Can you imagine the time it would take to run display through every possible test to catch all of the issues that we are able to come up with on this forum. Then there is the interpretation of what level of buzz is acceptable and when. What are the basic tests they would run? When a car is manufactured they finish it on the assembly line and run it out to the lot where it is loaded up for delivery, next stop car lot and joe car buyer. On a white only screen, it is going to buzz. During normal viewing conditions it shouldn't be noticeable usually at normal volume levels, but even my mighty Kuro would have an audible buzz during bright scenes. I came to accept it because it did so many other things better than the alternatives. Unfortunately at this time every display tech has it's trade offs and some are just more sensitive to those tradeoffs then others. Good luck.
Your post is well taken. However, I was not referring to having every model individually tested. I know that that is not feasible. This issue affects so many of the models that I was implying that they had not really tested the models as a whole sufficiently. Like, if they make 50,000, they probably pull out 100 at random and test them. Out of those 100, a fair amount would have had this problem (and it would have been noticeable immediately - as soon as I turn on my TV, even if the screen is black, the room has an audible buzz. Going to the main menu makes it a lot louder). My point is, there is no way that they did not notice this, they must just not care.
It is easy to say 'just return it' but I live in a downtown metropolitan area and do not own a vehicle, let alone a vehicle capable of properly transporting a 50" TV. I had to plan in advance to get access to one, and to get i again will be difficult and a big inconvenience. You should not have to return panels in an attempt at a TV lottery. The product QC should be sufficient that it is very rare for an issue like this to present itself, but its not.
