Recently I am noticing that my Samsung monitor has these horizontal "bars" across the screen when I am surfing on line. It happens when a web page is loaded, and the bars would align with the lines of text on the screen. Those bars are just a slight discoloration that run across the length of the screen.
When I close out the browser (Firefox) the desktop image does not seem to have the same problem. I tried using Explorer instead and those same bars would appear with the lines of text.

Line, faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent.
When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.
The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.
If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.
now if you can replace them your welcome but i wont suggest that , cause you may break it more....!
any ways do comment if it helped you in any manner!
disconnect all the cables except the power cable and then turn the monitor on you would see a test screen if it still happens your monitor is faulty and better buy a new one as repairing is usually expensive .also check you warrenty its usually 3 years
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.
Disconnect the monitor from the computer and turn the monitor on it will display a diagnostic colorbar are the lines still there. if not they are likely a cable or video card. if they are still there have a tech evaluate the monitor.
Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at.
This set is worked on in the home and does not need to be taken to a shop, so, you can still use it.
