Check the caps in the power supply first.
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.

The back light tubes are probably exhausted. They can be replaced, or you could try a CCFL to LED back light conversion. eBay.com has some kits for doing that.

Just monitor power on disply comes but after some seconds disply is gone


On Samsung 740 this is a very common problem with the high voltage impulse transformator in the invertor block. That needs to change.

Monitor is on but disply id black


Having a similar problem.  When I turn my monitor on, the picture tries to come on, but then goes black.  After several times, I may get lucky and the picture will hold.  Is my monitor about ready to give up the ghost?  Mine is a few years old as well.
