It sounds like a bad panel, which is not what you want to hear. Replacing the panel on a Plasma TV usually costs more than just replacing the TV. However a bad panel causes vertical lines exactly as you describe.

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

Sony PFM-42B1 with black bar in 720p


yes, stop using a plasma TV as a computer monitor. Using the TV this way is an invitation to phosphur burn which these are very prone to. The issue you describe is due to the limitations of the TVs scaler circuit to properly center the image in 720P.

Vertical Black line on display


Rakesh, You have a "dual scan" panel, this is why the line only decends down the screen half-way. This could be a connection problem on the buffer board which causes loss of the drive signal only to that part of the display which it is connected to. The vertical address buffer will be located on the top rear of the display, use great caution in inspecting these cables and connectors. If the integrity of the cable and connector is good the panel itself may be bad due to the drive IC being located on the ribbon cable attached to the panel body. this is better known as COF or, chip-on-film technology. I hope this helps you. Good luck. Joe Weibel CustomElectronics.Org
