Question about Dell E173FP 17" LCD Monitor

1 Answer

Monitor dark but can see image in background

I have an E172FPb that initially would come on with a normal display for a few seconds and then go dark with no image in the background. I diagnosed two shorted transistors (Q759, 760 - 2SC5707). I ordered 4 of these from LCDRepair but replaced only the two bad ones (leaving two for backup). I also resoldered the 4 transformers near the four transistors. I can now see and image in the background that stays as long as the computer is on. Should I have replaced all four transistors even though the other two tested good? Could it now be that my backlight tubes are bad? Can the backlight leads be tested for voltage if they are disconnected from the lights? If so, what voltage should I get? Any help would be greatly appreciated. Dave

Screen keeps t going blank but still have power


It may be the internal backlight that is failing. When the display has failed but still has power, take a flashlight and hold it close to the screen, move the flashlight all around the screen and check if you can see anything. The display will be dark, but you should be able to make out the image that is there with the flashlight technique. If you can see an image on-screen, then your backlight has failed and you will need to replace the monitor. Weather or not you see an image is not a critical issue, but a tool to verify if the backlight is off or some other issue is causing the problem.
Note, it may be difficult to detect an image on the un-light display, for example if you have a dark image as your desktop background. So make sure to fully scan your display (top to bottom, and left to right covering the entire screen) with the flashlight technique in order to see any image on-screen.

Screen returned from supplier background bright pink, how do I change to white background.


To check if the video card or the Sharp LCD monitor is faulty, connect a different monitor to the computer. If this monitor displays a normal image then the video card is OK and the Sharp LCD monitor's back-light is faulty. Send it back to the supplier to have it fixed (they should not have reurned it to you in this condition).
If the other monitor also displays a bright pink background then the video card is faulty and needs to be replaced.

After a few seconds after boot up, the monitor turns black, images are visible in the background, but very dark. as if it is in a power saver mode.


Do you have brightness adjusting software. if so change the settings. if not there is something internally wrong with your back light.

Dimension of image change when displaying clear or dark image


Same problem Picked up this monitor about half a year ago, a Viewsonic A91f+, and have been having some issues for a while now concerning what appears to be shifting in the monitor image, but that is about the best I can describe it as. It is most noticable when a large dark area meets a light area, like text or window edges. This "shifting" only occurs on the right side of objects and seems to show most often after I switch resolutions more than a few times, usualy due to gaming. Ive also noticed it happening from running random programs that dont require resolution changing/flickers but this happens FAR less often. -photograph of the effect- As you can see, its pretty subtle on a darker background, but Ive had no luck carturing it on a light one. Anyone have any idea as to what is occuring on this monitor and how it could possibly be fixed? Possibly an issue with magnets? For a while, I did have a small headset hanging off the the monitor on the side that the images "shift" towards, but even taking those off and away havent fixed it. Currently the only fix I have found for this is to shut my monitor off for 5-30 minutes, depending on how bad the "shifting" is when I find a time break long enough to fix it.
