The monitor is probably on protection.
To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.
If it is computer fault and no video signal , then test:
If it is monitor fault , then the monitor is on protection.
When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

I had a similar post about an LG 505G. Just bought a new LCD monitor and decided to open the monitor before putting it on permanent storage. I noticed a bloated capacitor in the control board just adjacent to the low voltage power supply. It was a 1,000 mFd 10V cap. So what the heck I desoldered it and replaced it with a spare 50V capacitor of the same rating I had lying around. I assembled the unit plugged it in and VOILA!!! the monitor was working again. Hope this helps.

check to see if any electrolytic capacitors on the power supply are bulged at the top, if they are replace them
