Re: vertical lines appear on my lcd monitor
I am a Dell Certified System Engnieer(DCSE)
you have to be sure if its an issue with the screen or operating system or video card
what you have to do is
turn off your system
now the moment you turn it on again start hitting F2 key
you will get system setup screen
if you see those lines here as well get the LCD replaced and if there are no lines
then try installing the latest drivers
or else you have to get the parts replaced
either the screen or video card
but in case you get display fine in system setup
its for sure your display is fine
These permanent vertical lines are caused by a fault in the LCD panel. Gradually occur with normal wear and tear as you use the LCD. The only solution is to get a new LCD unfortunately if its out of warranty.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

I'm assuming you're dealing with an LCD flat panel monitor.
If you've tried different input and from different computers and different cables, and you're still seeing vertical red lines, it's highly likely that the LCD is failing and there's not much that can be done easily to fix it. You will probably need to replace the LCD panel.
If the red lines are in different locations each time you power on, then it could be a controller board issue. But, if the lines are always in the same place, it's probably the LCD panel itself.
The vertical lines means you have failing T-CON board, part of the LCD panel assembly, it will get worst, new LCD panel will be needed. Westinghouse uses cheaply made screen like CheiMai, not LG/Philips. http://s807.photobucket.com/home/budm/allalbums
Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.
Some of the transistors or the connection to the panel inside the monitor are damaged. There is no absolute fix for this problem.
You can try pushing on the bezel (NOT ON THE SCREEN) of the monitor at the edge of the screen directly at the lines and you may be able to push the connection back together well enough that the line goes away, but usually in desktop monitors the bezel is too rigid to allow you to put any pressure on the connections at the back of the LCD panel.
It is the problem of monitor pcb in vertical section.check vertical ic for dry soldring. Resolder the ic if problem still on then change ic or check components related ith it. check continuity of vertical deflection coil.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
