Can I mount a LCD (40 inch / 50 lbs) into cinder block hosting a wood burning stove's chimney?

Please help me assess the possible installation of LCD screen on family room wall. It's a ranch house, the wall runs orthogonal to attic joist. It the longest interior wall, I assume it is load bearing as the wall devices one leg of a ranch home configured in an L.

The cinder blocks host a chimney flue for a fireplace. The blocks are behind wall board. No studs are in the wall here, just the cinder blocks. Either side of chimney there is dead space with lots of old wall board (as seen from the attic). In the crawl, the base of the cinder blocks are easily seen.

The chimney (30 years ago) was masonry, 10 years ago it was lined with (insulated) pipe for wood burning stove.

If the TV can be mounted and secured into cinder block, (and I decide to install over the fire place) let's ignore the issues of temperature and smoke,

What sort of screws and anchors does one use? (size type).

Other mounting advice?

thank you

You LCD can be mounted using a universal metal mounting bracket that connects to the TV in 4 places. I would bolt a piece of 1/2" plywood to the wall using spring loaded toggle bolts to creat an attachment surface. The metal bracket can be attached to the ply with either screws or aditional toggles bolts. The plywood helps to distribute the weight over a larger surface.

LCD's are pretty light. You should be able to use concrete screws. They need to be long enough to penetrate at least 1" into the concrete block. You drill a slightly smaller hole with a carbide masonry bit, and they screw right into the concrete. Use as many as you have holes in your bracket. Well, 6 or 8 should be enough.

A word of caution... You can strip the hole fairly easily, so just snug them up.

The best advice is to go to Lowe's

Dodgeman, I just read your 4 posts since joining the AMHD site. I see you left no person message or e-mail for us to communicate with you so I'll just use this post. Please start to familarize yourself with how this site operate before you start giving Experts a negative report on their answer as "inaccurate" when you may just have a different opinion or are asking a question. You gave me an inaccurate rating on an electrical question recently and I think that your information is very inaccurate. In your negative rating of me you said that you can touch a hot wire and not get shocked, have you tried this lately? Unless you are bone dry and hanging from that wire you will get shocked since you are always at least partially grounded.
