I know how long your LED TV will last and you won’t like the answer
Something I find mildly comforting is that in an age when people are encouraged to replace their phone, fitness tracker, or computer every three years — if not faster — TVs haven’t succumbed to the same pattern. In the US, people typically keep a TV for well over five years, and sometimes up to a decade or more. You may end up holding onto yours longer than your car.
