This is a screen address failure from part of the matrix addressing. This can be caused by fair number of types of faults to cause a missing part of the addressing. You will not be able to fix this yourself.

Find out who the authorised local Samsung service is for your area. They will be able to give you an estimate.

i have a whie line going horizontal all the way across the sceen. how do i get rid of it?

Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

Hello,

All plasma an lcd TV 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 resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but 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.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works
