Activating the menu, volume and other games, a recurring problem with this model, changing the board is very expensive, so I used the following repower supply wsound tsound are front keys, I closed the jump between sk0 and sk1, you cancel the front and use it normally via the control and the LED stops blinking. | A jumper was made on the touch controls side plate, the LED stopped blinking and activating the functions, it is more viable than changing the main unit and using the cont. normally. | José delta line | |

This TV was constantly skipping channels, I saw tips on eeprom and even microprocessor | The cause was the 5v6 zener diode d004 which is on the side of the connector that goes to the micro switches | Replace the 5v6 zener d004 and run to the hug | <small> |

It turns on and off in a few seconds, the LED comes on again, and after several attempts it turns off in less time. | C 409 of 220uf /16v close to the bad oxidized video cable and open abl d501. | A lot of work but it turned out great. | George Pontes |

Does not turn on, LED is off, with power supply activation signal. | Found c2346 and c2347 of 47mf/160 volts dry (completely without capacitance), which, after being replaced and carrying out a general inspection of the other components, were found to be ok. | Put the TV on the network, it worked normally. | Luiz Cassiano |

Does not turn on, stand-by LED turns red, activating power turns green, but 12v voltage does not appear. | Optocoupler PC817 code board on NW950 and CI AZ431 code board on VW951 short | Replace the two components mentioned - be careful, only carry out maintenance if you are an electronics technician, ☠ risk of electric shock ☠ | Eletrônica Heinz - São José - SC |

Turns on, screen turns off, second goes into protection | High exhaust from the lamps with the housing. | Unplug the connector that goes from the inverter board to the light bulb board, measure possible leakage in relation to the housing with the light bulb board; if tsound is a leak in the connectors; dismantle the screen until you reach the board wsound the lamps are connected; underneath it, an insulator between the plate and the TV housing could have a possible spark point, just isolate it and go for the hug. | TV CENTER |

Doesn't start. When plugged in, the LED lights up and then goes out, accompanied by a rapid oscillating noise. | Diode d802 | I replaced it with a fr156, it worked again. Tsound's no point in putting just anyone, like the 4007. It has to be appropriate. | Romildo Behrend |

The TV turns on, it has a normal high, but tsound is no image, sometimes by increasing the screen a little the relay hits and the image appears then you adjust the screen back into place and when you turn it off and on again the relay hits but tsound is no image again. | Make a jumper on the l400 coil, if that doesn't help, do a general resoldering on the focus board, especially on the harness that comes from the main board. | TALL-TEC Eletrônica |
