Dell E175FP has dark screen. I tried to disconnect it from computer and leave AC cord only, the result is the same. While monitor plugged in to AC the power button flashing green, the screen is dark. I am saying it's dark but it's not complettely dead because there are very very low visible flashes also, they are hard to see. Seems like these flashes on screen and on power button going together at the same time.
I had the same problem. After buying another monitor and before throwing this one away I thought I would try plugging it in since it was sitting for a day. I still received the flashing light until I gave it a slight hit on the back side, it is now working fine.

Haa! This is hilarious. I've been scouring the Net for days trying to find a solution to the same problem. Most hits have lead to replacing bulging capacitors in the monitor. Then I saw this post, gave my monitor a whack and presto, display restored.
I'm sure there are still some electrical or mechanical issues and this is just a temporary fix. but I wasn't looking forward to opening this up and futzing around with circuit boards.
Thanx for the chuckle Gorgas!
There's something to be said about about this method...Just tap t in! Give it a little tap tap taparoo! It works
"I gave it a slight hit on the back side, it is now working fine." Worked!! Thanks Gorgas!

We had the same problem noted here. Dell PC & monitor about 5 years old (maybe more). A little "pat on the back" of the unit cleared things up and got the floating colored box. Reconnected to PC, and everything is good. Thanks for the tip Gorgas, that's not something I would normally have tried with expensive electrical equipment.

If you have the monitor on, but no video signal (for whatever reason) you should get a floating "Dell Self Test Feature Check" window with red, green and blue lines on it that shows the monitor is actually able to display a picture. Disconnecting the video cable is the easiest way to try to see this, and would show if the monitor can display anything. If you don't see that with the power on and video cable unplugged, then the monitor itself is most likely the problem (since you said the power light is on). If this is the case, you would need to contact Dell Technical Support to see about getting the monitor replaced, assuming it is still covered by its warranty. If you are not sure about the warranty, tech support will be able to check that as well. While it is bad news, hopefully it will help. Larry Dell Customer Advocate

Same problem. smacked the back of the monitor and voila. Thanks

Check the power supply (brick attached to the power cable). Does the light on it flash the same way the power button does? If so, you have a bad power supply. I could not find your model monitor on Dell's site, which means they don't carry it anymore. But, if you email Dell and tell them you need a new power supply for an E175FP, I'm sure they can sell you one. Or, you may be able to find it by putting your service tag in here: http://accessories.us.dell.com/sna/DellPartsFamily.aspx?c=us&l=en&RPU=1&s=gen

I just repaired two of these Dell monitors and they both had the exact same problem. Blown capacitors, it's about a 10 dollar fix and there are a dozen youtube videos that show you how. I almost guarantee any of you that is all that's wrong with your monitors. Apparently there was a flood of bad capacitors manufactured between 2000 and 2005.

I did figure out what wasn't wrong. We had another one that had a broken LCD, so I just swapped out the power supplies. That didn't fix it. Something on one of the controller boards went bad. Dell sent us a new one anyways.

I found out that it wasn't the power supply. After taking apart one with a cracked LCD I discovered the problem remained. The other had a good power supply so I just moved the LCD screen over to the busted one. Then dell sent us a replacement. so fixed one that had run out of coverage and had the other replaced.. that was nice of dell.

It's usually one or more capacitors heading south. Very common problem, unfortunately, if it is an older monitor it may not be cost effective to take it in for repair. Drop in to your local Thrift/Goodwill store. They usually have a half dozen older working monitors you can pick up for $20 - $30. A fraction of the repair cost.

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.
But can be a problem with inverters... control the transistors - MOSFET on the powerboard.
Good luck!

Amazing! Same problem. 2005 Dell monitor model E193FPc. Tried various combinations of pushing/holding buttons, unplugging power/computer.
Read on a Dell Community post from 2007 that it is likely a bad, "bulging" capacitor problem that can be fixed for $2-$4 and a soldering iron, with some carefully handling of the various capacitors, a multimeter - and take many pictures to get it back together correctly. I have don\'t have/never used a soldering iron, and didn\'t have any luck a few months ago when attempting a blow torch fix for a faulty \'08 Dell laptop video card, so wasn\'t interested in taking a chance with the soldering iron testing and repair. Resigned myself to needing a new monitor.
Searched one last time before shopping, found Gorgas solution above, slight slap on the back and "presto"! It came on. Amazing that the stereotypical, frustrated "hitting" of a technical machine actually fixed it. Hope it lasts.

My monitor does the same thing. I have a Dell Dimension 2400 that's about three years old. Lately, upon booting up, the monitor shows the welcome screen but then goes blank. The power light starts to flash quickly and a slight, ghostly flash plays on the screen. Nothing I try works to stop this, except tapping the plastic casing with my knuckles! After a few times, the screen starts to work normally. I'm getting fed up with this.
my E153FP dell monitor has the same problem. the power botton flashes green and the screen is dark with flashes.
I have a Dell 22 in. 2005FPW that is doing the same thing. It was working before lunch and when I returned the power button was flashing, and the screen was flashing on very briefly. I never did see any thing displayed on the screen though, it just flashes a black screen for less than a second and then repeats the cycle over and over. Anyone know what causes this, or better yet know a solution. I am willing to crack it open to try and fix it.
I am having the same problem on my dell 15" Monitor. But it only happens about half the time. The power button is flashing and that has a "Ghost Effect" on the monitor like others mentioned but nothing on the monitor shows. Then other times I will start my computer up and the monitor will work just fine. Not under warrenty anymore so I don't know what is best to do now.
