Samsung laptop keeps freezing and flickering


Freezing is probably caused by a virus or infection.

Try booting into safe mode, then download and install MalwareBytes and run a quick scan.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Open your internet browser then download and install MalwareBytes and run a Quick Scan.



Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.

If you are talking about your screen flickering, the lcd screen might be going bad.


Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the video shows on the external monitor without flickering that proves your video card is ok, ,but your lcd screen is bad. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.


If the external monitor flickers like your lcd screen then the video card inside the computer is bad.

I get an intermittent shadow on the left-side of myscreen. Computer works fine, except at times I have the shadow.


If you mean that the left side of the screen goes darker than the right side, then this is an indication of a faulty backlight. There are probably two CCFL tubes, one on each side of the screen. If one starts to fail, then that side of the screen will get less light and look darker. The tube may need to be replaced.

The screen on my Toshiba Tecra laptop has been flickering the past couple of weeks. Today, after using for about 5 minutes, the screen went completely black. I had to reboot to get the screen lit again. ...


Sounds like an inverter problem. If your laptop is still under warranty, send it in for repair. If not, and you know a little something about taking laptops apart, then you can take the screen a part and see the inverter behind the screen. It is long and skinny and has wires coming out of both ends, one side going to bulb, the other to the motherboard. Inverters are fairly cheap, and easy to replace... it's getting to it that is a pain.

The screen has just started to play up, 1st it started to flicker, then gradually it gets darker until eventually you cant see anything.


Please have the lcd screen checked because there could be a possible problem on the screen already or possibly the connector inside the laptop for the screen.

ASUS eee701 - Display is flickering in black/white version


If the entire display is flickering, tha'ts typically a hardware issue. Try tilting the screen back and forth, or pressing gently on the area just above the keyboard to see if you can replicate the issue. If it flickers then, you've got a bad cable or a plug.

It's unlikely, but if it is a software issue you can try dowloading new drivers for the video card. Go to the ASUS website, enter in your model information, and see if you can find drivers for the video component.

The screen on my dell inspiron 1545 64 bit windows vista is darker on one side than the other and sometimes flickers and progressively gets darker, could it be a driver? or something that i can fix online...


The CCFL [cold cathode Fluorescent] bulb is dying. Manufacturers use these thin 'tube' style lights at the edges of your display for laptops and LCD monitors & TVs. Don't let it go too long or you will possibly destroy the inverter that provides the power to light the bulb.

The screen one one side gets darker then flickers


Hi,

The problems you are describing lead me to believe that the backlight on your monitor is dying. If this is the case you have two options.

1. You can try to repair it yourself, which can be very, very difficult.

or

2. You can take it somewhere (like Best Buy) where they'll replace the screen for you.

The downside to # 2 is that it's quite expensive indeed.

Hope this helped :)

Screen is half dark and whistles when battery is unplugged


You could have a defective screen, either a faulty inverteror a CCFL lamp - follow this to determine the fault.

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.
  • 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 it up, 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.
