Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

Screen won't turn on


You can try to do the monitor self test.
Monitor Self Test:
1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD.
It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.

Tip

Applying the settings to the logon desktop


Next, you need to apply the Screensaver settings to the Logon Desktop / Welcome Screen (Technically, HKEY_USERS\.Default registry key), so that the Screensaver is invoked when no user is logged on. Copying all the Screensaver settings to the Logon Desktop (or Welcome Screen) manually is a tough task. Use Tweak UI instead.
Download and install TweakUI.
Launch TweakUI and click Logon, click Settings.
Select Screensaver from the list box and choose Copy Now
The Screensaver settings are applied to the Logon Desktop
Restart Windows for the changes to take effect
Allow few minutes at the Logon screen, to test if the Screensaver is working properly. The Screensaver should launch after the timeout. It will look as if the Company Logo moves around.
Additional Tip
The User interface / slider allows the minimum value for picture change interval to 6 seconds only. To reduce the change interval to less than 6 seconds, alter the registry value named ChangeInterval (Set decimal value 1000 for 1 Second, and so forth) in this key:
HKEY_USERS \ .DEFAULT \ Control Panel \ Screen Saver.Slideshow
For Current user profile, make the change here:
HKEY_CURRENT_USER \ Control Panel \ Screen Saver.Slideshow

With no logon wallpaper set, Windows displays a pre-defined color for the logon desktop. ( If you have enabled Welcome Screen, press CTRL+ALT+DEL twice to see the logon screen background color. ) To change the logon background color to that of your choice, you need to alter the registry:
Click Start, Run and type REGEDIT and press Enter
Navigate to the following key:
HKEY_USERS\.DEFAULT\Control Panel\Colors
Backup the registry key by exporting to a REG file
In the right pane, double-click Background
In the Edit String dialog box, type the Color code in R G B format and then click OK.
Example: Type 0 0 0 if you want to see a Black background. You can choose any combination from 0-255
Points to ponder
If the logon Wallpaper is set, the background Color may not be visible. So, you must reset the Wallpaper value to a blank string in this key: HKEY_USERS\.DEFAULT\Control Panel\Desktop
If the Background value is set under the following Winlogon registry key, the above setting is ignored. In other words, the Winlogon\Background value takes precedence over the .DEFAULT..\Background value.
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

LCD Monitor Blank/Non-Responsive - Dell E173FPC


Next thing I would check is the VGA cable between PC and monitor.

Make sure is in at both ends and if possible try another one.

Do the Dell Menus come up with no VGA cable plugged in? Is the light amber? Flashing or static?

Screen goes dim under different user


could be an issue of his resolution and refresh rate settings are close to being out of range for the monitor. Try lowering these settings to get better performance.
