If I had your laptop model I could point you to the exact part. It is a bad LCD inverter. It is a small tube shaped circuit board located under the LCD screen behind the screen bezel. One end connects to the LCD data cable, and the other end has a 2 pin connector that goes to the LCD backlight bulb. The part is usually about $10-15 and is relatively easy to replace yourself. Remove the screws on the bottom of the screen bezel and carefully pull the bezel out toward you. You will see the inverter there. Unplug both ends, replace with the new one and re-assemble. when i  starts - cheifhoho.jpg

Sounds like the backlight inverter is shot. The inverter is a high-voltage power supply that runs the fluorescent backlight bulb(s) behind the screen. If you can see the screen in bright light or with a flashlight the core laptop is okay. Also you can connect an external monitor and use it this way.

Laptop is on but screen is black


Try an external screen. That will exclude the motherboard. Shine a bright light at the screen, if you can see a picture, the back light has failed.

Toshiba Equium A300D - 13X laptop black screen.


Hi. try accessing the Start-up BIOS features by pressing F2 or Delete key when you see the Toshiba logo. Check for the Tab that will give you the control for the brightness/contrast of the screen. If that doesn't do anything then most probably the backlight (LED or CFL) must have been busted. and needs replacement.

My hitachi 15.4 inch laptop monitor is not working, i can read and see everything but its very dark so what is the problem and how can i read it clearly?


Hi:
You should first try to increase the screen brightness by holding down your function key and hitting the screen brightness key. If you have tried that, borrow a computer monitor, and connect it up to the VGA output connector on your laptop. If you toggle to an external monitor, by holding the function key, then the monitor key, you should be able to tell if the video is bright on the external monitor. If it is ok, then your laptop has either a bad LCD inverter, or backlight bulb.

Low brightness


that would probably be a failure with the lcd inverter other symptoms would include redness of the screen and sudden black-outs.

Loss of light on screen Dell Inspiron E1705


Hmm, this could be a problem with the backlight inverter or something as simple as power settings.

In power settings from control panel there should be an option to alter the brightness lever of the screen when on battery.

Have a look in there and set it to default to see if it makes any difference.

Let me know if you need any more help.

Regards

Mac laptop displays minimum brightness


Check to see if there is a box right below that... Saying something along the lines of readjust to brightness of surroundings, etc!  Make sure box is unchecked for you, in regrds to your issue and then see if that helps!  I will look a little further into it for you!  Let me know if that helps though!
