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. Basic LCD monitor troubleshooting guide:
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

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.
