SOURCE: grey vertical line appears on screen

It's a symptom of what everyone refers to as vertical banding. Have you tried a light grey screen to check for banding? It may be that there is a brightness difference between two bands that causes the line to appear darker. You may also find that there is more banding in other areas of the screen than you have realized.

but there's no simple solution; though some claim that unplugging everything from the tv and unplugging the tv power for 24hrs will help. I think that's a crock, but you can try it.

do you have a warranty?

This could be a board or the panel. It is hard to say. Both can cause this. Have a repair shop check it out.

SOURCE: LG tv starts up with a grey screen with colored

Grey screen means the T-CON board is not getting the 12vdc feeding it, same for sound. So check to see if you do have 12vdc from the power supply first.

SOURCE: vertical coloured lines down right

No, gas problems would have generated failures all over the screen, not in distinct lines.
No, these lines are caused by badly functioning buffer boards: the chips on it that directly control those specific lines of pixels overheat and start to malfunction. The problem is getting worse because the status of the chips is getting worse: they need less and less time before starting to fail. In the end it will fail for good and those lines will be permanently on the screen.
The faulty buffer board will have to be replaced. You should call a repairman to do it - to access them the entire tv must be completely dismantled and this is a very tricky operation in a plasma tv. On top of that the replacement board is very hard to obtain by a regular person, it will have to be ordered at the dealer. Fortunately it's not an expensive part - less than $40 per piece.

Vertical black line, left of center screen, 3 inches wide appears when plasma tv is cut on.

You either have a bad buffer board or a plug that has gone bad. Being that the line is that wide I would almost bet that the board is bad. Have a repair shop check it out. Thanks

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..

Inspiron 1150 lines on screeN problem.

Connect an external monitor to the laptop and see if it also has the vertical lines. If the external monitor looks fine, then your laptop’s LCD display panel is bad. If the monitor has the vertical lines displayed on it, then your graphics card or motherboard is bad.
