My monitor keeps on flickering and at times it just has lines on it. Eventualy it comes on but then it start all over again

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.
Check the cables, connectors and connections.
Take it to a repair shop.

If it's not under warranty, buy a new one from newegg dot com.

Check all your cables are plugged in firmly.

Alot of people has the same problem,

It is not an easy job, the lamps are real delicate to handle and they have mercury in them. You can look at bad lamps pictures here to get some ideas what is involved.

Hi,

A nearby device can cause stray magnetic fields that will cause the display to be affected. A problem inside the monitor will cause the display to have problems. If somebody turns on their monitor nearby, the monitor's degaussing when it starts up will cause your monitor to dance wildly for a moment or two.

keep electronics away from your computer. Mobie phones etc. can distort the image shown on the screen for periods of time, usually when a text or call is coming through.

Sometimes if the refresh rate isnt set high enough you will see a noticeable flicker on the screen .. to change the monitor refresh rate .. you can right click on the desktop and then left click on properties .. click on the setting tab then click on the advanced tab then click on the monitor tab ..look in the drop down menu where it says 60 hertz and see if the refresh rate can be changed .. if it cant .. uncheck hide modes the monitor cant see and then click on the drop down menu .. pick a refresh rate .. 75 hertz is what i use and it should stop the flicker

Answer well one major cause can be the weakness of the electron gun that fire electrons on the silicon plate (pixels) that produces image on the screen so there must be some problem in electron gun in my view

How do I change the backlight

ram problem once clean the ram and insert it again if the problem occurs again the change ur ram it will rectifye ur problem

chech out some other devices near by to the monitor, they might cause interfearence and in a result your monitor flickers.

1. If there is nay CVT/UPS near your monitor put it away.
2. If you have any speaker without magenetic sealed it will cause flickering, keep it away from monitor.

Otherwise your monitor need to be get service. So please contact your manufacturer service centre.

Thanks

1. Flickering screen display
   
   Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:
   • Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
     • a TV set
     • a laser printer
     • another monitor
     • fluorescent lights
     • hidden power lines
   • Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
   • Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
   • The number of devices using power from the same electrical line. Are you overloading the plug?
   • Monitor placed on an unstable surface.
   • Improper video drivers, this is a software problem, see section B
   • An improperly configured or a defective video card.
   
   
   
2. Reinstalling the video drivers
   
   
   1. Start the computer.
   2. Click Start, select Settings, and click Control Panel.
   3. Double-click the System icon.
   4. Select the Device Manager tab in the System Properties window.
   5. Make sure that View devices by type is selected and locate Display adapters and Monitor in the list.
   6. Click the plus sign (+) in front of both items to get a list of installed devices.
   7. You need to remove every device by highlighting it and clicking the Remove button and OK when the warning message appears.
   8. After doing so for both items, they should disappear from the list.
   9. Close the Device Manager by clicking OK, and you will return to the Control Panel.
   10. Double-click the Add New Hardware icon.
   11. Click Next, select Yes when it asks "Do you want Windows to search for your new hardware?", and click Next twice to start searching for new hardware.
   12. This will take a few minutes and, after it is finished, you will have to restart the computer. Windows 95 or higher will automatically set up the correct monitor and video drivers.
   13. If the screen is still flickering, click Start, select Settings, and click Control Panel.
   14. Double-click the Display icon and select the Refresh tab.
   15. Change the Monitor Refresh Rates until the flickering disappears.
   16. If the flickering remains, go to step C.
   
   
   
3. Troubleshooting
   
   
   1. If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.
   2. Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.
   3. If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.
