skillful drilling with a variable speed drill and a masonry drill bit, plus the installation of the anchors. But it’s definitely do-able.
The cable issue might not be too bad. Going inside the brickwork is probably not viable (especially that idea about chiseling out the mortar–egads!). But you can buy surface mount material at the hardware store that will conceal the cables.
Also, you can get away with only two cables, power and signal source (i.e., an HDMI cable from your satellite/cable receiver). For surround sound, install the theater amplifier on a shelf somewhere (with the cable/sat. box) and run audio directly from the box to the amplifier. You don’t need to extend it to or from the TV.
