You my friend have a bad backlight. Inside thes LCD monitors there a little tiny flourecnet lights that help the LCD project the images so that you can see what is being displayed. Sounds like your backlight has gone bad. These can be repaired, but can be costly! These things happen often times, 90% of the time I am replacing the backlights to various monitors. Sorry, but I am certain it is your backlight!

Boots fine but screen but monitor flickers then goes black. Is it the monitor or something else?

What operating system are you usign?
Presuming it's Windows, wWhen you say "boots fine" you mean you actually reach the desktop, the "welcome" screen or the Windows startup logo?
By your description somehow I guess you have a startup problem but need some feedback about your computers status

I am in charge of a computer account here at work and have about 15 ACER 1916B monitors that are all inop...The monitors power up and show the ACER startup then show the windows startup to only go...

This problem is caused by 2 things, the computer is set to a higher resolution that the monitors can handle, so when the graphics card drivers kick in as windows boots the screen goes blank, this is normally the problem for people trying to hook there computers to normal lcd televisions not monitors, as monitors generally are able to show higher resalutions.

In your case because you are using computer monitors, the problem will be caused by the refresh rate settings on the windows, most desktop lcd monitors have a fixed refresh rate of 60hz, my guess is your computers are set as 75hz therefore as windows boots the screen goes blank because it dosent support that high a refresh rate.

To resolve this problem, just before windows boots press F8 on the keyboard, this should bring up a black command prompt screen, at the top you will see the safemood option, tab up to it and press enter, this goes to windows but dosent load any drivers including the graphics driver. Once loaded right click the mouse in the middle of the screen, and bring the display properties window up, in this window click on the settings tab, click on advanced on the bottem right of the window, this will bring up another window, click on the monitor tab, on this window you will see the screen refresh rste setting, click the small arrow and set this to 60hz and click ok, in the other window reduce the resalution down abit using the slider, click apply and close the window, then reboot the mechine as normal, the problem should now be sorted, any problems post me back. thanks and hope this helped.

This is normal. Your monitor has a VGA hook in for regular definition. What it is doing, the monitor always by default looks for the VGA hook first. On my desktop it does the same thing until it finds a signal on the DVI.

Monitor keeps stating "monitor going to sleep" now awhile after booting up. The monitor works fine with other computers and the computer in questioning when in safe mode - yet if tried to boot normally,...

This is probably a video setting issue. In Safe Mode, Windows starts with low resolution and color settings, so the monitor can display them. But when it tries to start normally, Windows is using a video setting the monitor can't handle.

Start the computer and press the F8 key three or four times when the manufacturer's logo screen appears. This should get you to the Windows startup menu screen, and you can pick the option of starting in VGA mode. This will start Windows with video settings any monitor can handle.

Once you have Windows up and running, make sure the video card and monitor types are properly set up. It would also be a good idea to download and install the latest drivers for your video card. You can usually find them at the manufacturer's website.

My monitor works for a little while, then goes black.

Your power-inverter board needs an overhaul.
Probably in need of the standard capacitor replacement.
a bulb in the screen is bad (a bad bulb will usually show symptoms)
It will flicker, or will look pinkishish for a bit or dark in the middle top or bottom of the screen.

No Display - Screen says "NOT SUPPORTED"

Turn your computer on.
When the boot screen cahnges to black start pressing F8
You should get a Windows startup screen
If you see the Windows Logo loading page, then hit the reset button and tray again.
On the Windows Start page, select Safe mode.
Press enter twice and Windows will load
Go into display properties (right click on the desktop and you will see it on the menu)
A box will pop up, select the last tab (Display Properties) there will be a slider on the left side. Move it left to around 800x600.
Select apply and then close the window.
Restart Windows normally and it should be fine.

If not, post back and we will try something else.
Hope it helps =)

On Pwr up logo appears then LCD returns to stanby Black screen

I will assume the monitor is staying on during the boot process all the way until Windows loads.
If that is the case, then...
  • Start the computer
  • wait until the initial bios/logo screens for your motherboard go away.
  • Press F8 to get the Windows recovery boot menu
  • If you see the Windows Logo you would normally see then press rest and try again.
  • In the recovery screen, select SAFE MODE
  • Boot into Windows and uninstall your video card.
  • Reboot the computer the normal way through the start menu.
  • When your PC starts back up it should then reinstall the video card, and set itself automatically back to 60khz as default.
Let me know how you go =)
