    Do you have another monitor that you can hook up with your desktop. Just to make sure its not the graphics card on your desktop which is busted.

    Maybe it just over heated because it is working now after I unplugged it and left it for a couple of hours. Not sure what the problem might have been. I'm pretty sure that it wasn't the graphics card because the light to the power button was just flashing and it wouldn't stop unless I completely unplugged it. I could not get the monitor to power down on its own. Will appreciate any other suggestions. Thanks!

It may have shorted out transistors, cold solder joints in the inverter circuits.
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 DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

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/

Check and make sure your connections on the back of the PC are snug...and make sure you have a good connection at the back of the monitor.
Flashing light...is loss of signal.
Good Luck,

My dell 1905FP power button flashes green and will not turn off, the screen is black.


Hello,

This is a common indication of a failure in the power supply. There are parts called capacitors that are used in the filter section of the power supply, when they go out the power supply can't properly turn on so you get no picture and a flashing power light. Here is a picture of the power supply board with the problem filter capacitors circled in yellow and below the picture in a link to a repair guide with details dis-assemble and repair instruction along with parts list for the Dell 1905FP and 1907FP models.
