I have had my TV in the garage for 4 or 5 years now with no issues. My garage is heated and air conditioned but I don't necessarily keep the temp controlled all year round for economical reasons. I just fire it up when I plan to be out there because it heats/cools so quickly. So, my point is, it goes through all the normal humidity cycles you can throw at it. I live in St. Louis, MO. Land of muggy humidity!
