LCD displays use liquid crystal fluid in the display. Like all other fluids, the liquid crystal fluid can freeze in cold conditions. It's important to be aware of what conditions can ruin your LCD display. Ideally, you should store your LCD in temperatures between 40 degrees and 100 degrees Fahrenheit to keep the liquid crystal fluid from freezing. You can still store the TV in colder weather, but there are some rules to follow.
Cover the TV with a blanket or wrap a piece of cardboard around it large enough to cover the screen. No matter what the conditions, your TV is always susceptible to being scratched while in storage, so it's important to cover the screen to protect it.
Store the TV in temperatures above minus 20 degrees F. Different manufactures have different weather limitations for their products, but, according to RV Road Trips, no manufacture has a temperature limit lower than minus 20 degrees.
Give the TV 24 hours to acclimate to the warmer surroundings before use if you store the TV in temperatures lower than 40 degrees. It's not a good idea to immediately take your LCD TV from extreme cold to a much warmer environment.
