I have a Dell flat screen monitor which starts up then goes directly to a black screen. Once I hit the power button, it flashes the image then goes black any suggestion?
Commonly, when I see that problem (especially Dells) it is the backlight that is failing. You see an image for an instant then the screen is black and the LCD power indicator is still green (ON). You can try to get the backlight replaced, but it may be cheaper to purchase a new monitor.
A test to verify if it's the monitor or something else would be to try a known working monitor on your computer to see what happens. If new monitor works, then your old monitor is bad. If new monitor does same thing as your old one, then you may have a system issue (motherboard, video card, software, hardware config).
Best of luck.
