Let me begin by saying that this is not intended to start an argument or debate. I do not favor one type of technology over another. I feel that they all have their purpose. I've just had a very stressful past 3 weeks and I think it's kind of ridiculous what TV manufacturers expect consumers to accept.
Let me start by saying that I have both LCD and plasma in my house for several years. I have been very happy with both. A few weeks ago I decided to ditch my Epson front projector as it was getting a little dated and get a TV a bit bigger than my 50 inch Panny plasma. To keep this short, I initially chose a 60 inch LG plasma(60PM6700) but exchanged it due to a defect in the panel. Hey, it happens. I decided to try out one of the new 3D LED sets (55LM6700). They gave me a healthy discount since I had to mount and unmount the plasma. There also were some delivery issues but that's beside the point.
Now this was a $1800 TV that I normally wouldn't have bought but did because of the discount. I loved the looks of the set, but it was usually out of my price range. I was quite thrilled to be getting it. Bottom line, I really wanted it to work out.
Set it up. Beautiful design, many features, 3D was amazing, but.......the flashlight, clouding and overall 2d picture looked like complete garbage. I spent a lot of time reading threads here before I swapped the plasma for the LED and figured it would be ok. When I returned the LED I was told that it really wasn't a defect but a preference that I didn't like how the picture looked. I got a refund and went elsewhere. I now have a 60 inch LG plasma (entry level, no apps, wifi, 3D, etc.) and the picture is far better than the LED for double the price.
Like I stated earlier, I'm not starting a which is better debate. My point is, from what I have read here, most all edge lit LED sets have clouding and flashlight issues along with uneven black levels due to the nature of the design. I really wanted a sleek new LED set but I couldn't live with the display. It pisses me off that LG, Samsung, Sharp, Sony, etc, etc sell $1500-$3000 products and can't even provide a picture free from distraction. But hey, they gave us apps, 3D and wifi. Oh, and it looks pretty on your wall. Just don't try to watch anything on it. It totally feels like we are paying to use beta products. You shouldn't have to run the panel crap shoot. It's not practical to have a retailer open every box so that you can choose the one with the least issues or return the TV 4 times until you get one that you can live with.
I do realize that full array solves some of these issues but seems to be reserved for the flagship models mainly. And some of those exhibit the same issues even with the array. Not that conventional LCD was perfect, but you pretty much can't find one anymore. Everything has been transitioning to LED.
But, I guess that's a representation of society today. We will pay tons of $$ for something that looks pretty but performs like crap.
