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 LG and all other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Check the pins at both ends of the cable, also try it on another PC to make sure it is not the PC video card problem.

Firstly check the connecting cable from the screen to the computer at both ends. Ensure that the thumbscrews that keep the connector in place are tight. Has the PC been moved recently? Any chance the cable could have been put in the wrong place? You can get the installation manual on the following link to see where that cables should go: http://us.lge.com/filedown.do?filepath=1000000757&fileName=L1750B-BF.pdf Try resetting the monitor by pressing the "Auto/SET" button on the front panel for a few seconds with the PC on. If that fails you can do a full factory reset on the monitor by using the on screen menu and navigation to the "reset" function on the setings (gearwheel) page. This is described in the manual page A12. If all this fails then disconnect the cable to the monitor, the monitor should display "no input signal" if it does suspect the PC graphics card is faulty.

That happens when the monitor goes off but the inverter light failed to switch off. The triac on the inverter board is shorted and must be replaced. When the triac on the inverter board is shorted a continues voltage is supply to the inverter light (or cold cathode) making your monitor to look like a transparent white plastic.

THIS BIOS PROBLEM IN YOUR MONITOR.

If your backlight is broken, then your monitor is broken beyond economical repair. Unless your monitor is still under warranty, you should seek out a replacement monitor.

Press the OSD ("On Screen Display") button on the bottom-front of the monitor. Use the other nearby buttons to "navigate" through all the settings, to select "Brightness", and to move the level UP/DOWN.
Wait a few seconds, and the OSD will vanish, by itself.

Simple test: try to boot using another monitor; if it's the same then the booting process in your pc is seriously screwed-up - fix it; if not, your monitor is dying, try to fix it or replace it.
