You need to check the voltages and components in the power supply/inverter board first. It should have 5vdc for logic and 12~16vdc for the backlight innerter circuits.
There are three version of the boards for this model.

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, 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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Backlight problems


Yes,

If the capacitors in the power supply are bulging that indicates that they have failed internally and need to be replaced. That would cause the back light inverter to shut down just like you are having.Replace the capacitors and you should be good to go.

You probably have failure in the inverter circuits due to shorted transistors, bad solder joints, bad caps. Please see my pictures here so you will know what to look for inside.

Monitor does not want to wake up. Pressing the yellow rest switch the button goes green for less that 3 seconds, then goes yellow.


try unplugging your computer and your monitor for about a minute and turn back on. Then see if it works, Good Luck ;)

Dell Monitor won't stay on


When it goes black, does the power buton stay green or is it orange? If it's orange, the power supply/inverter is your main culprit. If the power button stays green, it sounds like the backlight for the display is bad. Either way, unless you have parts for the same monitor laying around to swap out, you're due for a new monitor. The good news- with the economy in the tank, you can search online and find some reputable vendors selling nicely sized screens for less than $100! Heck, I've even seen a 22" for $129 (once but it was there).

Monitor won't turn on without help.


Do you have a second monitor or can you borrow one to check if the fault lies with the monitor or the PC?

If the monitor is at fault then there is not much you can do yourself. I suggest you contact Dell and get them to replace it under warranty. Most LCD monitors have a 3 year warrantly, at least they do in the UK.

cheers

This is normal, typically you must press the power button (on the monitor) to turn it off.
