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.

How do you fix a black and white wii screen


What exactly is the screen doing? Is it black? Is it smearing? Is it showing only some letters and then very smudged and very dark letters?

Since it is likely that the screen you are talking about is an LCD or LED device, it is a sandwich device that is made up of various layers of electrically conductive material. The letters are formed via impulses that come to the back of the device and which then light up certain points while leaving others dark. The result is the display.

If the display is smearing, then it is likely that the conductive gel is leaking a bit within its cell-like space or it is likely that the rear electrical contact pad has been damaged, perhaps by an overvoltage condition. In this case, there's not much that you can do, other than replace the device, if that is at all possible (some devices are integrated into the device itself and the only way to repair it is to replace the entire device -- plug-out-plug in).

If the device is black, then it indicates the it is gone and has to be replaced. The same is true only if some segments are showing while others are not.

Let me know if this helps.

The screen is really dark


Locate the Fn (Function) key on your keyboard. It may be on the bottom left side with dark blue letters. Locate the two "brightness" keys near the top of the keyboard. These will be in the "F" keys, possibly if F6 and F7. They should have little sun pictures or something similar to indicate brightness. Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness. Tap F7 repeatedly until you reach the desired brightness. Fn must be held down as you continue to tap. Hope this helps.

The problem is with the backlighting CCFL tubes, they aren't powered. Take the screen apart and check them - if the tubes are ok then verify the inverters that is powering them.

When the screen is dark there are lines that run back and forth across the screen which is only noticable when pitcure is dark immage.


the screen bias needs to be turned down-ehind the front cover which is behind the grille there is a small black square about 3 inch square 6 little knobs sticking out 3 say in small letters screen and 3 say focus, don't adjust the focus just the screen for the coresponding color that shows up when picture is dark.best way to do this is darken the room and put it on video input with no signal if lines are white slowly
adjust 1 color after the other counterclockwise untill
lines disappear if only 1 color shows then only adjust the knob with the matching color. this is a very fine adjustment, to much will make your auto focus stop working. check it after you are done

My screen went dark suddenly, when I try to restart my computer the screen is tinted red before going dark again. The screen is not completely black as there is letter visible underneath.


From what you are describing, it sounds like the inverter board is failing. This board sits under the LCD screen and is responsible for taking the DC voltage from the battery and AC adapter and converting that voltage to high voltage AC power for the backlight lamp that sits inside the lcd screen. Without that high voltage the screen goes dark. Most inverters do not fail right away, there are voltage fall offs etc. Inverters are approx. 15-20 bucks on ebay, for most laptops, they can be changed out simply by removing the bezel around the screen, unplugging the two connectors on the inverter and changing it out. In most cases except Dell, the inverter is just sitting in there and is not held in by screws.

A dark screen might be the result of a poorly adjusted display contrast. This can be altered by accessing the Setup menu and selecting Display.
