dell external monitor connected to desktop - used to extend desktop screen. however, the screen goes black after about three seconds. i'll press the power button (the green-backlit power button turns from green to orange) and turn it on again, and the screen comes on for a couple seconds and goes black again.

i am not able to tear the thing apart and look at lamps and transistors or anything like that. any ideas as to what is going on?
 
Solution
Likely something has gone bad on the inside of this system. This solution may sound stupid and you might have already tried it- but ensure that the video cable is plugged in properly and make sure that Windows dual display is set up correctly. If it still doesn't work after that, I would say that your monitor is dead.
