The fact that you can mount a flat-screen TV almost anywhere has spurred some creative solutions - from hanging a television amongst a mish-mash of framed artwork, turning the boob tube into a masterpiece itself, to installing a flat screen above a fireplace. The latter has always made me wonder, how safe is placing a $1,000+ gizmo above roaring flames? I did some research and found there's an easy to way to test that prized spot above the mantel for flat-screen compatibility.
Whether you've invested in an LCD or a plasma, running either above the recommended ambient temperature (between 90 and 100 degrees Fahrenheit) can prematurely damage the electronic components within your new, pricey, set. Here are some experiments to run before you start drilling into the wall above your hearth.
Most LCDs and plasmas are built to operate within a temperature range of 32 - 100 degrees Fahrenheit - you can find out where your set lies by checking the tech specs in your instruction manual. Practical Home Theater Guide suggests you tape a thermometer up where you plan to mount your flat panel, build a fire, grab a book, and let it roar for a few hours. Once your room's temperature has stabilized check the thermometer. If it's near or above 90 degrees Fahrenheit it's time to find a new place for your TV.
