This is how I was able to mount my TV.
My basement has hollow concrete block walls. The paneling is 1/4" thick and nailed onto 5/8" firring strips. So, the distance from the concrete block wall to the outer edge of the paneling is 7/8". (I put styrofoam between the firring strips.)
The problem was how to mount the TV to the paneling, which would mean that the screws would act like cantilevers, having to support all the weight at their ends.
The wall mount is a Sanus model, able to hold up to 100#. The TV is a Panasonic Viera 46" plasma; weight is between 75 and 80#s. When buying a wall mount for a TV, you have to know the mount can hold the TV's weight. You might want to allow for a future upgrade to a larger, heavier TV.
The Sanus screws were too short and would not work.
After researching the subject, I found the Tapcon Concrete Screw Company's website (Buildex Tapcon (http://www.tapcon.com)). I used their blue concrete anchors and drill bit to make the holes in the concrete block. I got these at Home Depot. I think they were 3/16" diameter and 2-3/4" long.
I used a hammer drill to drill the holes for the Tapcon anchors. Don't try this with a regular drill! I was very careful when drilling the holes not to wiggle the drill around, so that the screws would fit as tightly as possible. I decided to use a total of sixteen anchors to minimize the shear and moment hanging a heavy object onto them would generate.
I installed the TV in March, and it appears the installation is solid. Be aware that when you subsitute different screws from the mount manufacturer, you will void any warranty of the wall mount.
It sure beats cutting out a rectangle out of the paneling and installing the wall mount against the concrete block.
