Question about LG Flatron L1750S 17" LCD Monitor

1 Answer

I have a dual display at work. one of my two displays is the LG Flatron L1750S. When I go to lunch my LG seems to go into some kind of power saving mode and the screen turns off, but the green light at the bottom will blink. My other monitor has no problems coming back on, but no matter what I do, the LG wont turn back on. It acts like it is on in terms of I can pull screens between the two monitors, but the display wont come on. I cant even turn the power off using the button, it just keeps blinking. I have unplugged the monitor and plugged it back in, only to have the same result. Usually I can log off of my computer and log back on and it will start working again, but not today. Any ideas what would cause this and how to fix it? I dont want to have to completely power off my computer everytime I come back from lunch just to get my second monitor to work. HELP!

Monitor this gae will more likely to have bad DC filter caps: http://s807.photobucket.com/albums/yy352/budm/LG%20L1751S/

If you are going to DIY 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, 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/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 Flatron L1750S will not come out of "power saving mode" any ideas on how I can fix this problem?


Try it with another PC first, if still not working, then start looking at the power supply DC filter caps first.

LG Flatron L1750S LCD won't display anything...


Hi,

To your concern, a couple of suggestions:
  • if you could try again a reputable electronics service center/shop, pls mention for them to look at the CCF (cold cathode florescent) lamps, the inverter and/or the main board;
  • the blinking light is significant, it could indicate loss of video signal or internal protection kicking in;
  • possibly heat related, check for any of the capacitors bulging or leaking.
If they would reference a service manual or a schematic diagram, pls relay that it is chassis CL-82 for an LG L1750S. Foremost to check would be for the presence of both the 12 and 5 volts,.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Power saver


This problem is showing when the main PCB of the monitor failed. Mr. Ravis not to worry you have warranty, contact the LG service provider in your area. They will change the PCB. check this link to get the service center info

Screen shutting down


Well, Gestion Alim is French for "Power Management." It means that your computer is shutting off power to the video using the ACPI power settings, probably stand-by or hibernation. Bring up the Power Management settings in your operating system (in Windows, it's the Display icon in the Control Panel) and change them to something more reasonable. If you want to disable them completely in Windows, change to "Presentation" and make sure that hard disks and display are both set to "Never" shut-off.

LG Flatron LCD Power Saving Mode


Well thats seems tricky does it not come on at all when you boot the computer. If the screen is working then it should work to display the Start up screen. If it does then keep pressing Delete until the BIOS comes up- then search the pages for power saving and slect to OFF
