Will Fireplace Heat Damage an LCD TV Screen?

Updated February 21, 2017

A big screen LCD TV can be a costly investment, and naturally you'll want to keep it safe. Mounting an LCD TV above a fireplace can add an aesthetic touch to your living room, but there are numerous things you'll want to keep in mind before doing so.

Basic Warnings

LCD TVs produce a lot of heat, and use various vents and fans to cool the units down. Larger TVs will produce even more heat. A fireplace can add extraneous heat to the unit, which can damage its internal components. An LCD TV's lifespan can be significantly diminished if the fireplace produces more heat than it can handle.

Safe Temperature Zone

Heat up your fireplace, and wait 20 minutes for it to reach its maximum heat output. Place a thermometer in the area where the TV will be installed and check the temperature. The area is most likely too hot if the temperature is greater than 32.2 degrees Celsius. LCD TVs should only be run for a short while if the ambient temperature is higher than 32.2 degrees C, or you risk severely shortening the television's lifespan.

Solutions

You can still mount your LCD TV above the fireplace if the temperature is higher than 32.2 degrees Celsius, as long as you do not run both the television and fireplace at the same time. The combination of the heat from the operating TV and the heat from the fireplace will surely damage the unit's internal components. The television will be safe to run, however, if the fireplace is not on and fully cooled, or vice versa.

Cut-Off Temperature

The LCD TV should never be placed above the fireplace if the ambient temperature reaches higher than 46.1 degrees Celsius. Temperatures greater than 115 degrees can damage the internal components of the television even if it is not turned on.
