I have a SyncMaster 931BF, which is a pretty nice 19 inch widescreen LCD. The problem is, when the power is first connected and the computer is on, the power LED on the monitor comes on, the backlight comes on as expected, the backlight stays for about a second and then goes off and stays off. The video is perfectly crisp and fine while the backlight is on, and Windows recognizes the monitor no problem. If I open a white window (read: notepad) and move it over onto that monitor, I can juuust see it, so I know the video is still working after the backlight is out. I had ideal lighting conditions one day, and strained my eyes to go through the LCD's menu, ensuring brightness (100) and contrast (70) weren't on 0. (I figured I might as well check, though I didn't think this would fix anything). I also reset all settings to factory defaults, with no change. What I later noticed is that if I turn the monitor off, (hit the power button after the backlight has gone out) I can't turn it back on again without unplugging it. This problem occurs using both DVI and RGB video inputs. Any and all input would be greatly appreciated!
