Question about Samsung SyncMaster 940N 19 inch LCD Monitor
Look for bad caps first on the boards per Louie suggestion.
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, 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/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.

Jgddy09, If you find out how to "part" the front "bezel" from the "rear cover" by watching some video clips at YOUTUBE, then you may want to visually inspect the "switch-mode-power-supply/ccf-lamp inverter board for BAD (failed) dc electrolytic filter capacitors that may or may not have the brand name of "CapXon" printed on them. Plenty of pictures on the web of this BIG PROBLEM!!! Let me lmistyrel over on aim. com or 12fixlouie on fixya know what you see on the printed circuit board. Also do some reading in my and "budmrtn" and "buddymc" fixya profiles. All that you need do is type nickname in the "search for sol.... "bar on the fixya screen and click "search. Then you can read to your heart's content to discover solutions to the BLACK screen of Death and then decide the fate of your monitor. Have you done the Flashlight-test?? I always look at the power supply(SMPS) board first!! Tell us what you find inside. good luck. 12fixlouie
