THE MONITER QUIT WORKING AND THE LIGHT IS BLINKING WITH A BLACK SCREEN

The problem is in the power supply board often caused by one or two capacitors that open, some will show a bulge at the top making it easy to spot.

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.

May be the problem with your Pc. If you can hear a beep sound when booting the Pc is Ok. Otherwise check memmory for loose connection.

The problem is not with your screen. Its the problem of Video Card of your system which is unable to send Video Signals to the Screen.

if monitor light is on, check the connecting data cable if it is ok then consult a technician.

first you need to isolate the problem to either the computer or the moniter. I would sugust that you hook a know good moniter to the compter and go from there. If the other moniter works then you have a moniter issue aif not chek the video card in the computer. good luck
