SOURCE: cable advice...

There's an adapter cable required to go from the Mac's external monitor connector to a standard VGA plug. You can see what it looks like here at the Apple Store site. Once you have the adapter you can use a plain old monitor cable with VGA plugs at both ends to connect your Flatron.

Lok for bad caps with domed tops as shown in my pictures here:
http://s807.photobucket.com/albums/yy352/budm/LG%201915S/

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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

HI I have used LG Flatron L1915S computer monitor. When I plug it into my laptop, it blinks showing the laptop desktop for less than a second then goes black. Other monitors works fine when I plug them...


There is often a function monitor key on the laptop, located near the F7 key area, the icon looks like a monitor on|off and is typically in blue. this key is to be used in combination with the Fn key to enable, disable the external monitor or enable both monitors or just the laptop. Press the key combination until your laptop panel lights up while the monitor is plugged in. Now check your extenal monitor refresh rate and resolution slider settings by right clicking on your desktop go to properties / video settings. (please note monitor settings are under advanced). You should see two monitors in there now. use "identify" button so you know which one to work with. on the external monitor settings, decrease (slide left the slider all the way). If you can set the monitor refresh to 60Htz. Lastly take a flashlight and check if you can see a shadow of your screen on the external monitor, if you can that means the backlight is not working and likely needs the inverter replaced. Hope that helps ! Cheers

I'm tring to restore original settings on my LG monitor and keep getting "osd lock" message. Half my monitor is very bright, the other half it 10-15 shades darker.


I held the "Menu" button down for 15 sec. and it unlocked. Then used the Auto Set feature. It didn't work immediately on the two-towned
screen, but corrected itself within 1/2 hr.

Thank you.

I turn on my FLATRON L.1730 SF but after a few seconds it says POWER SAVING MODE and the monitor remains black.


Try selecting a different input from the monitor's menu, perhaps it is set for digital input while you feed it analog VGA signal, or vice versa.

Based on your description, it appears that the monitor is faulty. Since it is only a week old, you should have no problem exchanging it.
