Intro: Hide an LCD TV Behind Drywall

I managed to install a 6 inch deep LCD TV behind a 4 inch gap between main wall and drywall. I took apart a functional LCD TV panel (THOMSON model 42M71NH20 42 inches wide) and placed it behind drywall. Here is how I did it.

Step 1: Dissasembly

Every LCD TV is different and you need some prior experience with taking apart and putting them back together agian. I've fixed at least 5 laptops and several monitors, so I knew what I was doing. I carefully took the unit apart. I did not use force. When something did not immediatly disconnect I tried looking on-line and attempting to take that particular part again in a different manner.

Step 2: Testing If the Unit Is Still Operational

After I took all the insides of my LCD out, I connected all wires back to where they were originally connected and powered up the unit without the casing. I lay the LCD panel and tuner with power supply on the floor and turned it on. I was very happy to see the unit operational. I could now bring the parts to my appartment and start assembling the LCD behind drywall.

Step 3: Assembly

I attached the unit to metal drywall beams.

Step 4: Testing Functionality Again

After I fastened the unit to drywall beams I turned it on again to see If it all works fine.

Step 5: Setup Complete

And finally my setup is complete.

    I work for a custom home theater installation company.  When we install LCD in a wall behind drywall, the unit stays in one piece,  that way if anything goes wrong with the unit, it's still covered under the warranty. One thing you have to remember, ventilation. Your LCD will over heat if you fully seal it in a wall. Here is something that we do often http://www.htmarket.com/plscmasyfrar.html.
    Other than that, good job

    Pictures with the drywall finished? What did you do around the edge of the drywall? L-Edge? Zip-Strip?

    Here is how the LCD behind drywall looks now. Haven't installed the L-edge yet. Will let you know when it's up there!

    What do you do when it breaks down and it's embedded behind drywall?

    Can get almost the same look with a simple recess and trim.

    I can't tell from looking at the pictures, is there a way to use the video inputs after installing the TV?

    Actually, I have done similar mountings with assorted computers in the past.  I found that if there are parts that are seperated from the whole, mounting them on a backplane (i.e. plywood) one can route cabling safely and cleanly as well as make any extensions needed and then mount that to the wall before covering with sheet-rock.  I would take it one step further and create a patch panel for all the inputs, run cables, and mount that in an inconspicuous corner for a rack to put all the other devices (DVD, Game console, etc.)

    I think it is a great way to save space and give a room that 'Farenheit 451' feel.

    Great idea! I should have called this instructable “putting up a Farenheit 451 type display”. I'm running a whole bunch of wires to a spot where I plan to put all my computer/dvd/etc stuff.

    Love your ideia, But (there is always a but), you are not in compliance with te NEC code.

    that means if by any chance something happen with your house (doesnt have to e related to the TV), the insurance company wont pay for the damages.

    If Im not wrong you should have a meta box inside the wall

    Other than that Im looking foward to see the final product.

    congrats and cheers
