Does not turn on, nor does the LED light up | TV looked like this after lightning struck near the house, right away, tsound was a problem at the power supply | The 2 fuses and the 4 1n4007 diodes of the primary power supply were replaced, the varistor seemed to be in good condition so it was not replaced, the TV started working again after changing the components mentioned. | Lucas |

Turns off after some time. After the first shutdown, this repeats more quickly and then never stops turning on again. keeps turning on and off. | Zd503 diode (zener 15v) leaky/altered. only detectable at x10k scale. Measure to see if possible changes in the zd504 (15v zener, very close to the zd503) and ic 502 photo coupler. | Replace and you're done. | Eletrônica R-Tec |

This TV arrived at my store with a very clear image, you could barely see anything. water had fallen. | On the v-com board, I identified the problem location, cleaned it with isopropanol, and found four open resistors. rg7 (9k1), rg8 (33k), rg3 (4k7) and rg2 (30r). all close to ci(ic6) | I made the replace by removing the resistors from other boards and it was perfect. | <small> |

The image is drizzly and dark and only appears a little at the top. | R729.2r2 and capacitor c765 1k x2kv and I guided by the words of friends sound. | Replacing them. open resistor and cap. blown on the y plate. | @gepe (agripino sousa) Pá |

TV would hit the relay and go into protection. stand by access but did not accept the power on command. and none of the 5v voltages appeared on connector p813 | Transistors q801, 802 and the driver l6599d fuse f801. | Replacing them. | @gepe (agripino sousa) Pá |

It doesn't turn on only with stand by access when pressing the power key it just makes a hissing sound that starts to turn on but doesn't turn on | Ic301 shorted vertical output tda3653bkilling flyback oscillation | I put a new flyback with a new vertical outlet and it was good again | Lambuquenta eletrônica |

The TV kept cutting the sound due to the voltage of the q700 (mmbt3904) varying between 3.3 and 2v | What I did to solve the problem:. as I didn't find the transistor q700 (mmbt3904). I removed it from its place and left it without the transistor, the TV is working fine. | Obs. As I live in a small city it is a little difficult to buy, this was the solution I found but the ideal is to replace the component because the mute function stops working. | Reginaldo Alves |

When the automatic channel search starts, it just keeps tuning and doesn't stop, to finish the search you have to remove the cable from the network, and it doesn't save the channels, it gets lost in the automatic search | Electrolytic capacitor at the power supply with low capacitance c112 (4.7/100v), q100, q102 2sa1281, and can also be the tuning tuner | Check the capacitor c112 and the transistors q100, q102, in the latter case the tuner may be altered, as these components cause this type of defect, I have already had several with this defect | rubertan eletronica silva joao monlevade |
