Im having same problem, bought mine yesterday

I bought my 47lm6200 yesterday from best buy after returning a 46 inch Samsung. No Trumotion option, after wondering where the hell it was I found these threads. This is such B.S. I know it might say it earlier but how can you tell whether it was manufactured in February or whether it was manufactured in May, besides the fact that it doesn't include Trumotion. I was thinking about bringing it back and trying to get a more recently manufactured model. I need to know ow to tell when it was made to do that however. I cant believe this problem has been going on for months now. I'm starting to wonder if LG was a good choice.
