My assumption, is people are getting them regardless of this issue and that there is NO way any panel is better than the other, nor is there any way of telling which one is which. It's not a panel loto, its roulette. Take care
I bought a Samsung ES6100 (40") a few weeks ago from Best Buy and it had severe flashlighting and cloudiness. There were at least half dozen palm-sized blobs in the middle of the screen as well as flashlighting from the corners. Also, the left and right thirds of the screen were noticably brighter than the middle third, likely due to the edge-lit nature of the panel.
I made these evaluations in extreme conditionscompletely dark room when viewing a near-complete black background, keeping in mind that the backlight will automatically shut off entirely if the screen image is completely black. And yes, these issues were noticable even with the backlight turned all the way down.
Of course, in the daytime with a lot of ambient lighting, these issues were not visible.
As you eluded to, backlight bleeding issues are hard to assess on internet forums. Those who say their panel is perfect are likely not looking at it under the extreme conditions described above. Those who say their panel is defective maybe be looking at it too hard for flaws. And as you say, some panels will be worse than others.
I tried the reported methods of fixing the uneven backlighting described in this articlehttp://www.ehow.com/how_6516595_fix-...v-screens.html
I did not notice any effect on my panel, but you may try it as a last resort.
I wound up returning the set and got a Samsung EH6000 (40), which has a full-array LED backlight. This set had much better backlight uniformity, though not perfect; the eHow fix described above actually made it noticably better. I'm pretty happy with new the set!
P.S. I was one of the first people to report uneven backlighting with LCD panels (see my post history for proof). I had these issues with a 32 Sony LCD panel I bought in 2005 (paid around $1500!). There was a mega-sized thread discussing cloudiness with Sony LCD panels in which I described my experiences. The fix-it methods described in the above eHow article were actually derived from MY experiences suggested in that old thread. Nonetheless, when I recently was in the market for a new LCD panel and was doing research, I was disappointed to learn that these LCD uneven backlighting issues still exist. I would have thought that manufacturers would have ironed out these issues by now.
