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.

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

Logon Change


Enable Log-On Screen


Windows, by default, is set to show the Welcome screen during startup.

To enable the log-on screen to show, go to "Start" menu and select "Control Panel".

In the control panel, click on "User Accounts".


In the "User Accounts" dialog-box, click "Change the way users log on or off" and uncheck the "Welcome Screen" option.

Click "Apply Options" to save the changes.

Change Log-On Screen Background Color


To change the log-on screen background color, go to the "Start" menu and click on "Run".

In the run dialog-box, type "mspaint" as the name of the program to "Open".


Click on "OK". In the "Paint" window that opens, select "Colors" from the main menu and click on "Edit Colors". In the "Edit Colors" dialog-box, select "Define custom colors".


Here pick the color of your choice and note down the "Red", "Green" and "Blue" values.

Write down these values somewhere.


Click "Cancel" and close the paint window without saving. Now, go to the "Start" menu, click "Run" and enter "regedit" as the name of the program to "Open".


In the registry editor, navigate to HKEY_USERS\.DEFAULT\CONTROL PANEL\COLORS and double-click the "Background" string.


In the "Edit String" dialog-box that opens up, change the values in the "Value data" field to the red, green and blue color values that you wrote down (e.g. 75 78 173).


The default value will be 0 78 152. Enter the values in the correct red-green-blue order, separated by a space. Close the registry editor and log off to see the changes.


Put Image in Log-On Screen Background
To put your favorite picture in the background of the log-on screen, click "Start", then "Run", and type in "regedit". In the registry editor, navigate to HKEY_USERS\.DEFAULT\CONTROL PANEL\DESKTOP and double-click the string "Wallpaper". In the "Edit String" dialog-box that opens up, enter the full path and filename of the image that you want to use as the background. The image must be in .bmp format. Click "OK" and close the registry editor. Log off to see the changes. hope this helps

Basic "background" colors are wrong:


Kathy...have you tried connecting another monitor to the same video card and computer? It could be...

1. Video card defective
2. VGA cable from computer to monitor defective...look for bent pins in plug.

The VGA cable from the computer video output carries three distinct colors...red, green and blue. Likewise one of these colors may not arrive at the monitor correctly or at all. The results being that all colors are incorrect.

Just reset your logon password. You can get a Password Reset disc download and burn to CD. Copy/paste the address below, into your address bar of your browser.
http://pogostick.net/~pnh/ntpasswd/cd080802.zip
Download this file and burn it to CD. Put into drive and turn on PC, and boot from the CD. Follow instructions, choose the correct USER. & BLANK the password. make sure you say OK to write the data, and reboot. The logon password will now be reset blank.
