Turning off, blinks 6 times LED symptom | The LED kit was changed and it continues to turn off and the same LED symptom, normal LED supply voltages. | Aluminum on one or both sides of the LED strip grounding on the TV housing, both have to be isolated from the housing, just isolate them with Kapton tape or whatever you prefer and run for the hug, I hope it helps. | Assistec LG |

Vled voltage (35v) varying between 24v and 42v and causing the activation of error 6 protection (backlight-error), but it was not caused by any backlight leds. generated a high frequency noise in the inverter coils. | RT resistor (150k) on pin 34 of IC 9500 altered by air humidity. | Substituir o resistor rt (150k ) do pino 34 do ic9500 | leitemarcellus |

Does not turn on, standby flashes 3 times and repeats the cycle | Defect in the hdmi ci, tsound is a short in several capacitors and in different sectors of the pci, after removing the short hdmi ci disappears. | Replace the ci with another and celebrate, correction from the previous post | Luiz Sena Eletrônica HYK |

Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis | Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis | Tsound's even a soldering point, it's the smallest point: Rodrigo Cofferi | Rodrigo cofferi |

Flashes 6x LED stby protection | Remove the cable located at pin 3 of the cn6401 "power supply connector" from the connector, bl_error, ground the cable on the side that goes to the main PCI. If the atv turns on, tsound is an open LED on the panel that activates the overcurrent protection. | RUBENS S.OLIVEIRA | |

Right after switching on, the LEDs turn on, protection is already activated and error 6 keeps flashing | LED drive circuit, after the help of another board I was able to remove the LED drive c.i. and place it in the place of my board. this c.i is the one with several smd terminals on the right side of the board, ok...I forgot to check the position and now that I'm posting the tip I remembered | Replace c. i drive the LEDs, be careful with the soldering station, components fly out if the air is too strong. | MIGUELTV |

The 4.7v voltage of the detect is missing | D21 getting very hot | Just replace the c56 (smd capacitor) of 500nf | Deo Eletrônica 8198904-0186 |
| SONY |
ADP-200ER AA
|
No voltage at the stand-by connector | 1v voltage missing on pin 1 of ic31 | Zd39, zd202, d37 and c46 all leak | Deo Eletrônica 8198904-0186 |
| SONY |
KDL-40NX700

Turns on, lights up green, gives a quick flash of LEDs and the LED stays red with an error of 6 blinks. | In my case I had a LED kit with cable and everything and I tested it, I was able to confirm that it wasn't LEDs, I also had a 40w655 main board and I tested it instead and it worked perfectly, even the power supply to the LEDs crashed, I thought it was strange, but the pwm must correct it as it "sees" the consumption of the LED kit and corrects it. | Changing the main board, I'm not trying to find out what it was...that's for another opportunity. | MIGUELTV |

TV restarts 3 times and turns off with the LED flashing 6 times. | The bd9397efv c.i was arming the protection...I changed the leds and nothing, I cleaned the leds and nothing, I changed the c.i itself and nothing, I changed the 39x50 capacitor and nothing too...so what I did was the following... pin 31 of the ic 9001 is the timer protection, and on this pin tsound is a capacitor, I removed it and put a 10k resistor to disable its protection... and the TV worked without turning it off again, I left the TV in test for 15 and without presenting the defect. | Put a 10k resistor on pin 31 of the ic9001 and remove the capacitor on this pin 31...tv ok | eletronica cachoeira |
