Look at the screen closely, if you can see a little bit of the image but only very faintly, there is a possibility it is your backlight because the laptop is probably older than 3 years. If that is case you have to replace the ccfl bulb of the screen. It is a relatively difficult repair but it can be done, if you look for guides to replace the LCD backlight online you will find something. I work for company that does Laptop repair in NYC and we do this repair frequently. Be sure to get the exact ccfl lamp for your screen type on ebay, it's all about the right length of the bulb.

You'll have to check a few areas:

1. if u left it plugged in while u were gone anything could've happened.
2. ensure that the laptop is not operating on battery power only.
3. make sure your adapter is working properly, try to plug it up to another laptop, or check the LED light to see if it's operational.
4. ensure that the surge protector u have in the wall is not shorted, there are some models that will also tell u if the wiring within the wall is good or not because that could be shorted as well.
5. plug the laptop into a different outlet in the house.
You could have possible internal damage to the laptop...try system restore...if none of that works, if its still under warranty backup all your info to an external harddrive and send it in for repair.

My acer aspire 5313 works when connected to externel screen and has a dim screen when using the screen. i have changed the screen, inverter, and signal cables but still same problem. i looks like the...


Hi Daniel,
The LCD screen displays is dark/ dim because there is no backlight.
There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. But most likely it is the CCFL (Lamp). Its life is limited and depending upon how long it has been in use, you can have a better idea - if its the CCFL or Inverter.
(Rest assure that your system/ motherboard is ok as you have checked it by connecting you laptop with some external display, which is working fine). Hence, the board/ graphics processor is OK. (In case the graphics processor fails, there is no display at all on the external monitor)
So, my advice is that you check the laptop LCD display for replacement of CCFL. I have found a general link about CCFL replacement. Click here for detailed and graphical DIY instructions about LCD disassembly.
Make sure you take proper precaution while working inside LCD, as the inverter generates a very high voltage.

Hope it helps! Good Luck!

Screen turns blank all of sudden and works normal after switching of the system for 1 hr or so.


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

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 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.

Laptop screen is totally blank as a duster with magnet was used to wipe the screen by erros


It is highly unlikely that using the magnetic duster could damage a LCD screen except putting scratches on the surface of the screen. There is nothing in a LCD screen that can be affected by a magnet. A magnet will affect a CRT monitor because a magnetic field will affect/deflect the electronic beams that hit the color phoaphorus dots on the screen.

My laptop screen not working it is dark?


Most laptops dim when you unplug A/C power from them, there are also usually software switches or keystrokes you can press to change the brightness. Usually 'Fn' key plus another key on the keyboard indicated by a sun with an up or down arrow. If none of these apply then it becomes a possible hardware problem.

This is because your screen is not compatible with any resoultion past 1280 x 1024. Look at your screen's specifications here: http://downloadcenter.samsung.com/content/UM/200602/20060210090838125_BN59-00521A-01Eng.pdf (Page 76 listed as Maximum resolution)

If you want to go past that, you must purchase and/or use a different monitor. Just be sure to look at the Maximum Resolutions BEFORE you purchase a new monitor!
