Dell E173FP Monitor Problem

After starting computer the monitor's screen will come on only momentarily then shut off.  The computer continues to run but no monitor activity.

When I try turning the monitor off then on again, it will go through this identical cycle of coming on for just a few seconds then shutting off.

    I have Identical problem - can get monitor to stay on by slamming against desk and then never turning off computer.

    Also try resetting monitor to all factory settings.

    Monitor turns on for 1-2 seconds and then goes off at start up. If I turn the monitor off and back on it repeats the same issue.

    Monitor stats up for a moment then blackout while still on. Have to keep turning on and off to warm it up then it stays on eventually.

    Same problem here, with the 19" model. green light on the LCD power button, goes on for only a second or two then just blacks out. Power button stays green, PC is still running. When I put it off and power it on again, displays an image but blacks out again after 1 second. Tried another monitor (CRT), everything is OK. Tried the LCD monitor on another PC, same problem.

    Monitor went blank (black) while using it. Will not run Self Test (disconnected from PC per Dell Instructions) and Power Switch Blinks Green On and OFF all the time (it will no longer switch the monitor off). Unit as manufactured in Nov 2004.

    Yep, same monitor, same exact problem.

  • pickledx3 Sep 16, 2008

    Monitor goes dark then turns back on. Repeats about every 20 seconds.

  • jimmyboxall Jan 03, 2009

    Exactly the same problem. Turn the monitor off then on it comes on for 2 seconds then turns off.

  • Arley46 Feb 26, 2009

    Same thing: During power up the screen will light up for a second then go dark. I've replaced my 17" Dell with a 19" HP and everything is working fine. I'd like to repair the Dell for my other system.

My Dell E173FPc exhibited this same problem as described by many people on this site. Having looked through the solutions I decided to investigate further.

Posted solutions point to a faulty 12V smoothing capacitor, dry joints on the inverter transformer or faulty driver transistors. All these were Ok in my case, but on closer inspection a dry joint was found on L202 – see picture.

Cleaning off the old solder and re-soldering fixed the problem.
So if your monitor exhibits the same symptoms carefully inspect all the solder joints of large components around the inverter.

I think it is the inverter board on your monitor. If you can dimly see the display wheh holding a flashlight to it, then that is
your problem. The invertor is not back lighting the screen and that is why you cannot see the image.

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.

    Did you try your monitor with another computer? If not, you should test your monitor with different computer and see how it performs.

I replaced the 1000uf 16v cap on my 15 inch (the original was swollen) and it seems to work fine now. I must sonfess though that I didn't use a proper replacement, I just gutted a 2200uf 16v cap from a burnt power supply.

Dell E196FP TCo99 Monitor screen problems

The screen colour changing is apparently an auto test procedure on the monitor and was prompted by a fault with the monitor not automatically shutting down when the computer is shut down. The settings on the monitor have been adjusted to rectify this and the problem is now gone.

Dell E173FP - After sometime the screen switches off

Sorry not a solution - but I have started experiencing the exact same problem over the last month although sometimes, on switching on again, it will run for 10-15 minutes before the problem re-emerges. Initially I put it down to the v. hot weather in July but it still continues. So I would also appreciate any solutions!
