Those lights are a code. I don't know which TV you have, exactly. But the manual will tell you what the light code indicates and what to do about it.
SOURCE: LG Flatron L1550S power light blinks green.
shorted components on the circuit. send it to a repair shop if you don't have experience on electronic troubleshooting!!!

there is ovbiously a fault with the monitor and w ould be best if you bought a new up to date monitor then if any faults consist with that one you could just take it back

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 statebecause 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.

t certainly seems like the monitor is not getting a signal. Did this
happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,
