My moniter turned on and off when i power on. after turning the power on and off few times, the moniter comes on. However after about a month of that my monitor won't even turn on Thanks

You should check the "Power Options" when the computer "Sleeps" & "Hibernates". Go to the "Control Panel" if you Win 7 or below, if you have Win 10 just type "Power" on the "Search Box" on the bottom left of the screen and then click "Edit a Power Plan" and set when the Computer "Sleeps" and when it "Hibernates". Basically when you move your mouse you are waking up the Computer from "Sleeping" or "Hibernating". Goodluck.

that will be capacitors problem in power board in the moniter

I suspect your computers power setting are turning off the monitor and not reactivating it (waking up) I would suggest attempting to change your power setting to never turn off monitor and see if that fixes the problem.

Please let me know if that works if not I can go over a few trouble shooting steps with you.

Thanks

I have lg flatron l1730s lcd black color monitor. I have problem with this. Power not come. some time when i connect it power LED blinking once then no display.

Unplug power. Unplug VGA cable. Remove back of monitor. (four small Philips headed screws along the bottom rear. Remove screws attaching Monitor to it's base. Carefully, lean the screen away from back of case. Gently unplug 25 pin cable from the screen.
Connect AC power.
Screen should power on Gray to White. Ble light comes on Blue.Flickers then changes to Amber.
Reconnect VGA cable. Monitor should work.
Close up the monitor in reverse order to opening it.
If these steps don't solve your monitor, consider replacing as cost of repairs may shock you.

Did you try turning it on that day?? wet??<--not good

If not it should be dried.

Open the back and look to see if its wet to be sure but it should be good to try after a month of drying

go to properties in desktop n look for screensaver then power then look for monitor off time

take the moniter to a known good pc and see if it work if moniter works correctly it is your video card if not you need a new moniter

I WOULD REMOVE REAR PANEL AND LOOK FOR A MASTER RESET BUTTON OR A BLOWN FUSE ALSO CHCEK
YOU AC ADAPTOR TO SEE IF IT IS WORKING FIRST.
