Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on? If stays on, then inverter turns into protection mode because of old backlight lamps. If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.
HOw about the light on the tower? if its stedy green then the tower is ok then run a self test on monitor if it passes the monitor is also ok then unplug the power cable from the monitor and data cable also and press and hold the power button for 10 sec and then connect the monitor to the system
The monitor you have has bad components on the circuit boards inside. This is a classic problem with all LCD monitors. I rebuild them on a daily basis so I recognize the symptoms. I would suggest finding someone who can do component level repair on the circuit boards inside. I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.
i think it can be the capacitor problem, open monitor an look for swollen capacitors. if you will find them swollen or

It's turns blue to power safe mode (yellow) it's prevent futher damaged to your monitor. It's seems you got a busted backlight inverter. Need to replaced a new one...Since you only got it for a few months, send it back to Acer for a replacement of a new backlight inverter... Have a nice day!
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.
You have to
check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) 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 mine, I can see window image using flashlight and check lamps inside. Some
of them were broken and it is very easy to replace. 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. Thank you
