Mitsubishi DLP light "bleeding"

[BStecke]

I just got this set yesterday. Great picture so far, but one thing that's bothering me is that light seems to "bleed" into the black bars on 2:35, etc. films. For example, in The Dark Knight at the beginning where the WB logo comes on screen, the white "spotlights" don't stop at the black bars, but are visible through the bars themselves. Pretty much anything that is bright that is right up against the black bars does this. Does anyone have any suggestions? This is the third DLP I've had, but the first I've seen with this problem, including any I've ever seen on display.
