You may have a 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.

    The problem appears to be a backlight problem, It still be an inverter problem, it may not be able to supply enough voltage at a high brightness setting or it could be a faulty CCFL lamp.

    A new inverter id approx. $40 and is easy to swap out, I would try this first. The CCFL lamp is approx. $10 but it is more work to replace.

Dell Inspirion 546 screen keeps going black


It sounds like a hardware fault, does it happen when the laptop is cold or does it start to go faulty after its been on a while, if it goes faulty after its been on a while, its more than likely that the fan cooler is all blocked up with dust, and will need to be cleaned. Hope this helps.

guess there is an larger issue with your notebook.....
you need to get the backlite changed, if you have chanaged the lite then there is a compatibility issue with the screen and the invertor board that's behind the LCD screen.
or the system is not supplying the correct current to the backlite / invertor board

a HW tech guy may solve your issue

Screen goes blank after 2 seconds


hold a bright flash light to the screen after it goes black if you can see the words through the glass ... That means the back light is bad...or the power supply feeding it. it will be cheaper to buy a new one. if thats the problem.

The inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. The inverter board converts low voltage DC power (few volts) supplied by the motherboard to high voltage AC power (few hundred volts) needed for the backlight lamp.
When the inverter board works properly, the backlight lamp gets power and the LCD screen lights up. As a result, the image on the screen is bright. If the screen is dimming down, means that the inverter is failing in it;s job to supply the needed voltage to the Backlight.
The Inverter is mounted underneath the display screen and is connected by a two wire plug.

Black Screen at full brightness


It sounds like your backlight or inverter is failing, and soon you won't be able to see a picture on any setting. This is common for LCD screens over time, they start out with the occasional blackout and then progressively get worse. You can take it to be repaired, but the cost severely outweighs the cost of purchasing a new laptop.

L13V36 Dark Screen, picture can be seen in bright light.


If the backlight lights up for a second it's probably fine - It lay odds on the display inverter in the screen. Actually finding parts for anything made by gateway may be difficult, however. They do not sell spare parts. Considering the size of the LCD i bet it would almost exceed the replacement cost of the screen to repair it
