First, try it on another PC first.
Second, the video resolution of your PC should be set to 1280 x 1024 @60Hertz.
Unless it has problem inside, then you will need to open it up.
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 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.

My samsung LCD monitor display blank but blue light is blink.


Hi,

Check to ensure all connections are in good place and are properly connected, if they are and yet no display, the picture board on your monitor is faulty, since the power light is on, it means the picture board of your monitor has developed fault.
take the monitor to a local repairer within your vicinity to help with the replacement of the picture board.
