Question about Dell E173FP 17" LCD Monitor
Help. My Dell monitor repeatedly pulses - briefly flickers - but not long enough to see an image on the screen, while the power button just blinks green. The pulsing is constant, maybe once per second, over and over. The monitor behaves like this even when disconnected from the computer. The computer is fine and works with other monitors. In the past, I've heard a random "pop" from the monitor every so often, but never had any problems. Any advice would be greatly appreciated. Thanks
Check inverter board for bad 2sc5707 drivers...could be shorted.
Also check driver transformers for over heating symptoms...they could also be shorted.

I had this problem as well. To temporarily solve it, I would just unplug the power cable from the back of the monitor for about 10 seconds. When I plug it back in it would work normal, until the next startup...

This is the way how to examine where the problem is. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. It can be easily replaced. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
