Yep. Filter capacitors in power supplies are almost always aluminum electrolytic types, because the capacity and voltage ratings make other types too expensive (if the necessary ratings are available at all). Heat accelerates the aging process, and it gets very warm inside a television set. -- Mark Roberts Photography and writing www.robertstech.com
