I installed a Commercial Electric 5053-WH recessed multimedia box
behind the TV in the master bedroom. I cut the hole in the drywall, and
ran a fish rod up from the basement. I used the fish rod to pull my
flexible fiberglass fish tape downward. I then used the fish tape to
pull 14-2 wire for power into the Commercial Electric 5053-WH, along
with a Cat5e cable for ethernet. I wired the power to an unused junction
box in the basement (previously used by an office that I tore out).
I ran the ethernet to the patch panel and connected it. Everything
appears to be working fine, and it's nice to have no cables dangling from
the TV. I put a pair of HDMI pass-through keystones in the recessed box
too, for later use with a receiver or Apple TV.
