Could be a few things, firstly check that all the cables areinserted correctly into the back of the monitor, if the VGA cable is notconnected/lose it will cut out to power saving mode. This includes making sure it's in the PCcorrectly, try tightening and screws or clips that are on the cable.
The VGA cable is the one that runs from the back of your PCinto the monitor.
Then check the powercable, the one running from the plug into the monitor, is inserted correctly.

Look for bad caps with domed tops in the power supply/inverter board first.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: 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).

Plug a spare monitor in the computer to see if works, if it does! the LG monitor has issues and not cost effective to have it repaired. A final thought! make sure the power and video cord are snug tight on both ends of the LG monitor. If the same problem persists in both monitors, the computer has a Video Graphics Card issue.

Paul you might want to take a look at this fix and see if it helps.

It does the same with another PC? Video cable is good?
If it is the monitor, then look for bad caps as hown here first:

Hello Lawrie,

You don't actually adjust fonts or resolution on the monitor, you do adjust them in the control panel of the computer. To do this, open your start menu, select Control panel. When the control panel is open check the top left corner to see if it is in Classic or Category view, if it says Category, click the switch to classic mode link. If you don't see this in the top left look at the top right and look for Category or Large Icon View, if Category is selected select Large Icon by clicking on Category and then clicking Large Icon View in the list that appears.

Once in the proper view, click on Display and depending which version of windows you have select Settings on the top of the properties window(XP or older) or adjust resolution from the left column(Vista/7), now find the slider bar for resolution and slide it higher if you want the font smaller or lower if you want the fonts larger. This will set the number of pixels on the screen.

The default and best resolution for this monitor is 1280x1024, if that makes the fonts too small try 1024x768 next and 800x600 last. If the resolution is set too low to see the Ok and Apply button simply set the slider bar then press the enter button the first time, then you will be able to see the Ok and Apply if you need to continue adjusting.

Hope this helps Fixya,

Chris

Reply back with your version of windows if you require more specific instructions or pictures of any of the steps.

It may have dying power supply due to bad DC filer caps in the power supply, that will be the first place to look.

You will need to turn off power saving mode. After you turn that off the screen will stay lit. If power save mode is disabled and you are still having this problem then you will need to dismantle it and refit the multi pin plug tightly and re secure it using black electrical tape. The small yellow tape the manufacture has used (Phillips) was not sticky enough to hold it together.

Check the fuse and caps in the power supply first.

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

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.
