LG Plasma TV Vertical color lines, fixable?

[Sevenqi]

This is a LG 50" Plasma TV, model LG0-50PK250, it developed 2 vertical grey/blue lines on the center of the screen weeks ago, now another line on the right side of the two lines.
These lines are not black, so it seems it's the column driver board issues, but I'm not sure. I attached the photos to show the problem, we can see on the White Wash Mode(third photo), no lines, on the Color Wash mode(Last photo), the white color block will not show lines.
Any one has the same problem before, is this problem fixable? or just simply replace the middle column drive board (3 of them at the bottom of this set).

Not repairable sadly; the panel is bad.

Hi, when you say panel do you mean the main board?

No, the actual plasma glass has failed. There are thin driver chips embedded on ribbons attached to the plasma panel. When the driver chips fail, the plasma panel is scrap because you can't replace the ribbons (they're bonded to the glass.)
