Most likely there are some parts that have become thermo sensitive with age. Many times electrolytic capacitors become thermo sensitive as they ware down.

The parts that are going out of spec are probably causing some kind of fault that the set's uPC sees as a fault and puts the set in to protection.

The service tech will use a heat gun and liquid air also known as "freeze spray" to cool and heat the suspect components to trigger the fault, and then reverse it. Once the parts are found, they can be changed.

TV won't turn on. flashes a series of 5 red lights instead of turning green


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.

Hi, i just purchased two LG LCD TV's the 26LD350 and the 32LD350 I'm worried that it does not have an off switch and only goes on to standby mode. you here alot about tv"s catching on fire because of this....


I have never heard of any LG TVs having a fire issue.
LG added this switch to help save electricity. "Going Green".
You see, this On/Off switch was added to kill the power to the TV when not in use. This switch stops the TV from consuming power by not giving it power to be in a “Stand-By” mode.
If your TV does not have this switch, you could simply unplug your TV to give you the added satisfaction it won’t catch fire.
I hope this information has helped.
Good Luck.

LG CT-29K30EX 29" TV plugged


LG CT-29K30EX 29" TV - We have the same symptoms as described. If you are a person who is not afraid of opening the back cover of your TV and replacing parts inside. this tip is for you. Contact a service person if your not 100% sure. Its actually easy, it involves replacing a small capacitor in the power supply section. You don't need to troubleshoot coz i've done that for you for free. Find this capacitor in the power supply. C801 with a value of 100uf / 35V. De solder and replaced it with the same value or a much higher Voltage rating e.g. 50V. Done! your T.V. is alive again. - Rey Tilles - New Zealand
