I would check the caps in the power supply first, it sounds like unstable DC voltages.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

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 Dell Latitude C400 PC Notebook screen flickers very fast, any ideas? thanks


It can depend on what kind of flickering you are seeing. A very very fast one, that shows more obvious if you look to the side of your screen (instead of directly at it as normal), means your screens 'refresh rate' is most likely wrong.
That's the most likely problem you have, as the inverter will usualy only make a screen flash, not flicker, though they don't usually flash too much before the bulb or inverter can't take the strain and breaks properly.
Sometimes a screens circuit can go slightly faulty (very rare) and cause a slight change in its refresh cycle, and that can cause a high speed flickering too, usually accompanied with a very slight blurring of any images.
The standard setting for a C400 is 1024 x 768 resolution at 60 Hertz, so check your display properties to see that's not been accidentally changed.

New monitor flickers when hooked to computer


Hi!

There's a few usual culprits for this problem.

  1. Check the cable. Swap to a different cable if possible to rule that out.
  2. Check the refresh rate of your monitor. Most monitors have options for this via a Menu button on the screen itself.
    If you find it, change it to 60 hertz
  3. Check the refresh rate of the monitor from your operating system/video card's software.
    In Windows, right click on the desktop, click Properties, then the Settings tab, then Advanced. Change it to 60 hertz if it's anything different.
It could be faulty but hopefully not.

Couple of things there to try...let us know how you go

When I connect my screen to my Dell laptop, I dont get any image. The monitor states that the frequency is wrong.


Click with your SECOND (usually the RIGHT) mouse-button anywhere on your computer's "wallpaper".
Click Properties.
Click the Settings tab.
Change the frequency to 60 Hertz.
Click OK.

Your monitor should be able to accept a frequency of 60 Hertz.

I had that same problem with my 17 inches LCD monitor. The problem why it
does that is due to the video card having trouble to catch up with the LCD
monitor. I set the mhz on the video card to 75 hertz and the problem went
away. set your LCD monitor at 1280 x 1024 and you won't see the flickering.

Sometimes, It is the video card that is causing the problem or interference from
magnetic waves in the house.
