Just repaired one of these with the same fault. at the bottom of the plasma panel you will see a row of ribbon connectors, on the back of the ribbon connectors are some surface mount components. resolder these components on the offending connector, clean the contacts on the ribbon connector and reconnect. unfortunately getting to the connectors is quite a job, so give yourself plenty of time. if this doesn't cure the fault then the poor connection is on the plasma panel which you cannot repair, the only option then would be to replace the panel.

Green vertical line on videocon 42inch plasma tv

Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..

Black line problems

Some components in the vertical deflection amp have been going out of spec with age.

The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.

I would be considering a new set.
