A backlight inverter is the power supply to power the lamp or lamps in an LCD display, so when you look through the LCD there is a souce of light behind it. Kind of like holding a peice of paper up to a light and looking through it, The light from behind shines through the paper or in your case the LCD display. You would have to open up the LCD case in order to find what is usually a long thin board, similar to the one below. This may need to be replaced or you may get lucking and just be able to replace the F1 (fuse) component and fix it. (or have a techical friend do it for you)

Hello Sir, Hi, if that is the case, your inverter board is generating audible high frequency noise. the inverter board is true to produce high frequency pulse needed by the LCD, but if should not be audible. try replacing the inverter board and see if the noise will dissapper .

you can not buy a back light on its own you would have to buy a screen or an inverter its best to take it to a computer shop where they will test the screen and inverter and say what is faulty

The backlight won't turn on but occasionally will flicker.


Suggest you replace the Inverter. A Backlight goes out all at once.
90% of the time the Inverter is the hardware part at fault.

[ An LCD screen cannot produce enough light by itself.
A Backlight is used to supply the needed extra lighting.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a much smaller scale

An Inverter is used to required power for the LCD screen, and the Backlight.
Boosts power up for the LCD screen, brings it down for the Backlight.

Dell Support > Latitude D600 Notebook PC > Service Manual

http://support.dell.com/support/edocs/systems/latd600/en/sm/index.htm

Replacing an Inverter is a simple job. Replacing a Backlight is not.
The Backlight is located within the LCD screen assembly.

The metal frame of the LCD screen assembly is removed along the edge where the Backlight is located, to access replacing the Backlight.

In the above list for Service Manual, click on > Display Assembly and Display Latch.

This information shows you where the Inverter is located on a Dell Latitude D620 Notebook PC.
The Latitude D620 is part of the Latitude D600 series of Notebook PC's.

http://www.insidemylaptop.com/remove-replace-lcd-screen-dell-latitude-d620-laptop/

Just one place from a quick search, that sells Inverters for a Latitude D600 series Notebook PC,

http://www.parts-people.com/index.php?action=item&id=2895

MATCH the part number listed that they have, to the part number on your Inverter.
You have to have THE correct Inverter.

Screen is to dark. cannot see letters very well.


Suggest you press the Fn key And the key to increase brightness, first. (Should be a key that has a sun icon on it)

Barring this does not increase the visibility of your LCD screen, the I suggest the Backlight is bad, or the Inverter.

The Backlight is a type of CCFL tube (Cold Cathode Fluorescent Lamp) mounted to the LCD screen. The LCD screen needs the light given off of the Backlight.

Replacing the Backlight is a daunting task, and if done wrong, will cause possible damage to the LCD screen.

The LCD screen itself has a thin metal frame holding the components of the LCD screen together. This frame must usually be opened on the side that has the backlight, to access the backlight. The components that make up an LCD screen are fragile, and can easily be damaged.

The Inverter supplies power to the LCD screen, as well as the Backlight.
Inverters do go bad, but commonly it's the Backlight to go first.

This shows a typical Backlight replacement. It IS not an advertisement to attempt this yourself, but a reference tool for information.

D600 Latitude laptop - LCD showing ghost/dim images


Connect an external monitor to your laptop and power it up, if you seethe normal Windows images then the video card and laptop is OK and theproblem is the backlight.

If you see a very dim image or flicking image on the LCD screen it means you have a backlight problem.

Dimimage and/or dark display on the laptop's LCD screen indicates a faultyLCD backlight and it could be the inverter that supplies high voltageto the CCFL lamp or it is the CCLF lamp is nearly burnt out or burntout, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.
Thank you Sir, Have a nice day.
