Query: Poor contrast

Although I appreciate excellent sound and sharpness of the picture, I can't live with the poor color contrast on this screen. I fiddled with the adjustments, as advised by other reviewers, but to no avail. The dark colors look like amorphous blobs, and the contrasting areas have an unpleasant glow. There's no contrast control. I really wanted to love this TV, but it's going back to the store.
