I just received my 55" today. I love the thing to death already, but one thing is driving me a bit nuts. There is a slight vertical black bar that is visible during any point where the TV is black/dim. I took a photo.
Is this something that will get better over time, or should I have Amazon replace it.
That will not get better over time. It's likely a tolerance issue with the light guides. Do you have frame dimming enabled BTW?
But regardless of the reasons under it all, "Drives you nuts" == "You return it". You're paying far too much @#$%ing money to deal with being aggravated, I don't care how picky you might or might not be.
