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.

When i turn on my lcd samsung syncmaster 540n it displayed a lot of colored vertical and horizontal lines.no video when i attached my cpu but it turns on when i powered my cpu


boot up in safe mode (press f8 while booting) If your monitor works now, you need to go the the samsung site and download the driver for you monitor. I assume windows 7, since that is where most of the monitor problem occur.
