Upper sise of screen flickering problem


Technology b> A laptop's display assembly consists of an LCD panel, an inverter board and a backlight lamp. The inverter board supplies power to the lamp which lights up the LCD screen as it generates images. Light from the lamp is then uniformly distributed over the panel to create images. b> Cause b> Flickering is commonly caused by a damaged or malfunctioning inverter. Because a faulty inverter is not able to supply adequate power to the backlight lamp, the screen goes dim each time the backlight loses power. In some cases, flickering may also be caused by a faulty connection between the inverter and backlight lamp. Diagnosis b> Resolving a laptop screen's flickering problem entails correctly diagnosing the problem and replacing the faulty component. You may diagnose the problem by hooking up the laptop to an external display unit, such as a projector. If the external display has the same display problem as the laptop's LCD screen, it is indicative of a motherboard or video card problem. If the external unit displays bright, crisp images, the problem is probably caused by the backlight or inverter. b> Solution b> You may repair a laptop screen's flickering problem by replacing the inverter board or backlight. Order parts from a trusted supplier and replace the component by referring to your product documentation.

Black screen delld600


Several things can cause your Dell Latittude D600 laptop's LCD screen to stop working.

Two of the most common causes relate directly to the inverter board and the backlight lamp.


The inverter board is a thin circuit board placed inside the LCD panel.

It's main function is to transfer power from the motherboard to the backlight bulb inside the LCD screen.


If the inverter board goes bad or the backlight lamp burns out, the screen will appear dim or eventually go completely black.


Turn off the laptop, unplug the power cable, close the LCD panel and place the laptop face down.

Remove the battery pack from its compartment on the bottom of the computer.


Flip the laptop back over and reopen the display panel all the way until it is in a 180-degree position.

Insert a flat head screwdriver into the right side of the keyboard bezel.


This is the plastic strip situated above the top row of keyboard keys. Carefully pry the bezel from the laptop.

Remove the two Phillips screws located above the top row of keyboard keys.


Grasp the top edge of the keyboard, tilt it upward and lay the keyboard face down on the palm rest area.

Unplug the keyboard's ribbon cable from the motherboard connector.


Carefully remove the entire keyboard from the laptop.

Disconnect the video and speaker cables extending from either side of the LCD panel to the motherboard.


Loosen the Phillips head screws on each LCD panel hinge.

Carefully lift the entire LCD panel off the laptop's base.


Relocate the panel to a flat work surface, and place the panel so the screen is facing upward.

Use a thin, flat head screwdriver to pry the rubber screw covers from the LCD panel's front plastic cover.


Remove the Phillips head screws revealed by the rubber covers.

Carefully remove the front plastic cover from the display panel.


Locate the inverter board situated below the LCD screen, inside the bottom edge of the display panel.

Disconnect the two cables from each end of the inverter.


Remove the two Phillips head screws fastening the inverter to the display panel.

Carefully lift the inverter board out of the display panel, and dispose of it.


Repeat this procedure in reverse to install the new inverter board, and reassemble the laptop.


Hope this helps

When the computer comes on it starts fading out then it goes blank


Laptop? The Inverter is going bad. (Screen Inverter)

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.

Similar to the Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
(Average Backlight is approximately half the thickness of a No.2 pencil, and 3 to 4 inches long.
There are many variations, however)

An Inverter is used to convert the electricity provided by the laptop, for the LCD screen, and Backlight.

90 percent of the time the fault is a bad Inverter.

The Inverter is usually located behind the Display Bezel in the Display Assembly, and at the middle/bottom of the LCD screen.
It is a small circuit board.

Example of a typical Inverter,

http://www.laptopparts101.com/screen-inverter-board/

[The Display Assembly consists of all the parts that make up the display.

A) LCD screen

B) Display Bezel (Thin plastic frame in front of the LCD screen, and surrounds the LCD screen)

C) Top Cover (Top plastic piece of laptop)

D) Screen frame (Metal frame that resembles a picture frame. Surrounds the LCD screen.
{The LCD screen is composed of layers. This frame keeps them in an aligned state)

E) Hinges

F) Hinge Brackets

These are a few of the Display Assembly hardware components.

What is the laptop manufacturer's name, and Model Number?
(On the bottom of the laptop is the Model Number. Sometimes referred to as Product Number. P/N)
If I knew this information I may be able to provide a link to a free Service Manual

My laptop started playing up, then i got a blue screen come up and it died. the computer now comes on but theres nothing on the screen. its a asus eee 904hd. do i need a new motherboard


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Test with an external monitor attached to the laptop. If you get display on the external monitor, then this confirms the case.
