Not sure if this is the right forum, but...
You guys have been helping me with constructing a subwoofer for a cabinet. This cabinet will house a receiver, cable box, etc. I have to run an HDMI cable from the receiver to the wall mounted TV. There's a bit of a trick to it, though. See quick drawing below. The red frame is the TV, the blue box is the power for the TV, and the green line is the cable I have to run. The framed structure is cosmetic and houses the gas fireplace. It will be covered in a 3/4" or maybe 1" stone veneer. So, I will have an electrical box that will be recessed into the veneer (I'm thinking this will allow the plug to fit into the outlet without pushing the TV away from the wall. I'm going to have the new thin Samsung that hangs very close to the wall.
So I understand that the only cable I'll ever need between the TV and the receiver is 1 HDMI. I'm trying to figure out the best way to run this cable so that it can be replaced in the future if necessary. Also, being able to run an additional cable if needed would be nice. So I'm trying not to reinvent the wheel and/or make a dumb mistake.
How would you go about running the cable in this setup, and how would you finish the point at which the cable goes through the stone? Please note from the drawing that the electrical box has nothing to do with location of the green line.
I hope this makes sense... any ideas are much appreciated. Again, apologies if this is not the right forum.
