Question about Samsung SyncMaster 940N Flat panel Monitor
Hi, my screen has a problem, it stays on for 2 seconds (after i switch it on) and after it goes completely black.
in those 2 secs the image is perfect, no problems.
but it works only for two seconds.
the blue light of the on/off switch remains lighted like when the screen is on.
the only way to exit the blackness is to press the on/off switch twice (one for shut it down and one to turn it on) but it has the problem of the two seconds up and nothing more..
Simplest solution may be the screen resolution settings are set higher than the monitor's capabilities. Try lowering the screen resolution and refresh rate in the display properties or try booting to safe mode (press F8 when the Windows splash screen first appears) and see if the LCD will display the windows desktop. It that works, check your video drivers and the screen resolution and refresh rate settings.
If the monitor has the problem in safe mode and/or if lowering the screen resolution and refresh rate don't help then I suspect the a problem similar to one some Dell 17inch LCDs have. On the Dells It is usually caused by a defective voltage regulator transistor in the backlight inverter circuit. Troubleshooting that problem should only be attempted if you have experience at repairing electronic circuitry since it will involve testing individual components and soldering.

I gave it back in customer support, it was broken.
they gave me a screen that works (obviously 940n) i dunno if it's another one or the same repaired.
