You may have to open it up and look for bad soderling works, see my pictures to see what bad solderign joints look like. Also check fuses, connectors, etc.

The moniter went all black and the power button on the moniter is flashing on and off

Please disconnect the monitor from the PC and if still the monitor is blank then monitor is defective because when you disconnect the monitor from the pc you should see a message on the screen about signal like no signal etc..

This issue could be either the Monitor inverter failing or it could be your Video card. If you have another computer available, plug the monitor into a different computer and see if you get the same behavior, if you do, then the monitor is failing and needs to be replaced. If on a different computer it works fine, then you may have a video card failing. Does it seem to happen the longer the monitor is on? Could be as it heats up, it starts to fail.

Blank monitor

Luckily I'm not in it for the money so here's your answer. (Sorry drumbanger.)
When it goes black, look at your power button. Is it still green? If so, the backlight display is bad. If the power light has turned orange, you're most likely looking at a power/inverter problem. Sadly, if you don't have another monitor that you can swap parts out with, you're looking at a new monitor. But with the economy on the downslide, replacements keep getting cheaper! Research online and you'll find some fantastic deals! Rate me if you find this helpful.

Dell 2407 a04 Turns on (for 2 seconds) then off

your pc may be set to a resolution that is out of range for the monitor. Boot into "Safe mode" reset the Display settings to 640 x 480. reboot into normal mode then change the screen settings to your desired resolution.
