If the lines are running top to bottom and are perfectly straight then your panel is failing.
The only repair is to have it replaced. It can be sent off and have the driver tabs repaired, but the sheer cost of that operation is far more expensive then a new monitor.
The next best option is to look for another monitor on a certain online auction site with a failed power supply and salvage the panel from that.
Even buying just a panel (new) will be more expensive or as expensive as a replacment monitor.

Sorry, it's just the way technology moves.
If it has any warranty left, then return it under that warranty. Most LCD's have a 3 year warranty, so it is worth checking up on. Look for the "Date of manufacture" on the sticker on the back of the monitor.

I had this problem around '08 and my monitor is still functioning in 2013. All I did was add a little piece of paper between the screen and the edge of the monitor. I pushed it up into the monitor so as not to see the little piece of paper and it solved the issue. It has been fine ever since.

Parallel vertical lines through left side of Panasonic Plasma tv


This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
