How do I wire my wall-mounted HD TV?
NEC 725.55 does not allow you to run class 1 cable in the same raceway as class 2 &amp; class 3 cable, so you'll have to run a new power cable outside of the PVC conduit that holds the audio/video cables. 

The best way to accomplish this (if you still want to use your SmartStrip), is to use one of these guys.



You'll install one hookup behind the media cabinet, and install the other behind the TV. Next, you'll have to pull properly rated cable between the two boxes (outside of the conduit). Once all the connections are made, you will be able to plug a short extension into the SmartStrip, then into the outlet behind the media cabinet. Now you can plug the TV power cord into the outlet behind the TV, and still benefit from the SmartStrip or other surge suppression device behind the media cabinet.

Unfortunately, you're going to have to cut a couple holes in the wall for the junction boxes. However, if you use old work boxes you'll only have to cut holes large enough for the boxes to slide into, since they don't need to be attached to structural members.
