    Panasonic C?-27D20B: About 15 white lines taking up the top 1 inch of the 16 vertical inches of screen. They seem to display up-side-down whatever goes to the top of the screen. Other than that, the TV and picture are fine. The manufacture date is June 2000. I don't know how to fix it other than not pay attention to the top inch.

    My 27" panasonic has the same problem , 3" of top picture folded down.
    The picture sometimes is shifted up during letterbox display, then it shows a blinking white band @ bottom of display.

    Question: does this set have a vertical centering and/or vertical height adjustment? I don't have a manual so details
    are appreciated!

Suspect it's 1 or a couple of bad capacitors in the vertical deflection circuit the caps are in the 400 series, c400,c401,c402, etc... check or replace c414,c418 & c417

Is it still under warranty?
If not I would find a good TV Service Shop and have them check out the power supply as there more than likely a 'Capacitor' much like a battery that is going bad.
