Mostly the screen backlight circuit defected. If you can not DIY repair, send it to a repair store. You can do nothing outside of the monitor.
Hi and welcome to FixYa,

If the Samsung would not likewise work in DVI mode and the computer it is attached to is confirmed to be operational, then the described problem on a Samsung Syncmaster almost always could be:
  • inverter (most likely);
  • \012
  • power to the inverter or inverter / lamp controller (likely); and / or
  • \012
  • CCF lamp (cold cathode florescent) (least likely).
All of the above would indicate a backlighting problem and not setting or configuration. A way to verify a backlighting issue is to shine a flashlight at an angle to the screen with the LCD monitor  turned on and the computer it is attached to booted. A dark semblance of the desktop would be slightly visible. Options are:
  • consider a DIY (do-it-yourself) repair only if familiar with electronic components & circuitry, in the use of a DVM/VOM and a soldering iron. It would be an advantage access to a Service Manual or at the very least a schematic diagram;
  • \012
  • should you be uncomfortable with a DIY, seek the services of an authorized service center (specially if the unit is still under warranty) or a qualified professional.
It must be noted that there exists a possibility that it could simply be a heat related issue or a loose connection on any of related boards, a cold solder issue on the PCB (printed circuit board) or even a component failure (often capacitors) and therefore would not need a board replacement (if the attending tech is willing to do component level repair). Repair cost would then be dependent on the determined fault.

Good luck and thank you for asking FixYa.
