SOURCE: Screen goes black after 2 seconds

Simplest solution may be the screen resolution settings are set higher than the monitor's capabilities. Try lowering the screen resolution and refresh rate in the display properties or try booting to safe mode (press F8 when the Windows splash screen first appears) and see if the LCD will display the windows desktop. It that works, check your video drivers and the screen resolution and refresh rate settings.
If the monitor has the problem in safe mode and/or if lowering the screen resolution and refresh rate don't help then I suspect the a problem similar to one some Dell 17inch LCDs have. On the Dells It is usually caused by a defective voltage regulator transistor in the backlight inverter circuit. Troubleshooting that problem should only be attempted if you have experience at repairing electronic circuitry since it will involve testing individual components and soldering.

This could be one of two problems, the light in your monitor has a loose cable, or the light is dying. I have seen cold cathode lights that are about 10-15$ to buy and many instructions on putting them in yourself.

Solution 2, your cable is loose on the back of the monitor. Make sure you have the screws tightened on either side of the vga or dvi cable, both on the back of your monitor and on the back of your computer or laptop.

SOURCE: ViewSonic VA1930wm Screen stays on for

Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

Screen goes black but still sound


This is inverter or backlighting problem. Can you try switching it on and off quickly for a couple of times and tell me if these '2 seconds' get any longer'. If picture stays longer and longer before shutting down, one lamp needs replaced-if not, please replace inverter board
