This whole light thing is jogging my memory back to their LM series of 2012. Didn't their (47"/55") LM8600 have a long time bezel-logo light problem? I seem to remember someone actually having to get a USB flashdrive shipped to them to solve it. Perhaps I'm confusing this with Vizio, who had a similarly shtoopid problem.
If you believe you can win an argument by stating that scientists "often" get things entirely wrong, all you're doing is selectively ignoring the overwhelming legion of things they have gotten right. Viewed as an aggregate, scientists very very rarely get things entirely wrong.
