If you see "fractured lines" across the screen, it would appear that your LCD screen is broken. That's the only way these kinds of lines appear.
You need to replace the screen.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

SOURCE: my dell e196fp lcd monitor has white lines

Dell had a problem with horizontal lines in some of their monitors a little while back. I would try contacting Dell Tech Support to see if your monitor is one of the one effected. I think they were replacing the monitors that had the problem, but I'm not completely sure.

White line across screen


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.

Take it to a repair shop.

Monitor flickers with lines across screen


screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

MONITOR HD2200. I TURN IT ON AND THE SCREEN GOES WHITE THEN A FEW VERTICAL COLOR LINES APPEARS AND AFTER A FEW SECONDS IT GOES BLACK.


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hope this will help out in solving the problem....

Screen goes blank after a few seconds


Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.

A white line across my screen


It could be one of three things, the first two could be an easy fix, the last one calls for a qualified repair person and could cost you

-first, The lcd cable assembly is loose, make sure it's seated properly. if problem still exists try to Disconnect the monitor cable from the computer and turn the monitor on leave it plugged in to the electric socket.it will display a diagnostic colorbar are the lines still there. if not your problem might be a cable or video card. if they are still there have a technician evaluate the monitor.

-second, The inverter card may need to be reseated

-last, The lcd has a thin line crack and needs to get replaced

It would be helpful to know about the inner workings of an lcd screen and how to access them. It shouldn't be to difficult if your computer savvy. I want to caution you about getting shocked. an lcd still has power stored in capacitors. you should be able to drain those capacitors by leaving the monitor on and unplugging it from the electrical plug wait 10 sec or until all lights go out on the monitor.

If none of this works then Your monitor is defective, and nothing you can do to fix it... Call where you got it from for a replacement

Solid line completly across screen, monitor is brand new


Your comp's video card refresh rate (in Hertz, abbreviated Hz) may not be totally compatible with the monitor. Check the properties of your video card, and change the refresh rate (you may have to look around for it) to 60 Hz. This is a pretty standard refresh rate that works with just about every monitor. If it's already there, I'm afraid someone else will have to try and help!

Hope this helps, and please rate my answer, good OR bad.

Good luck!

Replacing the lcd screen more than likely. Problem in the PCB thats built onto the lcd itself.
They are rather inexpensive these days to replace. I would just buy a new one. Check warranties offered before buying, some manufacturers offer 3 years. ;)
