Re: Help needed!

It's probably a problem with the backlight or the backlight inverter... i had the same problem just a little while ago. If your electrical components savvy, you might be able to find the problem on the inverter (which is on the side of the monitor once you get inside). Otherwise look into replacing the bulbs (which are on the top and bottom)

I have a dell e198fp monitor con nected to a dell latitude d400. Got monitor from daughter who said monitor was working then went black and stayed same. I get a blinking green power button with a black...

I suspect you will find that there are bad capacitors on the power supply board. If you aren't handy with a soldering iron, however, I would not recommend this repair. It can be easy to permanently damage things. If you aren't afraid of that, however, give it a try.

There are two that I have found that typically fail (680 microfarad, 16 volt). They usually "bulge" on top after failing. I have found that the replacement value doesn't seem to be too critical. I wish I had written down the actual designators for these caps (maybe next time I repair one of these monitors).


Once you get the bezel apart and get down to the metal shielding, slide the shield on the right hand side to remove (arrows pointing to each other). There will be four connectors underneath this shield to power the backlight. Disconnect these four connectors, paying close attention to where they were connected.

Disconnect the small ribbon cable on the other side connecting to the front panel controls...There is a small black tab that will flip up to allow removal of the ribbon cable. CAUTION! THESE CABLES ARE DELICATE...DAMAGING THE CABLE OR THE CONNECTOR WILL DESTROY YOUR MONITOR.

There are four screws holding the power supply section to the LCD itself (two on each side). Once you remove these screws the rear shield (and power supply section) will start to separate from the LCD. There is another ribbon cable between the power supply section and the LCD panel...AGAIN...DO NOT DAMAGE THIS CABLE OR CONNECTOR! Squeeze the two black tabs on either side of this connector to remove.

You should now have the power supply board exposed. Remove the screws securing the power supply board to the shield. You will need to disconnect the connector attaching the AC power inlet to the board in order to access the top side...

The failed capacitors should be readily apparent. Replace them, re-assemble and test.

That's it

Dell E173FP 17 monitor went dark and not working. I restart the pc it shows for only few second and went out again. I plug in one other monitor in my pc and it work fairly well. So something not right with...


There are three possible cause why your monitor went black and start working..

1. If your monitor is dead set.. no reaction or lights turn on after power on.. then it needs to check if there is blown capacitor in its power supply section..

2. The high voltage ballast transformer of the backlight inverter is burned - it needs to be replaced so that it will not have a direct effect on the power supply section of the monitor.

3. The backlight inverters are all busted - the backlight was located at the upper and lower back edge of the monitor.. If these lights are busted then all that will be seen in your monitor is black screen.. It will need to be replaced so that image display will come out from your screen..

These 3 reason and its solutions can only be done by yourself if you have the knowledge, proper skills and the right tools to open the back cover of the monitor and replace the problem parts....

Otherwise, bring your monitor to a credible technician and if there is warranty,, avail of this...

Hope that answer your question..

Much appreciated if you rate this help..thanks..

I have been having trouble with the screen image moving to the right so that there is about a 2" bar of black in the left margin of the screen. I went to my control panel and adjusted the screen resolution...

you need to reboot into safe mode (hit F8 during boot up), then set the video to 640 x 480, then reboot into regular mode , then reset it again to the native resolution of this monitor, 1440 x 900 @60 Hz.
The monitor this old may also have capacitors problem,
Post post back so it may also other people also..

No DVi input, then computer goes to sleep

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:
  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.
