I have had the monitor for several years with no problems then all of a sudden when I turn the screen on, I see whatever is the input for a flash of a second then... blank. Its almost as if it just has power for a second. The little green light for the button stays green. I'm not sure if its something serious.

Re: monitor powers briefly then goes blank
Sounds like a Control board issue or a Power board issue... Might be blown Capacitors, in which case there is not enough power being supplied. Check to see if there are cheap parts on Ebay as replacements. If you don't want to go through the trouble sell the LCD itself for $150-250.

It doesnt sound like a windows problem. A simple test for this is to unplug the vga or hdmi cable from the monitor then turn it on if it has power it should say no signal. Also try either another power cable to the monitor or change the fuse. Hope this helps.
If you turn the monitor off then about 1020 sec turn it back on and have
a picture for five sec again it sound like the power supply in the
monitor. but if that did not solve the problem, the
picture board on your monitor is bad, since it goes off after few
seconds and the power led or button is on, it means the
board of your monitor has developed fault and will need to be replace.
advice you replace the picture board on the screen of your monitor to
solve the problem of the blank screen.
I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.
Hi this is the way how to examine what's wrong with your LCD
monitors. Power on both CPU and monitor. After going blank, you
check that you can see the image on the screen by shining a flashlight into the
screen, not directly but find the best angle to the screen and take a look very
closely. If you can see the icons or any image, there will be a minor problem.
Like me, I can see window image using flashlight and check lamps inside. Some
of them were broken and it is easily replaced. If you cannot see anything on
the screen, there'll be some problems with inverter board. If you have
soldering tool and want to fix it by yourself, check the caps first. It may
cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
