How Long Should One Let an LCD TV Warm Up Before Turning It On?

You Can Allow the TV to Warm Up

Because LCD refers to a liquid crystal technology, all LCD TVs are vulnerable to extreme temperatures. Ideally, an LCD TV should be operated in an environment no colder than 54 degrees Fahrenheit and no warmer than 104 degrees Fahrenheit. If you have recently brought your TV into the house from either an extremely cold or hot environment, it is wise to allow the TV to warm or chill to room temperature for a minimum of 30 minutes before turning it on.

The LCD TV Will Warm Itself While On

Because LCD TVs use vacuum tubes rather than old-fashioned glass tubes, there is very little danger with the tube being damaged by quickly changing the temperature inside the TV. Therefore, it is not necessary to allow an LCD TV to warm up before turning it on.

Bottom Line

Although a TV with a liquid crystal display needs several minutes of warming to achieve its best picture quality, this can be done with the TV turned on. So, unless you have brought the LCD TV inside from either extreme heat or extreme cold, there is no reason to warm up your TV before turning it on.
