This is most likely caused by small power fluctuations in the power board due to some capacitors that are failing. It is a common fault with LCD monitors and is easy to fix if you have some electronic knowledge.
If not, then I advise you to take it to your local TV tech and have them replace the caps.
They should not charge alot..it's a 15 minute job.

Hope that helps =)

My lenovo LCD screen is flickering black and striped lines, how to get it fixed in Richmond Hill Ontario


Laptop computers have LCD displays that are sensitive to many things. LCD displays have faults that sometimes produce a flickering screen, lines, dots or a faint display. These screens are sensitive to magnetic fields or electronic items near the computer. Speakers, cell phones, lights and other electrical items are examples. Your display also could be flickering due to software issues such as the video drivers or hardware issues relating to the inverter going bad or the LCD screen itself needing to be replaced. Trace the cause of your problem to come to a resolution.

1.Turn off the computer. Disconnect all external devices. Turn the computer over (bottom facing up). Take out the battery and reseat it. Turn the computer on.
2.Reset your resolution and refresh rate.
Windows XP:
Right click an open area on your desktop. Click "Properties" in the drop-down menu.
Click the "Advanced" button at the bottom of settings tab. Another dialog box appears. Click the "Monitor" tab. Change the Refresh rate to your default, or 60 hertz. Click "OK."
Windows Vista:
Click "Start, Control Panel." Find and click "Appearance and Personalization." Click "Adjust Screen Resolution." Change resolution to the default, or 800 x 600. Click "Advanced Settings." Click the "Monitor" tab. Change the refresh rate to the default, or 60 hertz. Click "OK."
Windows 7:
Click "Start, Control Panel." Find and click "Display" Click "Change display settings" on the left side. Change screen resolution to 800 x 600. Click "Advanced Settings" in the lower right. Click the "Monitor" tab. Change the refresh rate to 60 hertz. Click "OK."
3.Check the computer's surroundings. Move away any speakers, fluorescent lights, fans, cell phones, radios and any other electrical device that can cause flickering. Temporarily move electrical items away from the computer to see if they are producing this issue.
If the flicker stops, put back one item at a time to determine what is causing the problem.
4.Connect an external monitor to your laptop computer to see if that screen is also flickering. If there is no flicker, then the problem is strictly with the laptop, indicating a possible hardware failure. Contact the manufacturer for a replacement LCD.
If the flicker continues, go to next step.
5.Reset/Update your video driver. Click "Start" and right-click "My Computer." Click "Properties." The "System Properties" dialog box will appear.
6.Click "Device Manager." A list of items will appear. Click the (+) sign next to "Display Adapters."
7.Right-click the video adapter and click "Uninstall." Confirm removal. Restart the computer. The video driver will automatically reinstall itself.
8.Check to see if the flicker still exists. If so, go to the manufacturer's website. Download and install the newest video driver and BIOS for the computer.
9.Restart computer once drivers are installed. Continue to the next step if there is still flickering.
10.Open up your display screen all the way. If the flicker stops by opening it a certain distance, it is the display inverter. If the flicker still exists, the LCD screen should be replaced.
11.Contact the manufacturer of the computer for more information and a possible replacement inverter and LCD display. This will depend on the manufacturer and the computer itself.

I hope you find it very helpful. Thanks

My Acer Aspire one screen flicker, I am running windows xp with 1 GB ram, I try to connect a external lcd monitor, the monitor display do not flicker. It seems that if I don't use full screen, the flicker...


Please check the refresh rate of the display. If it is more than 60Mhz, it could cause your LCD to flicker.

Go to your display options and adjust the refresh rate.

If that does not fix it, it could be a possible problem with video card.

Try updating the driver software for the integrated video card.

Good Luck Kumpadre!

Display starts out OK, but after a few minutes it begins to flicker in the upper corners, and the turns on and off a few times before staying black?! Everything else seems to function OK.... BIOS issue???...


please check the monitor or LCD that you have. because the computer will not flicker if there is a problem on the display. isolate it. use other monitor or LCD then check if it flickers again.

Screen flickers with lines but when i move the screen it stops


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

Dell monitor is flickering


If you have another computer, try hooking to it and see if it flickers on it too.
If you hit Ctl-Alt-Delete and choose Task Manager, does the box flicker there?.
Adjust the monitor ratio in the Display Settings/Display/ Display Adapter Properties, Monitor Tab, see drop down (increase screen refresh ratio to higher number).
