Common problem: bad caps.
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). 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.

LG L1730S 17" LCD Monitor


Hi Anand,

You need to check your power options settings and modify it , so that your monitor does not turn off automatically.


If you are using windows xp , go in control panel and then there would be an icon for power options , double click the power options and then you would find settings which read turn off monitor , turn off hard disk etc... select the turn off monitor to never mode or as per your convenience and you would have your problem solved.

Hope this helps.

Hello there , i d like to express my problem here , with the hope to find a solution . I have an LG L1730s monitor for about four years . Recently i had a video card burn and i changed it with a new one ....


Hi
I've repaired a lot of these monitors and every one seemed to do something strange. In this case my first thought is that somehow he monitor firmware got zapped when the card was damaged. Although this could certainly fall into the category of an open ground in the cable. My suggestion at this point would be to take it to a reputable repair person and get their estimate or take a look at www.micromendllc.com.

My monitor lg flatron l1730s keeps going into powersave mode


check your powersaving options in windows>control panel>power options

there is a bunch of options in there that could make your monitor go into power saving mode.
also check your video card options and menu of the monitor itself all could possibly contain a sort of powersafe option.

most likely indicated with amount of minutes untill... either power off screen blank or screen saver.

Monitor flashes POWER SAVING MODE.. monitor dosnt turn on


A quick Google tells me this is a VGA analog interface monitor. Have you another monitor to test with, to see if the problem is the PC or the monitor. If another monitor works (esp. a CRT) your L1730s may still be fine. Set the refresh rate of the graphics adapter to 60HZ. then test your LCD again. Some monitors just blank the screen when they get a refresh rate they cannot handle. p.d.
