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.

I purchased and LG Model# LP1010SNR on 8-3-10 at Home Depot. It was a floor model and did not come with an owners manual. It has a digital display screen. It is intended to run for several hours at a time as it is used for a greenhouse. When I went to check the AC unit. The display screen displayed (P2) and blinking. The AC unit will not come on. It has power but, will not come on. I turned to AC of and the reset button, etc., Again the unit comes on but will not operate. It beeps 5 times and stops thats it.


What happens on this unit is it will suddenly stop followed by a series of chimes. You can reset the unit, but it will end with the same set of chimes. My unit display had a P2 code. As mentioned above, I drained the water (small amount actually) in the shower. Note: There is a cap towards tha bottom of the unit that you will need to unscrew, then pull out the rubber plug. Fired up the unit after the water drain ... it worked fine. If they can make a GI Joe talk ... why can this unit simply say ... "Please Drain". P2 is so intuitive.
