I am interested in this as well. My parent just bought a new 5th wheel trailer, which has a 20" or so Sharp LCD in it. Here in alberta, it is not uncommon to drop down to -35 degrees for a week at a time.
I told them to take it out for the winter (they wont use the trailer at all until May), but I am not sure if that is necessary. If it is not being turned on at all, is it a bad thing to have the LCD sitting in the cold?
