Remember that until late last year, Roku did not build the TVs, they only provided the operating system. So it's really manufacturer dependent. I have two Roku TVs still in use, although they are only being used as a computer monitor at the present time. One is a 24" Insignia (Best Buy house brand) that I bought back in 2015 and the other is a 43" 4K Sharp that I bought in Oct 2016. And this one was shipped cross country as baggage on my flight home from a work detail in DC. Both still work just fine.
