I would not worry too much.
LED TVs, which are actually LCD screens, have a fairly broad operating temperature range and an even wider safe storage range.
Samsung advertises an operating range between 50 and 104 degrees Fahrenheit for all its LCD screens, including those with LED backlights.The storage temperature range is even wider. While your TV may not operate well in temperatures below 50 degrees Fahrenheit, to the best of my knowledge they can be safely stored in temperatures as cold as -4 degrees and as high as 113 degrees Fahrenheit.
Just make sure to warm them up gradually, so there's no condensation forming on the electronic.
