I have a LCD monitor, Acer AL1916W. I can remember when I bought it. But I do believe it is more than six years. I have two more monitor. One is Acer 1716B in early 2006, and Acer X223W in April 2009. So I got Acer AL1916W between 2006 and 2009. These three monitors are working well for so many years.
Until last month, AL1916W has a problem. when press the power button of it, it shows ACER logo and display the Windows screen if PC is on. Just a few seconds, less than 20 seconds, it is black. The power button is green. I know the display signal is received by monitor, otherwise the button should be orange.
And at the same time I check the problem on Google. A lot of results go to backlit issue. Some are very clearly pointing to the failed capacitors.
If I replace it by a new one, I may need to pay about $150 to get a 19 inch LED backlit monitor from different brands. To repair it by myself, it may cost me less than 10 dollors.
OK, let me start it.

Sometimes, we have to test our monitor, or LCD. This software, Monitors Matter CheckScreen can be used to test both of them.
Monitors Matter CheckScreen V1.2 is a professional test software.
This is one of the best programs intended to test your monitor! It will allow to properly adjust the monitor before testing. Then you will be able to perform the following tests: colour, focus, geometry, power supply, streaking. CheckScreen has a separate tab for LCD testing, which contains the following additional tests: crosstalk, smearing, pixel check, tracking!
Let’s look at the main screen of it.

Resolution Guide for Monitors, Laptops, Televisions and Projectors
You’ve seen the confusing alphabet soup of acronyms describing the various resolutions for monitors, laptop displays, LCD and plasma televisions, as well as projectors, yet you probably still don’t know what it all means. Click on this hyperlink for an article that explains resolution and includes charts that match the alphabet with the numbers.
Resolution – What is it?
What Are Common Resolutions for Plasmas, Monitors, Notebooks, and Projectors?
Briefly stated, sharpness and clarity of the picture on screen is determined by its resolution, which is the sharpness of the image projected based on the number of pixels. Resolution is measured in the number of pixels horizontally multiplied by the number of pixels vertically. The higher number of pixels, the better. Plasma screens, projectors and LCD screens have a fixed number of pixels, referred to as the “native resolution,” or the resolution at which the display device does not have to expand or compress the input signal. This is the device’s optimum resolution. LCD images used in front projectors and rear-projection monitors typically offer XGA (1024 x 1024 x 768 pixels) or SXGA (1280 x 1024 pixels) resolution. Front projection monitors also use SVGA (800 x 600 pixels).

The Truth About Response Time
In our continuing effort to provide up-to-the-minute information to consumers, our editors wish to shed light on the multitude of numbers (or specifications) that accompany advertisements, brochures, user manuals, etc. regarding LCD monitors. Amid the cacophony of digits large and small appears one expression that is particularly important, but often overlooked. This mysterious number represents image response time and is articulated in terms milliseconds (ms), such as 12ms, 16ms, 24ms and so on. Response time is the screen’s signal reaction speed, or the time it takes for a liquid crystal panel to go from total white to total black and then back again. A 16ms LCD monitor corresponds to 63 images per second, while 12ms is equivalent to 83 images a second.

The world market for flat panel displays exploded to nearly $38-billion last year with projections of 18-percent growth for each of the next three years. According to the October 1, 2003 issue of Business Economics magazine, few – if any – markets this size are growing at such high and sustained rates. The reasons are obvious. Flat panel monitors employ TFT (Thin Film Transistors) technology that creates gorgeous images. And the attractive, thin-bezel design has captured the imagination of everyone who values style and substance. Consequently, virtually everyone is abandoning their CRT monitors and racing to buy flat panels – and prices are dropping fast. To help you decide which sleek, ultra stylish flat panel monitor fits your needs, our editors have compiled this handy (it’s even easier than plug and play!) LCD flat panel buying guide.
