Why I'm leery of ever getting a smart TV (in any way shape or form), I still watch OTA (Over The Air with an antenna). I keep recapping the power supplies & fixing what I can on my older flat screens as they seem more robust, & closer to a TV than a Computer.
The Roku Sticks, & boxes I have discovered are wonderful accessories or "components" to older sets, but I like to keep the set itself not integrated with the smart or internet device.
I'm actually in a fringe viewing area (meaning I have somewhat difficulty picking up my local TV channels now, especially since the last FCC Repack). I would be OK if the Manufactures even left the TV Tuner itself out of the set, & buy as a separate component, as there is a difference in TV tuners.
