    Anyone know what could cause this?

    I received my new 42H81 from 800.Com delivery yesterday and when I finally turned it on there were these three ribbons right at the top center of the screen, really noticable. There is a red and blue and yellow one right next to each other about an inch and a half long and 1/4 inch thick. It looks almost like there is a piece of scotch tape inside the unit that is reflecting the light from the guns. The toshiba rep I spoke to on the phone said to do the 9 point convergence, but all that did was make the ribbons sharper.

    To 800.com's credit, their CS has been excellent. They will drop off a new TV and pick mine up free of charge. Still I am curious what would cause such a thing.

    Do you have a digital camera? Could you post a picture of this problem?

    Probably some foreign matter (Scotch tape) or imperfection (mirror crack) not at the screen but in the light path before. All three CRTs' light beams are hitting it in a fashion that when the light beams arrive at the screen, the shadow is in a different place for each beam.
    If it is tape on a mirror, there is a good chance that peeling it off would leave a residue. Then whoever cleaned it would have to be careful not to scratch the mirror. Many mirrors inside RPTVs are "first surface" which means the silver will scratch very easily.
    Since you would void the warranty by opening up the TV yourself to see where it might be, you might as well have them replace it if that is already scheduled.

    OK, I managed to take a picture of the defect and post it. Hopefully it will work.
    What do you think? Pretty noticable huh?

    There is a ribbon shaped object which is casting a shadow inside the set. By the shadow's appearance it is probably pretty close to the mirror. The close approximation of the color images to each other, the sharpness of the effect, and double imaging of the defect all point to something hanging down just in front of the mirror. A serviceman should be able to correct it in ten minutes by pulling the screen and moving or removing the offending object.
