Re: Brightness fades

This is a Common problem MOST if NOT ALL, problems like this with this type of fault it is invairably a problem with the Power Supply, in the PSU Electrolytic capacitors dry out and often cause this type of exact problem... It is a relitively simple fix, by replacing the caps with new ones... Any good shop should be able to fix for a modest fee.. OR if ya know anyone handy with a soldering iron maybe they could do it for you there are generally about 4 - 6 to replace... in the PS section, just do them all to be safe..

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!

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.

On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.

most monitors get darker with age -- for a while you can counter this by turning up the Brightness and Contrast controls, but this only gives you a little extra time (and probably speeds up the decay process anyway).

Display problem

the adjustment box for colour, brightness and contrast stays fixed on the screen. i tried pressing the exit button.... after a few times it disappears only to reappear within a few minutes. also the auto adjustment option, for which we are supposed to manually press the i button, keeps auto adjusting the screen whenever it feels like it. the box appears right in middle of the screen and is a real nuisance as it blocks out the main portion.
