Most of the time in this situation, the problem is due to the backlight going out. However, there are some instances where the inverter cable is bad.

The backlight is the part of the LCD which illuminates the screen. Think of an LCD as having multiple layers. One layer has the image itself on a semi-transparent layer and then behind that layer rests the backlight (usually a florescent bulb) which shines through all other layers to make the image glow and illuminate.

More info can be found here:

As far as replacing the backlight, I always replace the whole LCD itself, which includes the backlight.

Otherwise, you risk ordering the backlight and finding out that it was the connection from the backlight to the LCD that was causing the problem (very possible) and then you would have to order the LCD anyway.

I have an hp pavillion dv1000 it works fine but the screen is very faint i can barely make out the icons... i tried pushing fn f7 which is supposed to make it brighter and nothing happened... any...


the backlight may be going or has gone out, is it plugged in or running on batteries? when plugged in it should be bright with a battery is usually dies down so as not to use alot of energy.

If that does not help, try function key and making it darker, I know that sounds weird but sometimes it gets stuck in a weird loop, My dell laptop does it all the time.

My HP Pavillion DV6000 laptop starts up fine and after a few minutes the screen turns black. I can still see the desktop image in the background but barely. If I reboot the screen looks normal again but...


That means your backlight is going out. The fact that it's happening intermittently like that suggests that you have a faulty screen inverter (a small circuit behind the screen that converts DC power to AC, in order to light the florescent backlight).
I suggest replacing it. Here are some on abay for pretty cheap:

Dell inspiron 5150 dark screen, faint image in background


If it showed a pinkish tint on the screen before it went out it could be the backlite. If you can see a faint screen when you turn the room lights out it chuld be the inverter. Inverters are cheap ... a used one for around $8 on ebay. Try that first. Make sure that you buy the EXACT model that is presently in your laptop.

Screen dim to black


This will be a problem with either the screen inverter or screen backlight. You will need to take it to a shop for diagnosis, in order to find out which one it is. If it turns out to be the backlight, then the entire screen will have to be replaced. They are considered a sealed unit, and the backlight can't be changed out.

Display problem


When the screen goes dark shine a flashlight in the lower right hand corner where the Start button typically is located. If you can see faint images then you have a backlight problem. If you don't see anything then try connecting a spare monitor in its place. If that works then you have some other type of problem involving your LCD monitor. In both cases unless you have the experience and tools to safely work on fairly delicate electronics this is not a repair job for the typical consumer.
