I just purchased and mounted my 52lcd and I cut holes to run the HDMI cables behind the wall. As I was snaking the power cable, I realized this might not be the best way. Is there anything I need to do (I only have basic 'contracting' skills) to keep my install fire code safe?
Sorry dude you have me there... Running the power cable behind the wall is clear and ok but what has your install fire code got to do with running a cable behind a wall...??
The hole should be sealed for a fire stop.That little hole should not amount to anything.If you seal the hole and have a problem with the tv set you are really going to have problems removing the set for service.
