Try it with another PC first and also check the cable since it acts like it is not getting the video signal from the PC. If it still does not work then you will have to open it up and troubleshoot it.
It may have dying power supply due to bad caps.
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 (they should be replaced in a set), 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 SAMSUNG 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.

Hi there,

Yes i do agree with you there is no problem with a graphic card,and i suspected it to be a problem with the cable which is used for connecting but it was fine when you swapped the monitors however i would still suspect on the slot where the cable is connected,may be you should try samsung service center before you decide.

Post back for more solutions we will be happy to help you.
Hope this helps.
Cheers!!!!

This is a problem with the power supply unit inside the monitor, there is no easy way out here. If you keep on using your monitor like this eventually it won't switch on no matter how long you wait. Keep on using it like this for the time being without switching off anything but ultimately you will have to take it in for repairs or otherwise purchase a new screen..
