If it's a CRT (cathode ray tube) then you're probably looking at a "throwback transformer" problem. It's a resistor on the main circuit board that helps to catch stray protons while the electron emitter on the back of the CRT is what generates the visible image. Sometimes this causes an actual short, when the resistor becomes overly charged. You can hear a loud, or repetitive clicking, just before and after the monitor shuts itself off. Try taking the outer casing off (MAKE SURE YOU UNPLUG AND LET IT SIT FOR AT LEAST TEN MINUTES, BEFOREHAND!!!) and either blowing out any dust or using a static-free vacuum to clean the unit out. If the problem persists, it may need repair/replacement. It's a nasty problem to fix.

Dual Monitors. #1 works fine. Plug inb #2 and #1 goes to sceeen saver and #2 stays blank.

Both monitors must be plugged in when the computer is started for the second monitor to be detected, and you must configure the second monitor once the computer has started
In windows XP: control panel -> display -> settings tab -> select second display -> check "extend my windows desktop onto this monitor" -> click apply
In windows vista/7: control panel -> adjust screen resolution -> select second display and then under "multiple displays" select "Extend desktop to this display"

Screen turns on 1 second then turns black

With a known working monitor try it on the computer. If the monitor stays on then you know the original monitor is bad. If the monitor goes off after 1 second again, then you know that the video card is bad.

If it worked on a computer at the IT person, it is most likely a faulty graphics card in your computer. You may want to get that checked out.

Monitor goes blank less than a second after turning on.

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
