TV doesn't turn on with red LED. | Shorted capacitor c 820, at the input of regulator n803, which produces a voltage of 1.5v. | MARCOS | |

TV had normal stand-by, when giving the command on the button to turn on it turned on with the vertical closed and it was noticed that the semp logo appeared and then it turned off | "d301" this diode is naughty, don't trust the multimeter reading when it comes to it... | Replace d301 without measuring. | Edfesom |

No image. the logo appeared and erased in 2 seconds. just keeping the audio. | To avoid return, I changed the current of the LED bars. I placed another resistor in series with the r765 (2r2 + 5r6) smd. the 91.2v voltage dropped to 86.2v, and the 271ma bar current dropped to 174ma. | Eletrônica R-Tec | |

|
Does not turn on, nor does the stand by LED | Measure n805 middle pin with the negative housing, if it is shorted it was already a processor. If it's not shorted, tsound's a solution! | Replace nw910 and nw955 both are shorted primary and secondary power supply sector. I hope I helped!! | Maike Sorriso-MT |

Turn on the logo and turn off the backlight, sound is normal. | Tsound is a way to disable the protection of the ssl100sn ci, to do so, place a resistor (1k) from pin 2 to ground, if that doesn't help, also place a resistor (1k) from pin 8 to ground. | EC | |

TV without image, but had backlight | Defect in the v-com, shorted capacitor was killing the 15v of the avdd, | Replace capacitor c25 with another of the same size | Tec. Daniel Schmidt |

Does not turn on; When connected to the network, the green LED lights up and goes out | Corrupted flash memory | Re-record the flash | Julian C Braga (Hitech) |
| SEMP TOSHIBA |
LC4241W
|
Does not turn on, without voltage of 5v and so on, does not hit the relay | Capacitors c866, c842, c843 all 22uf/50v open | Touch the same | Julian C Braga (Hitech) |
| SEMP TOSHIBA |
LC3246WDA
|
Does not turn on, LED changes from red to green, but no image | Power supply without 12v and 24v | Check resistors around the IC of the NCP1653A PFC, to facilitate identification, measure the voltage above each one, equal resistors in series must show the same voltage drop, so an altered resistor is discovered, most of the time it is the glue under the resistor , you have to remove and scrape the glue! | Lucas |

LED on but not turning on, voltage+b 118v, heating up q430 | Capacitor c419 without capacitance (plays the role of the horizontal driver transformer on TVs that use it) | After replacing the capacitor everything went back to normal | Lucas |
