This worked for me before, but now the problem came back after being fixed for months! unplug the two connectors at the back of the tv, the ones that look like computer monitor cables. then go to top of tv and use manual controls, turn off main power, then turn on while holding input and vol down button, a small service menu will come up, use the channel up down button to go to test, then push input button, there should be a box with reset and some number in red. use the vol buttons to reset to 0, then power off.... reconnect the cables and then turn on the tv.

Usually Sony and LG Blinking Codes are the same. Here is what I have.
Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
One blink - not used for the self-diagnosis
Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.
Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).
Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
May i know, what's your lcd tv brand and model? When the light change to red color, is it a steady light or blinking light? Or you need more info on repair lcd tv, please visit this site http://lcd-television-repair.com .It may be can help you solve the tv problem.
if you are not technical i sugest you have this checked out by a professional most probably a fuse has gone from iside or your driver board has gone down.
The blinking should be normal after you have turneds it off because some capacitors will be discharging.
