I'm looking to get a flat screen TV for my basement and have it wall mounted. The problem is that I have a knee wall (foundation block) that I need to deal with for running the wires. Do any of you have ideas on how to run the wires down through the wall and get past the ledge obstacle without cutting out extra sheet rock? On a regular straight vertical wall it would be no problem, but I'm a little stumped. If you have any links or pictures, that would be great.
