I would try an auto-adjust first see if that helps any, also you could try it on another PC to make sure its not your video card on your PC. Another option is to reset the screen to its factory defaults see if that does anything.

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!

I have an lg monitor flatron w2453v, right now it works great but the screen is split, what i mean is half of it is good the other side is a hint darker, how do i fix this?


Hi, Usually what it means when a screen is darker on one side than the other is that the " backlight " has becom weak. You can try turning the overall " Brightness " down and this may lessen the problem a little. In my opinion that's what should be causing the problem. Good luck, I hope this helps, Prodzilla.

Samsung LCD 46 inch half of the screen is darker than the other half.


Hi, while fixing another persons lcd tv i used lower rated power supply to try to fire up the tv ( picture-no sound) the bulbs ( actually cold cathode fluorescent ) lit up but only halfway. So sounds like the power supply for your backlight has gotten weak. You may try a workaround I've used on personal equipment, try turning down brightness on tv-this may,if your lucky, even out the brightness. hope this helped. Prodzilla

I'm tring to restore original settings on my LG monitor and keep getting "osd lock" message. Half my monitor is very bright, the other half it 10-15 shades darker.


I held the "Menu" button down for 15 sec. and it unlocked. Then used the Auto Set feature. It didn't work immediately on the two-towned
screen, but corrected itself within 1/2 hr.

Thank you.

Upper half of screen is darker than the lower half


Hi,
Its back light in LCD Panel problem, there are approx 20 CCFLs in 40" lcd panel and one or two in upper half is not providing enough light to give proper brightness so you see bit darker image.
As per Sony policy, lcd panel will be replaced to fix this issue and local tech can fix it on component level (replacing bad ccfl) if he/she agrees because its risky work.
Hope this nfo will help you.

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.

Shows half screen only!


if you can't expand your screen size from the pulldown menu or vertically or horizontally center the picture one or two of the centering coils could be partially burned out. the monitor uses electromagnets around the crt neck to center the picture. varying the center controls apply or take away voltage from the coils to center the image. may be time for a new monitor

The bottom of the screen has become darker!


Hi
The symptom you are telling is similar to FL inverter problem but with that case usually entire screen goes dim. You may try to reset the settings (Usually AUTO button). Unplug and plug in the electrical connection+Computer connection. Also make sure your Display setting in computer side has not been modified. If issue persist take to the qualified service center. FL inverter is the illuminator part of LCD works like fluorescent tube. FL inverter issue rather lower cost compare to other LCD issues.
Good Luck Happy New Year
