Hi Tonyi,
This greatly depends on your environmental conditions. Be sure to contact an authorized Samsung service center for information if you intend to install your TV in a location with heavy dust, high or low temperatures, high humidity, etc. The operating temperature is between 50˚F to 104˚F. Operating humidity is between 10% - 80%. Storage temperature ranges between -4˚F to 103˚F. Conditions falling outside these ranges may lead to serious damage to your TV.
