DELL 17' MONITOR STATUS LIGHT FLASHES, BUT WON'T COME ON
Hello, my dell monitor was working fine then one day, it tried to come
on but shut back off. then the status light just blinks about every
five seconds like its trying to kick back on. when you leave it
plugged in for a while it would finally "click over" and come on, i can
use it for about 2 days to a week, then it does it again. this time
however, the blinking eventually stops and the solid green power on
light comes on but has no picture. when you try to restart the
computer you get an image for about 2 seconds then the blinking starts
all over. i'm pretty good with electronics and i have a fluke
multimeter. i just have no idea on where to start with this problem.

The power light is flashing green can indicate start/restart of the power supply due to shorts circuits or failing power supply due to bad caps, look for bad caps with bulging top first, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Please disconnect the Monitor Data cable from Computer. If you see Dell Colored bars, it means, monitor is working fine, If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.
Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...
Blinking Green shows that computer is in sleep mode......
I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard
