I got a new set from Costco and swapped it out. I don't want to Jinx myself but so far so good. The flash lighting on startup is much better, shuddering I was experiencing seems to be better and so far it hasn't shut itself off
One interesting thing I noticed. Some of the factory default values on this set are different than my previous one. Previous set was one of the first made as it was the first one sold from my Costco. I'm guessing they did some updates to the factory Defaults after production had started.
Only problem I had is some adhesive being on the screen which scared the crap out of me as I thought it was scratches. After some sprayway and microfibers I finally got that under control. Television updated itsself to 1.1.4 just a few hours after being up and running.
