19LG30 won't turn on, the light flashes red and blue

Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

Hi rschutt01,

This kind of symptoms is an indication of out-of-regulation condition on the power supply board(this is where the power cord's directly connected). It is caused by leaky/dried electrolytic capacitor. It will dropped the normal working voltage of the power supply and disable the unit.






Leaky electrolytic capacitor has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. If your unit is not under warranty period, take off the rear cover and inspect the capacitors on the output of the power supply board. Once found replaced it with same capacitance and working voltage that is printed on its body itself. Upgrade to higher working voltage is another option. Watch the video below for more info regarding electrolytic capacitors.



Dried electrolytic capacitor has no physical indication of fault. You must have a capacitor checker to determine its condition and pinpoint the faulty one. If not available, you may replace all electrolytic capacitor on the output of the power supply, it will not cost you much because this is one of the cheapest part on this board. Another option is to replace the entire power supply board for your convenient, it will not required any soldering. Click this LINK for the replacement. I would advice you to double check the actual part no. of your board that is printed on the white sticker on the board itself to ensure you will get the right replacement upon purchasing.

Let me know if you need further assistance.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

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.
