Check for leaking/bulging caps in the power supply first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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.

Why did my computer monitor stop showing an image?


Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct.


OR

Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.
