The 43" Skyworth TV that my senior parents are using recently died. A replacement (used) logic board costs 3-4k but there's no saying how long it or the other parts will last so we're probably scrapping this.

Suffice to say, I'm looking for a brand new TV. The size should be 42-43" as it needs to fit the existing space. 'Smart' vs 'Dumb' is not a deal breaker as I plan to reuse the existing Roku 3.

I'd be happy with a basic but reputable and reliable TV, even without the bells and whistles. In fact, FHD (1080p) is fine.
