Why do some of my blacks look blue?

[SDon1969]

Is your Sony a LCD TV? When I first bought my LCD I had blue-colored blobs in some dark scenes, often times right on a character's face (Saw IV, for example). Forum members here described the problem as ghosting, I believe, and I was able to minimize it to the point where it was no longer distracting with my TV picture settings (I don't remember which setting, specifically). I saw a lot of this in The Orphanage, even after tweaking my seetings.
