Question about Acer H243H Monitor
I just unplugged the DVI cable and plugged it right back in, now monitor says No Signal. Worked yesterday...
If your monitor has various input sources, make sure it's on the correct input source in the main/input menu. If that's not the problem double check the cable for bent pins also make sure if you have a video card with DUAL dvi outputs that your using the correct one.. as the other one might be secondary and non-functional. It's possible but highly unlikely if you unplugged the DVI cable while the monitored was still powered on it could have damaged the video card of the computer or mainboard of the LCD monitor. When in doubt try another DVI cable if all else fails.. if you have another DVI monitor (thats a known good) try that also to make sure that the video card is not the problem.

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.
For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.
The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).
If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

SOURCE: Acer AL1916W 19" problem
Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

sounds like a video card issue. Check the screen on another computer. If it is doing the same thing, it is the monitor. If it doesn't, then you have a video card issue

I have a dual monitor system, both are the x223w. Same problem but only on the second monitor. Backlight shuts off.On/off light stays blue. I have to turn off the monitor and turn it back on. I returned it and Acer could not find any problem so I got it back. No problem for awhile and now a few times over the past couple days. Not good...
