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.

Blue vertical line appeared on samsung 740nw monitor


Make sure the monitor cable is secure on the computer and on the back of the monitor.
Try the monitor on a different computer.
If the lines are still there then contact Samsung for help.
If you are lucky your warranty is still active.

If this helps please vote for my solution.

Lines in screen


They are stuck pixels...

There are some that say sending strong images that change from to color to color can help unstick them, but I say only dissassembly and cleaning of the contacts (there should be 2 ribbon cables, one for top, one for side) that probably got dust in it. Call it in under warranty if at all possible.

I will assume the line goes from top to bottom and is straight.
If so bad news I am affraid. It is the driver tabs that go from the panel to the physical panel controller board and is not making correct contact.
This will normally continue to get worse until you lose entire bands of the screen.

Sorry for the nad news.

Screen Adjustment


On your monitor at the bottom there is 3 buttons. The one all the way to the left is the "menu" button. The next one (going right) is the "NEGATIVE" button. The next one (going right) is the "POSITIVE" button.

You can move your screen around. First, start by pressing the menu button.Then, a menu in blue, with a bunch of little white icons will appear. Next, go over two icons by pressing the positive button twice. Then, proceed to push in the "menu" button again. A bar will appear. By pressing your negative button, your screen will move left. Pressing your positive button will make your screen move right. Adjust your screen until the black on both sides are of even proportion. Then, press the menu button to return to the orginal menu you started at. Proceed to press your positive button two more times. Then, press your menu button. Then, once again, use your positive button, and your negative button to adjust your screen to even out the black on the top and bottom.
