Most manufacturers spec their LDC and LED TV storage temps at between -4F and 113F (20-45C). I see a lot of discussion on various forums about bringing the TV in during the winter in the northern states. However, I see none about bringing it in during the summer in the southern states. I would imaging that the temp in trailers left outside in Arizona, Florida, etc in the summer could easily get above 140F. That is way above the spec of 113F. How many people in the southern states bring their RV or boat TV into the house in the summer? How many trucks have heaters to keep the TVs warm when delivering them to stores in the north in the winter? They could easily sit in a truck for a few days at temps way below -4F.
