Dell E172FPb monitor black screen green flashing power button

I have the EXACT same problem. Mfg: Dell, April, 2004, model #E172FPb. No warning of impending problem, just yesterday on power up suddenly I have a black screen and blinking green power button. When power button is repeatedly pressed the screen comes back bright as ever for a SPLIT second, then gone again. I attached monitor to another computer, and monitor does the same thing.

Your answer says that the switcher resisters are not working....but please tell me how to fix this?? THANKS!

You need to open it up and inspect the componente inside, look at the fuse and the transistors in the inverter circuits first, also look for sign of over heating on the board, see pictures here for the guide: http://s807.photobucket.com/home/budm/allalbums

Yep if you can you know how to desolder and solder...it is not hard although it is a technique that you can develop
you can swap out the boad too just have to find a parts source and and the machine needs to be taken apart. ccan you do this because if you have a service center do it it is not going to be cost affective . Knowing this you need to consider does she or dosen't she...only her tech knows for sure

My monitor went black, and the power switch just flashes.


is your CPU working properly? if that the case, your monitor is in need of a service.
reasons for why a monitor goes blank?
Reason 1: Wetness
The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.

Reason 2: Faulty Graphics Card
The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.

Reason 3: Faulty RAM
This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.

Reason 4: Loose Connections
Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.

Reason 5: A Short Circuit In The Motherboard
And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you.
try this.

have a nice day.

Dell E172FPb screen blinking


Hello,

If you've tested turning the monitor on without the VGA cable and it's still blinking I'd say there's a problem with one of the capacitors on the power supply card on your screen, when you're able to check it would you mind telling me the brand / reference of it ?
