Answers :

When you turn on most dell monitors they come on with a yellow light, then turn green when the monitor and video source synch. If your light is not turning from yellow to green, your monitor is either dead or not getting a signal from the video source it's plugged into. Verify in your BIOS settings that you have selected to output video through an installed card and not from the motherboard source. If the BIOS settings are correct, your monitor has died. If the light is turning green after you turn the computer on, press the menu button on the monitor and adjust the brightness/contrast until you have a picture. If you don't see anything when the menu button is pressed, then again your monitor is likely dead.
