Question about Samsung SyncMaster 940N Flat panel Monitor
I have a Samsung Syncmaster 940n for less than a year, all of a sudden the monitor just went blank (white) - thought shutting it down may help but next morning same thing as soon as booted up white no imgae what so ever, could this be a driver problem?
This is a known symptom of a failed power supply board. Here is a repair guide for this unit that shows how to dis-assemble the unit and then what to look for and replace to rebuilt the power supply board and bring the monitor back to life.
And here is a picture of the power supply board.
I hope this helps you, if so please rate my solution.

I don't think the driver is a problem. This is the way how to examine
what's wrong with your LCD monitors. After you turned it on and the screen
went black, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know.

I have the same problem with my SM 931C. The display remains white even when i disconnect all DVI and Analog inputs - just filicker to black. It flickers to black 1-2 times also when i change Sourse modes (Digital/Analog) from the screen buttons but the display returns white. The message windows (Digital Source / Analog Source) and screen menu don't appear at all. I can only change its state to full black by disconnecting the power cable :)) but when I reconnect it goes white again.
