my 8 year old 40" sony tv is due replacement. What I like about the new tv's is that the screen goes right to the edge. I can get a 49" that will physically be the same size as my current 40".
I've always bought Sony but this thread is swaying me towards an LG. My current tv shows the backlight in dark scenes. Getting true blacks in a new tv is one of the reasons I want to upgrade.
