My dell e173fp monitor has quit working. The

Is the power blinking amber? This is a DPMS power-save mode. With the computer disconnected and the monitor on, do you see the colored self-test block floating around? With the monitor on, computer connected, and you still have no image displayed, take a bright flashlight and examine the screen closely. If you can see a very dim display in the screen, the fluorescent tubes which light up the *background* and provide the vivid picture(sort of like a how an x-ray picture viewer works) are defective. The power light blinking may be the power supply sensing the non-functioning tubes or it could just be bad. If your display is under warranty, replace it. If not, trying to have the monitor repaired for this type of problem is almost as costly as a new one--and there won't be an active warranty on anything else that might fail. Hope I helped you.---Rick
