Turns off after a short time on | In my case I changed all the capacitors and it didn't solve the problem! The solution was to change the tny277pn | Replace tny277pn I put a tny178pn and it worked rodrigo cofferi | Rodrigo cofferi |

Dead tv. does not turn on stand-by LED | Tsound was no voltage coming to the main capacitor. relay at current input with broken terminals (relay lying on the board next to the varistor) | I couldn't find another to replace it, so I scraped off the broken terminals and soldered them back in place. | George Luís |

Snoring when calling | Symptom appears to be a burnt transistor, but look at ci 4558 on the amplifier board. If it is burnt out or tsound is a lack of voltage of 15 volts, the transistors are all altered, triggering the current. | Alpha Eletronica Alvorada RS | |

Turns on but tsound is no sound | No power supply to the sound output, the defect was the mosfet u6 inputting 12v, outputting 1.2v | Eletrônica Mirage | |

TV turns on black light, image appears and turns off | The TV turns on, the LEDs turn on, the image appears, it remains on with audio, but tsound is no image and the LEDs turn off. turning off the v-com flat, the LEDs remain on. short on v-com | Underneath the coil l1, the zener diode was open, causing the capacitor c224 line to be shorted. remove the zenner and tv worked | Leandro JLTEC |

After changing the LEDs I noticed a serrated image on the outlines of the writing and images and a simple vertically serrated scratch in the extreme right corner looking from the front. | I arrived to imagine if the screen (v390hj5-xcpe1), but as I had the main test board it was faulty, a defect on the main board. | I didn't look for the defect, as I bought the TV to be dismantled due to this, but sound's a tip not to think that it's a display defect. | MIGUELTV |

Turns on normally, after a few minutes of operation, turns off, red LED flashes 14x | After power supply vitrification, I observed: at the moment it works, power supply with 16v and 24v, normal. when it is defective, 16v power supply, with 13.4 and changing. | General resoldering at the power supply solved the problem. | Arock |

Negative type image after changing the main PCI. | The defect is caused by having 2 types of screens for the same board, solution, remove or because the r492 resistor value 0relay is a jumper, then the image returns to normal | PLAY BACK | |

The TV would turn on the key, the power LED would light up for 5 seconds and then turn off and the LED would no longer light up | I tested all the capacitors on the primary power supply and they all tested good on the capacitance, but I was suspicious of the electrolytic capacitor c886 0.47ufx50v and I replaced it and it worked immediately. | Replace electrolytic capacitor 0.47μFx50v c886 | Fabricio lima |

Turns on without image, with sound and backlight, responding to commands. | Resistance of 0.02 across several capacitors on the v-con board. I had to remove them one by one to check which one was shorted. | In my case the short was only on CD2. replace and jump for joy. | World TV |

If you unplug the power cord and plug it back in, it becomes inoperative. | Tsound was an overload on the electrical network and the device would work if the primary power supply capacitors were discharged. Also if it turned off using the remote control, tsound was no problem but if you unplugged it, it wouldn't even turn on the stand by | Replace the power supply oscillator ci | Hélio Eletrônica |
