Ok, same issue here as well. Monitor would come on for 1/2 second and then the backlighting will go off. It's next to impossible to tell, but if you shine a bright flashlight at the screen, you can make out the video signal/desktop.
I have now replaced all the Capacitors except the very large one (didn't come with the kit that was available.) None of my caps looked bad (bulging) including the large one. Unfortunately, I still habe the same issue
So my question is....large capacitor replacement or something else?
take off the monitor data cable from pc and try to turn monitor on if appears a smal square on the screen that mean your monitor is ok , and the black screen reason maybe data cable or vga card.
note : your monitor resolution is 1680x1050 some times wrong resolution cause like this problems

I had the same problem with this monitor (Samsung 943nw) When turned on it would only stay on for less then a full second. When shining a light on the screen I could see what was on it, so it was just the backlight that was shutting down.
After I turned down the brightness of the monitor, the next time I powered on the screen the backlight stayed lit and it was back to normal.
Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...
it sounds like the inverter was defective, the monitor will be fine for few seconds then go off but power light still stay on with Green. You can contact with manufacturer for repair service if it still under warranty.
The problem can be caused by bad caps in the power supply, bad inverter backlights circuits, bad lamps. Look for bad caps first, then post back what you find so we can guide you further, see example of failed monitors due to bad caps here: http://s807.photobucket.com/home/budm/allalbums
The power can be bad caps in the power supply or bad inverter circuits, start taking the back off first and look inside for bad caps first and report back, see example of failed monitors here: http://s807.photobucket.com/home/budm/allalbums
maryfoldesi1, Your monitor power supply is going into shutdown mode becauce it has detected a fault within the unit. A technician will need to evaluate it. Before doing anything visit YOUTUBE to view vid clips of "LCD monitor disassembly" and "LCD monitor repair" Also read more of my responses to other owners that have BLACK SCREEN problems and find out all your options you have open to you. You did not tell us if you can still see the Win-desktop AFTER it goes BLACK. Is it also BLANK or can you still see a faint image on lcd panel if holding a bright flashlight 1 inch from screen? lmistyrel on aim.com 12fixlouie on fixya
