Boot to bios and check if the lines can be seen. if the lines are visible, you have a faulty LCD. if not, update the display driver or graphics driver.

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

Monitor flickers, similar to a fluorescent light bulb that is going out. Also, there is one line on the left side of the screen, going up and down, that changes color, but it comes and goes. I thought...


The problem is in the monitor screen, there is a large circuit board connected behind the main display screen. The video signal is feed to the main board and generates the proper color balance, the second problem is the lamp behind the display is flickering and breaking down. To repair this will not be cost effective, cheaper to replace the monitor. But I would suggest hooking a spare monitor to the computer to make sure there are no additional issues.

Monitor flickering and rolling


Thanks for the git back: #1 I hooked up a second monitor (depressed fn+f5) and was able to view everything fine. No problem in any area. Ran Some security checks (malwarebytes,checked windows updates,Secunia PSI,and a virus scan. #2 I opened up the monitor and checked for possible loose connections. #3 brought up the graphics display and checked that 60 hrz was set and correct. #4 ran a backup of all my data from my other monitor,and I made the assumption that it was a bad monitor and I might save some money if I just bought a new laptop.Would like to here your comments. Sincerely : dandee4u3
