Power supply stopped, without 5 volts | Look at the 3 1m5 resistors r9317, r9318, r9319, most likely one of them is open, just change and celebrate another case solved without the need to buy another power supply. | Alberi F S | |

Burning led. | High voltage/current. | Replace the LED bars and replace the value of the smd resistors r740 and r748 from 4r7 to 6r8 | evando viana |

Scrambled display | The voltage at q351 was wrong, it should be -30v at the emitter and it was 1.7v, I replaced it and it resolved it! | Robsonbis | |

TV flashed, power led, smart soon appeared and turned off, kept repeating | Auxiliary supply feedback pin 2 of ics801cs | Replace without measuring ds804 | edmilsompimentel |

Changing channels and turning it off by itself | Problems with touch panel. a lot of oxidation even after cleaning the defect remained. | It was necessary to remove the keyboard control integrated, maintaining only operation via cr. | Jefferson |

Sometimes when it turns on it comes with an image. hour without image. normal sound! and voltage that powers the tcom board varies downwards, remaining between 6.5 and 10 volts when normal is 12 volts | Precision resistor. r209, from 9k1 | Nunes | |

The green standby turns on several times, but it turns back to red several times, and it only takes a lot of trying to turn it on. | Power supply board defect | Exhausted capacitors on the power supply board, c310 and 311 of 1000 by 25 volts | Galileu Rocha |

Sound only goes up to 12 menu does not select function boxes | Enter service mode press the control sound once, release and press again and hold the two TV volume buttons together and hold for 5 seconds, | Save the service mode press s on the control once and release press the second time and hold and press the channel key going up and hold for 5 seconds the TV will turn off and restart and ready it is saved and configured. | |

Won't turn on without 5v | On the power board (small board in the middle of the TV) 12v comes from the power supply board, 5v is generated on this board and goes to the main board, on the 5v line tsound is an inductor coil, this coil was soldered cold | Resolder inductor coil power board, L824 coil, resolder power supply board as well | Claudio Eckert |

The logo appears and the LEDs turn off, but the sound remains. | Defective LED bars, burned out or shorted LED. | Removing the 2r2 smd resistors (rb13, rb14) to lower the voltage on the leds to 29.2v the television will work normally. In my case, I only removed 1 rb13 resistor and it solved the problem. | JKSTek |

Turns on the logo appears and turns off | Removing the 2r2 smd resistors (rb13, rb14) good luck | Removing the 2r2 smd resistors (rb13, rb14) good luck | JeanJKSTek |

Turns on, everything is normal, after a few seconds it turns off and restarts. turns on, Philips, turns off and stays like that the whole time. | Monitor the voltage on the 3.3v regulator u701. It has to be 3.3 volts. in my case tsound was 3.9v. | Replace u701, 3.3v regulator. | arock |
