cold weather impact on plasma/lcd's

Looking for input on adverse effect of cold weather. Will be installing LCD or plasma in a house that is unheated in winter when home is not occupied. It is a summer home used for about 7 months and located in NY where winter temps routinely go below freezing. Should I buy LCD or plasma for a wall placement and screen size of 42" ?

thanks

I know you stated an LCD/plasma, but I've read on the AVS forum that cold weather is hard on rear projection bulbs (when being transported) and one should wait a couple hours until the TV has adjusted to room temperature before turning it on. I'm not sure if this helps, but I thought I'd give you the info anyway.

If you're going to let the house go below freezing and stay there for a long period of time, be very careful with an LCD! Aside from the response time slowing to nearly nothing at low temperatures, if you actually let the crystal freeze, you can damage or permanently alter the characteristics of an LCD display that hasn't been designed for low temperature use.

The liquid crystal material itself has a lower freezing point than water and many LCD's are designed for storage in very cold temperatures, but check with the manufacturer of the display for the storage (not operational) temperature range to be sure.

Bring the temperature of either type of display back up slowly to avoid stressing the substrate itself. Don't operate the display until it reaches operational temperature, as you can damage all sorts of things such as the power supply and driver electronics if you power them up outside of their operational temperature range.

Hauled new Samsung 46 650 home in sub zero temps today. How long should I let it warm up before connecting? It was outside for a few hours. Temps as low as minus 5.

I would give it several (3-4 hrs. at that low an outside temp) hours to equalize with the inside temp.

I have a small LCD in my RV which sits unheated in the winter at well below zero temps. Always works fine in the spring when I use it afterwards. LCD's don't work well when cold, but I think cold storage of one is fine.
