I found this:
Samsung Plasma TVs can be stored at temperatures ranging from -4 °F to 113 °F (-20 °C to 45 °C). Storing a Samsung Plasma TV in an environment with temperatures outside this temperature range can damage the TV, even if it's not in use.And this:
Cold temperatures will do no damage to plasma TVs until they dip below freezing. The cold itself doesn't hurt a TV, which is why it can be transported and stored in freezing temperatures. But if you take a cold TV indoors and immediately turn it on, its electronic components can suffer irreversible damage.Oh, and don’t slip on the ice and drop it.
