Question about LG Computers & Internet
If you are going to DIY and have proper tools and know safety precaution then please read on: Basic LCD monitor troubleshooting guide: Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
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 LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

plug in a different monitor temporarily, check your display settings (right click background, settings, advanced, monitor) and set refresh rate to 60hz. plug in this monitor again and see if that helps some monitors (lcd's especially) cannot handle beyond 60hz

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

I would say your monitor is bad if you have tried it on 2 different monitors and it does the same on both. Check your warranty expiration date, some monitors have 2 or 3 years warranty. If it's still under warranty, you may be able to have it replaced or repaired.

Hello sir, does your PC boots normally? The symptoms you describe also applies to a bad CPU. If you see the monitor brand or logo flash on screen, the monitor is good. check your CPU memory, try cleaning the memory modules, this requires you to remove the memory clean the terminals and replace it back again. If this does not work, I need more info. describe the behavior of your PC. beeps sounds lights, keyboard lights. etc.
