If you don't see the Alpine logo while booting up then the florescent bulb for the LCD must be burnt.

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

Dell ADAMO 13 w/Vista 64 Random power failure...goes dead in 1 second. Battery fully charged. Happened with external power and when on battery. I have latest BIOS v6.0. I ran pre-boot diagnostics...


If the power totally fails (i.e. power is cut off, LEDs turn off, fans stop, ... etc), then this more likely to be because of a short circuit developing in a failing semiconductor component, or a power supply problem.
However, if the laptop is still running & only the display on its LCD is cut off but the laptop itself stays powered on, then your laptop might be experiencing a failing screen inverter board, a failing screen backlight lamp, or a failing LCD screen cable.

TYPICAL INVERTER FAILURE SYMPTOMS

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Monitor went dark


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 the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

HP Pavilion, Screen working, but extremely dark!


Hi,
As per your description, I find that the issue is with the LCD Backlight which is also called as LCD Inverter which lights up the LCD to show us the Display on the LCD Display.
If this Backlight is gone bad, you will be barely able to see the Display on the LCD.
Coming to the Noise you had mentioned above can be from the Cooling fans of the Notebook which will be spinning at high speed when the Notebook starts and will reduce gradually after few minutes.
I recommend you to try cleaning the Cooling fan vents using any Vacuum Cleaner or Air Blower.
I recommend you to contact any nearest HP Authorized Service Center and get the LCD Backlight replaced.
Hope this helps....

T43P LCD keeps going dark


I think you are having problem with backlight. The concept of laptop is that if there is problem with backlight then it will try to shut it down(shut the light down).If you restart your laptop ,that mean you turn the light on again...after that if its blink or something wrong then again your system will try to shut it down to prevent other part get spoil.

What you have to do is..
1.problem from backlight replace backlight
2.problem from inverter replace inverter
3.problem from motherchip...repair motherboard.
