Unfortunately, we can’t really comment on “how long these TVs last” since the answer can vary wildly between units and users. You could have 10 people with the same TV using it in similar ways but longevity could be different for each user. That said, we do hope to try and offer more insight on these situations in the future, which is why we’re currently in the planning stages of our new longevity testing. Feel free to keep an eye out!

We’ve had our 65U8H for 6 months, set-up in our elderly parents’ room, running DirecTV satellite/cable only (no streaming), everyday, and have just recently noticed, perhaps due to the weather being warmer and the A/C being on, that our 65U8H is averaging/radiating approx 104~108+ degrees all over its front panel (measured with one of those hand-held pistol-grip digital thermometers). And approx 108 degrees at the entire length of the sets’ rear/top vent, and 96~99 degrees across its middle & lower rear, mostly. At those high temperatures…. I’m thinking that the electronics will prematurely cook and die, probably sooner rather than later. =((

In comparison, our Sony’s (X900 & X930) measure temps of approx 99 degrees (F) all over their panel front surfaces; with their panel rears feeling too cool to bother measuring.
