Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

Monitor STFC (Self Test Feature Check)
* Turn off the monitor
* Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation
* Unplug the monitor video cable from the back of the computer
* Turn on the monitor
* The floating dialog box should appear on screen against a black background. If the issue appears during the STFC, the monitor is defective. Get it replaced.

How to reset factory setting of monitor lg l1720B

Sounds to me like the button is stuck with pressure on the sensor. try moving button around a bit if it is a flat surface button then the surface is likely distorted and wont release it would have to be replaced at that point.
