If you have a problem getting into safe mode using windows Vista or 7, boot up your computer. As soon as it tries to start windows turn off the power. When you try to start it again it should come up with a menu asking if you want to use safe mode or boot normally. Select safe mode.
simcraft's link was great ! It has pictures showing the dismantling procedure, but the document is in Chinese and so is the web site where it is located. Please remember that some internal components can retain a dangerous charge of electricity for a few minutes after disconnection from the ac outlet. Wait at least 5 minutes before attempting the disassembly. Try to find the service manual for any other LG LCD in your language and read the safety procedures - they are pretty much the same for all models.
it would be helpful to know which monitor you have - each one is a little different...
basically, you need to press the "menu" button on your monitor, use the arrow buttons (on monitor, not keyboard) to get to the brightness adjustment screen, hit set, then adjust with arrow buttons, and hit set again, then menu to exit.
When an LCD Monitor starts to respond like this it is due to one of three reasons a power supply is not generating enough power to properly power the LCD or the LCD's backlight is beginning to burnout, and last the inverter is bad. These things all can be replaced, but it is not worth the cost! Easier and cheaper to buy a new one!
