My screen keeps flickering and its only two weeks old


Step 1 Change the refresh rate to match the capabilities of your monitor. The refresh rate is a measurement of how many times the screen redraws each second. Although this setting is related to older, desktop monitors, it can affect the quality of the Liquid Crystal Displays found in laptops. Right-click the desktop and choose "Screen Resolution," then click "Advanced Settings" and "Monitor." If enabled, place a check beside "Hide Modes That This Monitor Cannot Display" and choose a higher refresh rate from the list.
Step 2
Update your graphics card drivers. This is the most likely cause if you've always had a problem with flicker. Look for "Hardware and Sound" in the Control Panel and click "Device Manager." Under "Display Adapters," you'll see the exact brand and model of your video card. Go to the manufacturer's driver Web page and search for this model to download the appropriate drivers. Alternatively, you can revert to an older driver if the flicker began immediately after an update. In this case, return to the Device Manager, right-click your adapter and then "Driver." Click "Roll Back Driver" and "Yes" to confirm.
Step 3 Turn on Vertical Sync if the flicker occurs when DirectX or OpenGL is in use, for example, while playing a PC game. Vertical Sync, or VSync, locks the refresh rate of the application to the refresh rate of the monitor. Horizontal flicker is reduced, which improves image quality. For Nvidia cards, VSync is found in "Manage 3D Settings." For Intel, look for "3D Settings" or "Asynchronous Flip." On ATI/AMD cards, turn on "Wait for Vertical Refresh."
Step 4
Lower and raise the laptop screen repeatedly to determine if the flicker is related to movement. Hardware failure is the likely cause when flicker occurs only when the laptop moves. Most likely, the screen cable is loose or damaged, but the inverter and backlight can also cause this problem. The laptop needs to be opened in order to confirm the problem, but do not attempt this unless you are familiar with PC repair and do not mind voiding the warranty. For the best results, take the laptop to a licensed technician or send it back to the manufacturer.

Dell Inspiron 4100 flickering off and on Makes it extremily hard to work with . How can I tell whether it is the display or something else?


What happens when you hook it up to a external monitor? If it works fine with a external monitor, then your laptop monitor is going bad. If it does it with an external monitor, then its more than likely an issue with your laptops video adapter.

Screen making quick flashes


This could be a LCD screen problem or a video card problem.
Connect an external monitor to your laptop, power up the monitor first then boot up your laptop. The video will automatically switch to the external monitor, then go to the Internet and see if this flicker occurs on the external monitor.
If it still flickers then the video card has a problem.
If it does not flicker the the LCD screen maybe faulty.
Get back to me with the results of these test and I can advise the nexr course of action.

T61 Screen flicker and distortion.


Sometimes if the machine overheats it can weaken the solder points on a video chip so that if you touch it or bend a bit it straightens out and works fine. You can get that repaired board can be re-soldered by a company that does that sort of thing. For around $40-$80 dollars you have to ship the board and have it done. Usually pretty fast service. or it seems that maybe you may get lucky here cable monitor could be slightly wire pinched. You will need to take Monitor and cover plate off the front of the keyboard where the power button is located and check the connection it may also just need a good cleaning or make sure it is not pinching anywhere and is straight forward. This happens sometimes with monitors for laptops the moving monitor back and forth over time can cause wear on the wiring.
I would check that first wiring then clean the connection with rubbing alcohol the kind that drys out. While you at it I would also dust it out good especially the copper tube vent ports make sure they are free of debris. If this does not solve the problem also check the lamp. Hopefully it is not the screen going bad itself. It does seem to me to be the monitor cable pinching on you or shorting check that out good. Or have a pro shop do it for you.
I hope that assisted you? John

Acer Laptop Screen Flickers & Jumps


Hello,



Please connect the laptop to an external monitor. If no flickering on monitor screen, from my previous experience, this is more likely loose connection of video cable connected to the LCD. So talk to Acer support again and require the replacement of LCD.

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.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out


If this laptop is only a few monthe old, then it should be still under warranty. I suggest you return it to the supplier for repair or replacement under warranty. If you try to repair it, most likely you wil void your warranty.

If you don't have this choice then read the following info.
You most likely have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

MY ACER LAPTOP SCREEN TURNS ON BUT THE SCREEN IS BLACK


To determine if you have a video card problem or the LCD screen is at fault.
Connect an external monitor to the video port on the laptop and boot up your laptop, if you get a display on the external monitor then your video card is OK and you have a faulty LCD.

When you power your laptop without an external monitor and have a close look at the LCD screen at and you see a slight image then the fault is with the backlighting panel. This fault could be a faulty inverter or a faulty CCFL backlight lamp.

Defective CCFL backlight may has the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
The inverter can be easily replaced so can the CCFL lamp (but requires a lot more work)

Flickering screen on startup


Sounds like hardware. Several possibilities come immediately to mind:

1) Backlight is going bad. (It's a fluorescent light).
2) Bad inverter
3) Loose or bad cable in laptop hinge

If the picture is OK using an external monitor, it's probably one of those three.

I've used these guys before for screen repair: Unknown document title.
