Not sure why this would happen all of a sudden, but one of my Dell 2001fp monitors has started showing a band of translucent blue lines on the left side. The lines are about one pixel wide, and there's a bunch of them (top to bottom, for the full monitor height) that cover a width of about 1.5 inches.
I haven't disconnected or reconnected anything in over a year, and nothing seems odd about the monitor settings, which I also haven't changed. the rest of the monitor picture is fine, without any color distortion at all. I can see the desktop icons on the left side of the screen, but having that set of blue lines there is annoying.
Any ideas about how to get rid of these lines, or is my monitor dead?

I have four Dell 2001FP monitors. The unavailable contrast is standard for this monitor when used with digital input (DVI). Make sure your brightness is at 100%.If you want a better result of dynamic range and color, the only effective option is color calibration. I use the inexpensive Huey Pro, available several places, including eBay. Retail is around $100. It something one uses maybe twice a year, takes five minutes to install and use, and the results are notable. I'm a designer, and need excellent color. This is the best solution. Calibrate your laptop as well, and the color should be almost exactly the same between them.
As an alternative, you can use the color settings, select User Preset, and start with something around 40 red 43 green and 37 blue. Adjust proportionately upward until you get what you want.
Another possibility is to use a different connector cable if your laptop has that option, since your monitor an take four different input formats.
I'm having the same problem... there's also going to be about 5 years of dust sitting in there, so I hoping it might just be a failure of convective cooling. My first attempt to remove the bezel was unsuccessful, so I wasn't able to go in and look for any swollen capacitors or such. I have blown canned air in the sides, and it's actually doing a little better right now. Probably won't last... having a rather warm summer.
This is heat, and is a common problem; it affects two of mine. You can verify this by having a can of Dustoff available and catching it when it first starts. Blow in at the top of the monitor through the holes in the back in the same region as the band. The color aberration should go away.
My solution was to make a shroud from black foamcore and use a spare power supply fan to blow air into the case at the top. This has worked for my two monitors for about 18 months. You can also just buy a 12v computer cooling fan for this purpose.Should be somewhere around 75mm in size and quiet, 'cuz you'll be putting up with it if it's not.You can either get a general 12v power supply, or an adapter that fits the 12v power out at the back next to the USB input connector.
The lines could be caused due to the disturbance in its radiations.in other words,look around the monitor to find if any other gadget like a Microwave Oven or Magnet is placed. You can see if there is any leakage that ends up dropping water on the monitor. you can see if the air cooler or conditioner or heater is directly blowing air on the monitor which could cause this to happen.
If you want to Isolate if the issue is really with the monitor or not, you would have to try out another monitor at the same location and observe for 24-48 hours.
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.
Just had the same issue with the horizontal lines. In my case, too, turning off the monitor would make it go away for a while. called Dell, turned out it was still under warranty (3 years), got a replacement monitor the next day. Way to go Dell!
