Question about Dell Inspiron 1521 Notebook

Right half of Inspiron 1521's screen is dark

The right half of my Inspiron 1521's display is noticeably darker than the left half, as if the backlight is failing on one side only. What could be causing this and how can it be fixed?

They there, it could already be a problem with the LCD if you stil have warranty call dell at 1 800 822 8965 - or try this hold down Fn then press the power button it will run diagnostics on your pc. if its still the same under diagnostics then it only means your LCD needs to be replaced.

if this helps please rate..

thanks

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

Dull laptop screen back light


You may have a faulty CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Screen Half darker


It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.

Toshiba 57LX177: Right side of screen darker than left


I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.

Hp dv6149us right half of LCD is dark, left half is OK


Sorry to say, I had a similar problem except my screen was upper/lower not left/right. If the drivers and hardware appear fine then it is the screen or connection to the screen. If under warranty send it in now! If not you may need to buy a replacement screen. Shop around for prices AND other solutions- (not being there to give it hands-on care) I may be mistaken.
