SOURCE: LG monitor not working.

More likely to have failed capacitors in the power supply section, that will be the first place to check. Please see the pictures here so you know what to look for inside, post back what you find so we can guide you further and it will help other people also.

You should replace them in a set.

My LG FLATRON W1934S was working fine last night. went to turn it on this morning and nothing happened. no orange or blue lights and it wasnt left in sleep mode either. what could be wrong with it?
I would suspect a problem in the monitor power supply, either a fuse or possible bad filter caps especially if you had to turn it on several times to get it on just before it failed.

If you are able to open it here is what bad caps look like:

Screen flashed and stopped displaying widescreen
Usually this is because the display has been changed from 16:9 (widescreen) mode to 4:3 (standard) mode. On the front panel there's a button labelled "4:3 in Wide." Press this button to return to Widescreen mode. If it says "OSD Locked" then you need to hold the "Menu" key for several seconds to unlock the controls, before changing it to widescreen.

If that doesn't correct the problem then you need to adjust your computer's output resolution to a 16:9 ratio like 1920x1080 (1080p) or 1280x720 (720p.)

I have an LG-1934S. The screen won't turn on - power button continues to flash blue. Checked cords - unplugged plugged back in - blue light keeps flashing. Hit keys on keyboard and on mouse - nothing....
To find out where the problem is, you will have to try this monitor with another PC or try another monitor with this PC first to narrow down the problem.
Please post back after what you find out so we can help you further.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My LG flatiron W1943TB turns on, says analog power saving mode, goes black and then the power button flashes.. but the monitor is hooked up to my dell notebook bc my LCD died
Hi erin mckinle,
That is probably it's, uh, analog power saving mode. When the screen goes black and the power button flashes, make some mouse gestures or hit some keys that would not affect anything (try spacebar). That should bring up the screen. If you think it goes into power saving mode too fast, go to Control Panel --> Power Options, and change the values. Hope this helps.
