Try disconnecting the video source; most monitors will inform you of the missing signal by putting a warning box on the screen if they are functional. Before ditching it, I would try connecting the monitor to another computer or borrowing a monitor to make sure your internal video source is working.

Asus Monitor


Here are a few possible problems with your monitor
1, Backlight gone bad
2. Power Supply gone bad
3. Wrong display resolution
Given that your monitor is only 14 months old, I would lean toward
either a bad capacitor in the power supply or the screen resolution
needs to be changed (boot up in safe mode and change the resolution)
The power supply problem would require some dis-assembly and working with high voltage.Not for the faint of heart..

Monitor Screen goes black every few seconds!


Check the capacitors on your monitors circuit board. If they have opened up at the top, they are fried. Buy new ones, make sure nothing has leaked from the old ones, and replace them.

I need help fixing this problem, please


Common problem with this model is bad solder connections on the coils in the power supply. With good eyes or (for me) a magnifying glass, looking at the bottom of the circuit board will reveal the culprit.
Easy fix.

Screen going black, green LED staying on


Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed.
Easy Fix REALLY EASY FIX
(inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)

Check some of the other posts as it is probably just a bad capacitor or two and very easy to fix if you can do that sort of thing. I did and mine is back up and running.
