HI Jamil , I'm french technician and I solve this problem yesterday .
For your problem yo cans change capacitor C6 , C26 220uF 25V 105°(105° is important for longer life of you'r screen).see this vue
Yea I get the same problem. PLEASE HELP!
The unit will probably require electronic troubleshooting in the power supply / inverter section internally.
SOURCE: I have a Dell E173FP
Look for bad caps, shorted transistors, fuse, cold solder joints.
If you are going to DIY 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 DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

i have the exact same problem you could write a more detailed solution please
My monitor will display for about 1 sec then blank out - I have to keep switching on & off to see anything.
I have had the same problem. I appreciate if anybody knows how to solve this problem. Thank you.
SAME PROBLEM. AFTER A FEW SECONDS, GOES BLACK AND HAVE TO TURN OFF AND THEN ON TO SEE SCREEN. THEN BLACKS OUT AGAIN....
I have a dell E228WFP flat panel monitor that is just under a year old. In the past 4 days or so when I sign in, the monitor screen goes blank. Time intervals vary between 10 min to 2 sec before monitor goes blank. I did monitor diagnostic check disconnecting white cable..self test dialog box appeared for a few minutes..then that went blank too. One interesting note though...if you place a flashlight angled against the monitor screen, you can see a "faint display" of the current web page. Upon further researching, I came across a similar complaint with this response...."If monitor is LCD, place flashlight against screen and if you see a faint display,backlight or power module is kaput". Upon writing this, I did happen to swap out with a smaller/cheaper monitor that I had as a spare, and for about 1 hour now....problem seems to have disappeared...at least for now. Hopefully my new monitor is still under warrenty. Can anyone offer help or comments??
Can someone show how to open the back of the LCD E172FPb.
