Question Is this a normal amount of clouding/torchlighting?

      Hi guys,

      I recently bought a new TV after our old hand-me-down finally crapped out. The old TV was a Samsung LN52A650 - a pretty beastly LCD from 2008. The TV looked great when it worked, and I don't recall noticing any discoloration or clouding on it.

      The new TV is a TCL 55S405. Granted it's a much cheaper set than the old Samsung was in 2008, but seeing as it's 2017 I figured the technology had just improved and gotten cheaper. I really like the TCL - viewing angle isn't as good as the old Samsung, but the picture is nice, at least once calibrated a bit. For $370 at Costco I couldn't pass it up. However there is one issue - during letterboxed movies and dark scenes in TV shows, I notice "clouding" or what is sometimes called "torchlighting" in the corners. It's not SUPER noticeable, but when the TV is completely black, I can clearly see 4 lights in the corners shining into the center of the screen, with a sort of dark circle halfway to the center. I've read that light bleed and clouding/torchlighting is a common issue with newer LED TV's. What I'm trying to figure out is - have I bought a lemon and is it worth exchanging, or is this an acceptable amount of clouding? I've uploaded a picture. The overall picture brightness is set to normal (separate setting from black level/brightness) and the backlight is set to 85 here.

      Thank you to everyone in advance for your advice.

      In my opinion that is not acceptable, but I have a plasma TV so it's likely I would say that! It does look worse than other LCD screens I have seen however. I would ask if the dealer is prepared to swap it for another. Good luck with it drcasino. Hope you get a satisfactory result. :thumbsup:

      In my point of view it looks like that bad screen uniformity and screen failures is more and more acceptable. Different types of tint, banding and more is rather common.

      To me, in many cases, it is production failures that lies behind the failures/problems. The quality management systems simply accept failures.

      When I buy a costly TV, I expect the TV to be without major failures, and nearly as good as the brand claims it to be.

      If a set is edge lit with a mediocre dimming system then this is invariably going to be the result.
      This looks like it's lit from the sides.

      Your back light is too high for LED TV. Try about half way or less.
