Late answer here, but this is my experience with my Q70T, where I found three dead pixels. They are always black and does not seem to work since they don't lit up at all, hence they are "dead".
This is generally bad according to many users (myself included). Although I know that this is a part of the LCD-technology and can happen to all sorts of TV-brands.
Why I won't return the set is because of the following:
- The three dead on my TV are spread out at "good places" (one far up in the left corner, one far up in the right corner and one far down in the right corner - all of them very close to the bezels. In other words: Not in the field of view for me.
- They are only visible if I sit straight in front of them at really close range, less than 1 metre (3.2 ft) from the TV. Since the TV is quite large I sit around 2,7 metres (8,8 ft) from the TV - where they are not visible at all. One of them is also only visible when looking straight at it and changing the position makes it "dissapear".
- They are only visible when there is a very bright and static background, which I do not really count as normal use - but more of a test-environment (dead pixel finders on YouTube for example). In normal viewing/gaming from my distance they are not visible. In fact, I would probably not even have discovered them from the start if it weren't for me cleaning the set with my eyes more or less in physical contact with the TV. Would they have been red or green it would probably be worse...
It is difficult with new TV's today as many seem to suffer from either banding, dirty screen effect, dead/stuck pixels, blooming etc. Many users don’t notice this as they are not actively searching for them, or not using them in ways were the problems get noticable.
Why we notice these things more and more is because we are using them in so many more ways nowadays (gaming etc) - and the picture is so sharp that we notice things more easily. Add to this all the threads on user forums, YouTube etc, which leads to people looking for problems they did not notice before. On this forum for example many people seem to have zero tolerance. Finding one dead pixel means returning the set, then the new set has DSE - and a that set is returned as well. I have seen people go through 4-5 TV-sets before people are happy.
Because of the famous "panel lottery" I took the decision not to go through the hazzle returning the set, as the next set might be even worse. I am more sensitive to dirty screen effect than a couple of dead pizels that is not visible from where I sit.
All this being said, it is really sad that we encounter all these different problems today, but this is the world of LCD-technology. Every manufacturer has these issues; Samsung, LG, TCL, Sony, Philips etc.
My only concern is that the dead pixels will spread.
