Your post regarding cap replacement

Hey there man, just wanted to say that I've browsed fixya here $ there, but rarely find any useful solutions; as most tend to go by the "make sure your PC is on" type. Just wanted to say that I really appreciated your post, and I'm jumping on those caps right now -
Sincerely,
Sean

Question regarding Dell 1707 FP 17" monitor: A few days ago, after two years of unsymptomatic use, the screen started to flicker and then go black after 15 minutes or so. Now the screen goes black...


Comon problem with these 1707 series (there are more than one version of this model) is due to bad caps or bad lamp assemblies as shown here:

http://s807.photobucket.com/albums/yy352/budm/DELL/Dell%201707FP%20Rev%20A01/

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I've read many posts regarding the Princeton Graphics VL1918 about bad capacitors, but I don't think that is my problem. I'm trying to find these stinkin drivers somewhere. I just got a new...


The driver is needed if the correct resolution for the monitor is not on the listed, it will not affect the sceen symptom that you are having. Color casting (Red, green, blue, pink, yellow, etc. color casting the whole screen) on the screen is usually caused by poor video cable connections or bent pins or bad PC's video card. I would check that first.

This monitor is known for bad caps for sure, and it can cause a lot of starnge problem.
We need to find out first if it is the monitor or the PC problem. You will not find win7 driver for this monitor since the company no longer support this old monitor.

When I turn On my monitor, it is displaying black screen after the message "No Signal - Analog" (normal/usual message). When I disconnect the VGA cable from the monitor, it shows the message and...


The VX series are cheaply made with cheap caps and they failed due to bad caps, see my pictures here: http://s807.photobucket.com/albums/yy352/budm/VIEWSONIC/Viewsonic%20VX2235W/
VX2235 came out years (2006) ago so I cannot see that it will be only 8 months old. I fixed many of these VX series.

Recommended resolution is 1920x1080 but my settings do not show that option. Was working ok, but now screen is somewhat unclear.


In case you can't show the 1920X1080 option (or higher resolutions) either the VGA controller can not handle these resolutions (so they are hidden) or the drivers for your VGA controller are missing. Clarify me your desktop brand/model to come back with more details.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

My Dell Flat Panel Monitor Model 1901FP goes black after it's on for 3 seconds. The green light stays on. I tried replacing cables. Any Solutions?


Inspect the power supply/inverter board for caps with domed tops first, if you do want to DIY repair down to component level, you can get a replacement board for $30.

Error message


I have issues with the f1703 monitor as wel - the OSD will not turn off - though the more common failure of this model is that the screen is black after a very short usage time period. Apparently, this model monitor was defective, and was recalled by HP. However, they failed to give notice, so I would recommend following up with them to attempt to get it replaced. Good luck! (Further, it could be that the defective monitor may be affecting Windows in some form or fashion, but I wanted to inform you regarding the monitor.)

If this information assists you in resolving the problem, please take a moment to rate the solution at a "FixYa" level. If you do not feel that you can rate at a "FixYa", please post back with more information regarding what has occurred subsequently and/or more details regarding the situation, and I will gladly help you until we have reached a definitive solution.
