Freezing an LCD TV

I am wanting to put a 50 inch lcd tv in my cabin. The problem is that I don't keep the place heated when I am not there in the winter. It's not uncommon to arrive at the cabin and the temperature inside is 20-30 degrees below zero. Will this damage the tv? I would assume it "should" be OK if I make sure it is warmed up before turning it on.
Any opinions???
Thanks!
