Hi, just picked up my 46XBR4 and I too have the flashlights issue, although it seems to be from almost every corner! It's almost unbearable and without crushing the black levels, there's almost no way to get rid of them that I can find.
Should I just exchange it and hope for a better one?
Also, does anyone have any calibration settings for the Wii? (Specifically Motion Enhancer and Cinemotion, I'm guessing "off" for both)
Also, when I turn it off or on again, it makes odd popping noises for a few seconds like bulbs being turned on and off. It's odd and even though I sell TV's I've never heard one do that before (except the initial click of a plasma).
