Vertical black lines appear, sometimes one and up to four of them at a time.
All plasma an lcd tvs have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They can sometimes be fixed, but it is a pain. An yes I have done it, and the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.
If it is a single line top to bottom?? sounds like a bad panel. the reason is if it were a buffer module it would run only half way. this is a no repair problem as panels cost more than the plasma. also this is common on a plasma. 3-5 years.
Your lucky day guys! follow this link and read carefully, it will work, worked for me perfectly!

I have a 42" Samsung Plasma, less than 2 years old. This black vertical line in the middle right about 4-5" wide showed up. It's always there, the only change that I see with it is that after a few minutes with the TV on a thin red line will appear inside the black one. I've read that it could have something to do with the address board but I don't have no clue what that means. Has anyone had this issue resolved and is it costly?
a black vertical line has just appeared today on my 37 inch dynex tv how can i get it fixed
i have the sony bravia 42"(?). black vertical line appears at the right edge of where the "normal" screen view meets the blank portion of the full screen. i only see the black vertical line when i use the full or wide screen mode. is there a cure for this?
My screen has a vertical arched black line to the right of the middle with sometimes smaller lighter appearing corresponding lines beside it. You can't see it on all pictures but it looks like a tornado coming out of the sky on pictures with a big portion of sky. The line looks "burnt into" the screen and is not on the surface. Help, its only 16 months old, out of warranty of course. Is it cheaper to try to fix or buy another?
Same problem with the vertical black line just to the right of middle on screen. Comes and goes with no apparent rhyme or reason.
