Your problem is caused by a failure of the filter capacitors in the power supply board, this is a common issue on LCD monitors. Here is a link to repair information for this model. You can repair the monitor by replacing the filter capacitors.

SOURCE: Hello, my Dell E173FP 17"

It has shorted out transistors in the inverter circuits, check them out first, also check the fuse in the inverters section.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: My Dell Monitor E198FPf didn't

I was given the same monitor by a friend which was displaying the same symptoms, upon disassembling the case and examining the power board (the larger of the 2 boards inside the case) it was apparent that the problem was 2 defective capacitors located on the upper right hand corner of the board (a capacitor is the barrel shaped components that have an X indentation in the top of them), when these components fail they swell and the X indentation will split allowing the internal pressure to be released safely. specifically it was theC862 cap which is a 25V 1000uF & the C869 cap which is a 25V 470uF. Both components cost less than $1.00 each and after replacement the monitor is working fine.

i believe you may have answered your own question here because what you are stating is a malfunctioned monitor if you plugged other monitors to the cpu and they worked and the monitor in question is not working maybe it was a storm surge and since it did not have a surge protector then maybe the monitor is shot and you may need to replace the monitor...

Dell monitor e17s fbp.. wont turn on


Flashing power LED light means you may have shorted (Emitter to Collector) out transistors (c5707) or bad fuse (fuse has high resistance) PF751. Those are what you need to check. see pictures here: http://s807.photobucket.com/albums/yy352/budm/Dell%20E173FPb/

Dell flat panel monitor -power button blinks green to amber - no


One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.

what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.
