Samsung SP-P4231 vertical line f-buffer?

[matt@bdtinc.com]

I have a Samsung SP-P4231 plasma with a single vertical line (only about 1 pixel wide) running from top to bottom directly in the center of the screen. The line shows on all inputs and even on the on-screen menu. It is for the most part, a black line as it is not visible on black areas of the screen but it appears white when it intersects the on screen menu's blue bars and ive also seen it turn red. I have removed and cleaned the contacts of the F-Buffer with no change. Before I buy a replacement f-buffer, can anyone with experience tell me if this will likely solve my problem? Thanks!

Normally one single line out on the display is a failed Panel meaning its unfixable sorry. Can you get a picture of it ?

Hopefully the pic is in high enough resolution that you can see how it changes colors when intersecting the OSD. According to Samsung's plasma troubleshooting guide, a solid white or black line is almost ALWAYS the panel but "other lines that vary with content" are almost NEVER the panel.
I guess my question now is, in theory, could the F buffer possibly cause the vertical line above it? The part is only about $20 but i'd rather know for sure if there is any possible way to do that.

Ahh right, I would say failed panel sorry more than likely the address driver has failed. You can try a new F buffer to see if any of the nodes have become flaky and not making connection I personally wouldn't bother but up you mate.

COF Chip failure--Part of panel and un-repairable.
