Roku streaming stick Mod #3800x bought at Best Buy Jan.8,21. Started heating up & doing some strange popping sounds about a month ago. Unplugged it & cooled off then replugged but became hot again. i have one on another TV (both Vizio smart TVs) which is starting to get hot but that's been there for about 3 yrs. Are these dangerous or only supposed to last a year or two?
