Will it hurt a 42"lcd tv to be left in a house with no heat that could freeze?
Answer:
Please look carefully at Richard's answer but also
consult your owners manual and see what they say. If
you are real paranoid, wrap a quilt around the TV before
you leave to provide extra insulation.
By all means let the room temperature stabilize before
turning the set on (unless you enjoy the sound of a 30,000
volts arcing to ground, among other sizzling noises)
No, it wont hurt it. It's the other extreme that you would need to worry about - too hot. This is assuming of course that you don't take the tv and heat it up from the freezing temperature up to 80 degrees in a short time. This could cause condensation inside the electronics, which you don't want.
Ooo.I don't think freezing temperatures would be good for the liquid crystal in the screen. You might want to take it with you.
The liquid-crystal paste used in LCD displays has a different specific gravity than water, and its freezing point is much lower as a result. Keep in mind that many of the displays in today’s cars use LCD technology, in particular car radios and CD players. When was the last time you saw one of those crack when left out in cold weather? Just make sure your TV has warmed up to room temperature before you attempt to use it.
The typical manufacturer says -4F. The bigger issue is using it in freezing conditions. If you've had an LCD radio in the car or a GPS and tried to use it in below zero conditions (best people to ask about this are Minnesotans or people who work in high elevation..I'm pretty sure they aren't out replacing big screens in Feb) it takes time to warm up.
Keep in mind some TVs are stored in warehouses which can get extremely cold, but in your case for piece of mind you can get a nice cover made for it, and just keep it covered. When you come back you should just be able to plug it in (although if I shut down where I live for a long period of time almost everything gets unplugged except for a light).
