I bought a Samsung LN52B750 last summer, and for a while I thought it was a great TV.  Then I moved into my new apartment and started noticing that the corners of the tv were bright during dark scenes or when just flipping channels etc.  I then did some research and found that this apparently is a standard problem with LCD.  As it stands now, I've tried all the tricks, lowering the backlight, etc but its done nothing.  I cannot watch anything without immediately being distracted by the backlight bleed whenever a dark screen comes on.  I'm not sure if when I moved (three blocks and the TV was placed in its original box) somehow we screwed something up?  I'm torn right now between selling the TV for a huge loss (I spent $2300 on this thing and I'm guessing I'd be lucky to get 1400), or just taking a complete loss and taking it apart so I can see what causes this problem.  Can anyone provide me with a technical explanation for this issue?  I've heard all the explanations about screen uniformity, but without pictures or seeing it firsthand I can't grasp why this problem exists - do the TV manufacturers just not care???  I'm seriously bummed out about this, I have a $2300 paperweight in my living room because I just cannot watch anything on it because the problem irritates me so much.  Is the only solution to buy a plasma?  Ugh, I'm venting but I can honestly say buying this TV was the worst purchase I can think of.

It's simply one of the flaws of LCD technology. I work with professional, studio LCD monitors and all of them exhibit the same problem to a greater or lesser degree.

 

The best way to minimize it is to watch with some ambient light.
