If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

SOURCE: Blue line down monitor screen of laptop

I have had the same problem

This happens from overheating or from physically abusing the screen

I have an acer, which can take a lot of punishment, but i throw it around and keep it on 24/7 until it gets so hot the plastic starts to smell and melt

Awesome computer, it still works very well for the price (500$)

It developed blue lines on the screen lately and i know from previous experience acer will replace your screen as this may be a factory problem

If you're a freak like me who runs his computer all the time though, they aren't going to listen to you for one second and you have to deal with it

A) Dont use your computer as much (that sometimes fixes it)
B) Buy a better cooling deck
C) Dont abuse the screen (any bending or even the slightest tap can kill it)
D) If the problem doesnt go away, make peace with it and get used to it
E) Replace the screen (i dont want to, so now i have kewl blue lines on my screen)

SOURCE: The screen still displays the image but the backlight if off

The problem is in fact the backlight as you are saying but i am not sure if it is the wiring to the power supply or if your backlight is just burning out. You can ask the company if you can send it in for them to look at it.

SOURCE: sony vaio vgn nr160e laptop - no display

You may have a defective CCFL backlight, it 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 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. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, 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.

Screen is black


If you plug an external monitor in and that works, shine a bright light at the laptop screen and if you see movement, the backlight has failed, if nothing the screen has failed.

I believe you have an LED screen which does not require a CCFL bulb to enable the backlight - the reason it doesn't have a place to plug in. Make sure you have ordered the correct screen. Verify exactly which type of screen you need by checking with Sony.

One thing to try is if you can, connect an external monitor to the computer. Turn it off and then back on with the external monitor on. If video on the external monitor then the problem is with the laptop monitor most likely the FL inverter or the lcd itself. If no external video, it is most likely a motherboard problem.

I have a Sony VGN-CR220E. The backlight works and the screen gets bright but the video display has nothing but lines and some color but not in any reconizable paterns. Any advice?


The LCD screen is bad, or the video cable from the motherboard to the display is loose and needs to be reseated back in place. But before we call it ! hook an external monitor to the video output at the back of the laptop, If the monitor is good it is the laptop screen, If both show the same problem it is the video graphics card that is apart of the motherboard.

VGN ns140e Screen flickers and does not show readable image, looks ok when connected to an external monitor....changed the screen already, please help. Thanks


Your Graphics Drivers could be wrong,but it sounds more like the cable for the backlight or the screen ,you wont of change the cables when you put the new screen in did you.
press the plastic around the top of the key board & under the screen untill you find the piont where it gets worse.then remove the back panel & screen surround to see which cables under their.
But for the drivers you can get them free on my web site:

Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Can't see the Image


Can you see the image on an external monitor? If so, then you need to brighten the screen using the function keys on the keyboard. Or--the backlight or inverter have gone out on you and will need to be replaced.
