    I recently bought a Samsung LN-S4695D 46" LCD television. In general I like
    the TV, except that dark scenes display vertical bars of lighter area
    extending approximately 6 inches in from each side (i.e., 6" wide bars on
    each end the height of the display) . This is especially apparent in
    16x9/full screen images. I have seen quite a bit of comment on Sonys this
    size regarding this defect. I guess I expected better from a $2500
    television. I'm wondering if some of the experts here would comment on this
    effect and any possible remedies. Is a set that has this problem simply
    defective/irreparable? I am still within the 30 day return period (Circuit
    City) but this is not an easy item to return, given its size. Any input
    appreciated.

    You might muck around in here or some adjacent forum and see if your
    model is discussed:

    Thansk Roy, yeah I've been on that one. There is discussion of the problem
    on the set. Apparently it uses the same screen as the 46" Sonys, which also
    have a lot of comment re: this issue.

    I'd like to know what the technical basis of this is. I gather it relates
    to the way the screen is backlit.

    Beyond that, I'm at a loss. Am not a techie. Just came across this
    while doing research as to what my next (first) LCD will be.

    Dan,

    Did you return your Samsung? I just purchased the same model on
    Amazon.com and am noticing the exact same problem. Is this a defect?

    Most likely just a design pushing the limits of the technology. LCD
    screens work OK up to 26-27" (with a few OK at 32"), but the consensus
    of Consumer Reports and the like is that for a screen larger than 32",
    you bite the bullet and go with plasma.

    We're 90% happy with our 26" Sharp: the view angle isn't a wide as I
    would like and large black areas are more dark gray than black - both
    typical of LCDs.

    'Twas that way once, but no longer. Read the March 2007 Consumer
    Reports. My family room is too bright to bite the plasma bullet
