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

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

Thanks for the awesome explaination

The answer is that there are several causes of a dim display or the failure of a backlight to illuminate the screen. As most people are aware, inverter and backlight failure are the most common. Other causes are:- a faulty or damaged LCD/Inverter cable, Faulty motherboard and a faulty screen.
Firstly try the obvious!
There is a little switch usually located near the hinge which switches the display off when the lid is closed. This can sometimes get jammed and is easily overlooked. It might simply be a question of unjammimg it or making some sort of repair to it.
Most laptops are able to toggle between an external display and the built in screen. Sometimes the laptop can get confused so it is worth toggling between external and built in screen. As most have several different settings it is worth doing this several times. If the laptop screen flashes when you do this it would indicate that the inverter is trying to start the backlight. This means that there is a good chance that either the backlight or inverter has failed but does not totally rule out the other components.
It may also be worth resetting the bios as these settings can sometimes be lost especially if the cmos battery is on its way out or has been disturbed.

Hp Laptop screen flicker


I am sure that the issue is related to the cable that connects to the LCD Display or the LCD Backlight.
There should be some connection shortage because of which the LCD flickers few times as stated by dan231.
I Recommend you to get the Notebook examined as soon as possible before something really goes wrong...

The laptop screen


This is going to be a hardware issue. Start by checking the screen connections, they sometimes work loose. If the connections are good and the problem persists, it's going to be the inverter or screen, and unfortunately, replacement is your only option.

The screen flickers, have to reboot it


Start by checking Dell's support site for updated video drivers, then uninstall the drivers for the screen from the device manager, then reboot. It will find and reinstall them. If this doesn't cure it, then this is going to be a hardware issue. Start by checking the screen connections, they sometimes work loose. If the connections are good and the problem persists, it's going to be the inverter or screen, and unfortunately, replacement is your only option.
