The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp.
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. Please click on this link and follow my instructions to identify the fault and possible fix :-

Hi there! Try this trick...

You can adjust the screen brightness within BIOS set up...

It works with Dell!!!

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.

there is a invertor in LCD. it makes your lcd bright white shine. if it doesnt work you can have dark view. i mean something going on the lcd but you cant see clearly. take to tecnic service your computer.

i hope it works.

Try to load to safemode by restarting the pc and hitting F8 before loading the windows, after you load to safemode right click on desktop screen and hit properties and check if you change the size of screen?or the setting there? also look for the device manager of your vedio card and check if it works properly.
If all this not working this means your vga converter has problem this is card inside your laptop mostly happen with dell laptops, if you donot want to change it now, try to see if you have external screen port and connect your laptop to external screen.
Let me know wat happen?

Best Regards

Hi Yacob

First Run a diags on the dell laptop. You can initiate it by pressing fn+power button together and start the laptop. It will go to the diags screen. Tell me if the diags pass or not and then we will troubleshoot further.

It sounds like a LCD backlight problem. Bring it to an authorized repair shop.

this is a problem with windows you will need to reinstall you will either need to use the cd that came with your laptop (if one was included) or using the recovery partition. You can learn how to use the dell recovery partition in your user manual.

1. The problem could be the power output of the adapter. Computers are so much sensitive to power output.
2.The problem could also be wrong fusing or no fuses at all or the fuse isn't working.
