Problem with Philips LCD TV

    There is a Philips 26PF8946 LCD TV set. The problem is that, from time
    to time, it displays vertical stripes on the right side of the screen
    (about 5 inches). They can appear in every mode (tv, teletext, video
    input). Their width does not depend on the mode (16:9, 4:3 etc.) It
    takes a couple of seconds until the stripes become stable. First there
    appear solid coloured rectangles (like in MPEG compression). Then the TV
    copies one row of pixels from top to bottom. Vertical stripes last for
    some time and can disappear automagically or you can remove them by
    turning the tv off and then on again. Stripes preserve their colours
    even after switching channels or to teletext. It takes some time until
    the problem appears after first use of the tv during a day.

    Does anyone know what it could be? Guarantee is already void, so I don't
    know if I will use an authorized service.

    Thanks for help.

    It's probably either the column drivers or the flexible ribbons that bond
    the drivers to the panel. If it's the latter, you *might* get lucky and be
    able to wedge something in there to make it work, but if the drivers
    themselves are bad the set is pretty much scrap.
