Faulty Laptop LCD screen


FAULTY LAPTOP LCD DISPLAY
You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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 or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My laptop acer aspireone mini laptop screen is blackout i can't get it started.


You might have a faulty Liquid Crystal Display [LCD] Panel Power Inverter. Or the LCD Panel itself might be faulty. Either can be replaced. The Inverter is relatively inexpensive, a replacement LCD Panel, a little more.

To test for a faulty screen, connect your notebook to an external Desktop Monitor, using a standard VGA Cable -> press and hold the Fn key bottom left of your keyboard -> press the Function key at the top of your keyboard with the image of the two monitors on it -> release both keys -> if the image sent to the external monitor is correct then the fault is likely to be in one of the components of the LCD Screen and you should take the notebook to a repair centre to test test and replace the faulty component(s).


If you cannot start the computer at all, but there is a constant or flashing Power Light Emitting Diode [LED] on at the front but no Hard Disk Drive [HDD] LED on, then either the battery is faulty, there is a loose Direct ()Electrical) Current [DC] Jack, the Graphical Processing Unit [GPU] chip is faulty or there is a damaged Motherboard Power Management Track.

To eliminate other possible causes of the symptoms you describe, remove the battery and connect the notebook directly to the mains electricity without a battery and then try to power the notebook up. If the notebook powers up and boots into its Operating System then the battery cells are probably depleted and cannot recharge, so the battery should be tested and, if found faulty, replaced.

If the battery is not the problem, check for a loose DC Jack. If the point where the the Power Cable connects to the notebook is loose and is either in intermittent contact or not at all in contact with its solder points on the motherboard, then power might not be reaching the motherboard. Loose DC Jacks can be re-soldered or replaced if damaged.

A loose DC Jack that is in intermittent contact with the motherboard, an electrical power surge or sudden power cut or disconnection of the power cable can damage the Power Management System of the motherboard. It is sometimes possible to repair Power Management problem afflicted notebook motherboards by replacing blown capacitors and/or bypassing burnt out or damaged circuit tracks by creating new ones. Extensive damage to a motherboard might make it uneconomical to repair. Replacement motherboards are available and could be installed but when combined with the cost of labor for the overall repair the price might be prohibitively high.

A faulty GPU can have new tracks made to it, or have a damaged chip (silicon chip) surface cleaned to restore lost graphics by two different processes, Ball Graphics Array (BGA) Reflowing or BGA Re-balling. Re-balling has the longer lasting and better success rate. When the surface of the GPU is too damaged it may not be possible to repair it.

All of these motherboard repairs require a laptop repair specialist to disassemble the notebook and test, replace or repair any faulty components. These repairs can be expensive and need to be weighed up against the current value of the notebook and the cost of a new replacement notebook.

Acer apire one everything on the screen looks like night vision


Color Depth, Hue Intensity, Contrast, Brightness etc are all controlled and controllable by the Graphics Settings.

Right click on the open desktop -> Properties/Personalize -> Settings/Display Settings -> Advanced -> Graphics Adapter -> adjust the color settings -> Apply -> OK -> restart computer -> if problem is not resolved uninstall the Video/Graphics/Display Driver from Add or Remove Programs -> Reinstall Video/Graphics/Display Driver from the Driver CD of from the Support/Download page of the Acer website (see below for the link) -> restart the computer and test again -> if this does not resolve the problem, then you may have a faulty Liquid Crystal Display (LCD) Panel Power Inverter of the LCD Panel itself might be faulty. Either can be replaced. The Inverter is relatively inexpensive, a replacement LCD Panel, a little more.

To test for a faulty screen, connect your notebook to an external Desktop Monitor, using a standard VGA Cable -> press and hold the Fn key bottom left of your keyboard -> press the Function key at the top of your keyboard with the image of the two monitors on it -> release both keys -> if the image sent to the external monitor is correctly color balanced and you have tried adjusting the Graphics Settings and reinstalling the Driver, then the fault is likely to be in one of the components of the LCD Screen and you should take the notebook to a repair centre to test test and replace the faulty component(s).

My laptop screen went very dark, I can barely make out whats on the screen but I know its working. What can I do to fix this situation on my gateway p-6860fx pc notebook?


Hi josue fernan...
You need to see if your laptop lcd screen is faulty and/or the lcd inverer is faulty.
1....Test the lcd screen:
Hook your laptop to an outside monitor and then start your laptop normally...if the picture on the external monitor is good, then your lcd screen is bad.
2....Backlight Faulty: If the monitor is still as dark like your lcd screen on the laptop then it could be the backlight that is faulty.
Please take time to rate me thumbs up

I have Acer Laptop suddenly now the screen remains blank even after switching on the laptop. Actually as I was surfing the net suddenly the screen display color changed and later I thought there is...


if you can see the start up screen in full color when it starts then the last update could have caused it,
But its more likely that the plug inside the back of the LCD has come loose and needs to be replugged back in,

Backllight turns on when starting computer and


I presume that every time you move your mouse that the backlight lights up but without video.If this is the case, you have a faulty Tcon on the LCD.
If on the other hand the backlight goes out and stays out regardless of mouse action, you have a faulty invertor circuit.

LCD INVERTER


FYI,
If your lcd is cracked, your warranty is gone. It doesn't matter if it is accident or not, because it is user fault. Unless you have 3 year total warranty from acer, they will repair it.
