    It looks like the new 29N9 direct view TV models from Toshiba (Digital 100Hz CityFace) have a noticeable distortion of the horizontal lines,
    meaning that a straight line in the source picture is curved at the edges of the
    screen towards the center.

    The word from Toshiba customer service is that all flat screens show this
    behavior, and that there's no way of fixing it.

    have anyone else noticed this problem on a direct view (not rear projection) flat
    screen from Toshiba or Sony ?

    All CRT TVs (direct view and rear-projection) have bad geometry. It goes with the territory. If you get a good one, you're lucky.

    Pity reviewers never notice.......

    Why is it that manufacturers can make cheap, mass-produced PC monitors with better intrinsic definition and better convergence and geometry with an array of user controls to fix any distortion......but they can't do the same with TVs?

    Well, The manufacturer promotes this product as a state of the art technology (http://www3.toshiba.co.jp/ddc/eiji/frame00_e.htm) promising quality in all respects.
    But this new TV has worst geometry then a 15 year old set I have.

    The amount of distortions can be measured.
    Isn't there a specification or a standard agains which is can be compared ?

    It's frustrating when the technician claims "yes the lines are curved, but all the screens are like that, we can't fix it, we will not replace it, and we will not take it back"

    This is a brand new set from the box.

    Ring up directory enquiries and ask them for the phone number of Toshiba's UK registered office - not the helpline, but the HO switchboard.

    Ring the said switchboard and ask the operator, politely, and without mentioning why, the name of the Managing Director. Make sure you write it down, carefully, and check the spelling.

    Write a very polite, calm, letter, personally addressed to the MD and the registered office address. Describe, briefly, but with measurements, the problem. Tell him how you value his company's reputation and that you're sure this isn't what they feel they should be supplying. Tell him, politely and calmly about the refusals of help you've had from the dealer and/or from Toshiba's helpline. And ask, apologetically if he can help you out of the situation.

    Quote your home and daytime telephone numbers - just in case they need to clarify anything with you.

    (Most MDs have a department specifically designed to deal with personally addressed letters, and, in most companies, when this Dept says "jump" to the technical people, they "jump". It worked for me with Sony).
