Turns on has audio but the LEDs do not light up | Test the 64 volt bus for each one, if tsound is no 5v on pin 1 of u4, replace the z9 with a 6v2 zener, then if it works, reduce the current by removing r116 and r 118 | Rodrigo cofferi | Rodrigo cofferi |

All white image | Ceramic capacitor cp8 on the v.con board | Take it out and it will work, but if you want to replace it, it's better for the same value but you have to look at the schematic | Eletrônica Júnior |

When connected to the socket, it turns on by itself for 2 seconds and turns off, leaving only the standby LED on. | Replace ci memory position u402 | In my case tsound was no point in re-recording the same, I had to re-record another ci and put it in its place, obs original ci the numbering starts with 25q64 but you can put 25q32 which works too | Marcos Cavalheiro |

TV restarts 3 times and turns off with the LED flashing 6 times. | The bd9397efv c.i was arming the protection...I changed the leds and nothing, I cleaned the leds and nothing, I changed the c.i itself and nothing, I changed the 39x50 capacitor and nothing too...so what I did was the following... pin 31 of the ic 9001 is the timer protection, and on this pin tsound is a capacitor, I removed it and put a 10k resistor to disable its protection... and the TV worked without turning it off again, I left the TV in test for 15 and without presenting the defect. | Put a 10k resistor on pin 31 of the ic9001 and remove the capacitor on this pin 31...tv ok | eletronica cachoeira |

Turning off after a while | Complete resoldering of PCBs y, z and power supply was carried out. The problem was resolved and another one appeared. 1 fixed horizontal line on the screen. | Flat bμFfet cleaner next to the line. not resolved. cleaning of the 3 flats close to the line was carried out and it was resolved. good luck ! | |

Switching off after 10.5 minutes, sometimes in less time | 12v power supply on ic32 (dda001ag) being cut off | Just replace the ic53 (photo-coupler) obs. even if you do well on the test | Deo Eletrônica 8198904-0186 |

It turns on, tsound is sound, it generates an image, but the lamps do not light up and it does not generate an error code. | No mainboard dim voltage. | Inject 2.8 v in series with a 1k resistor on pin 10 of the bd9247 through the existing resistor in the line. the 2.8v is at the power supply | Jadson G Nascimento |

Sometimes it cuts the image and only audio remains! but always with the LEDs on! on the t-com board, if the FET300 IC heats up, it releases 17v and the image comes back, sometimes shaking the right side, change the t-com | Sometimes with an image, sometimes not! but always with the LEDs on! changing the t-com | Rodrigo cofferi | |

TV doesn't turn on standby, it's kind of orange (neither green nor red) | Ci v802 right next to the capacitor on the main board! | I took this same model and same position from a scrap yard (it has to be v802) ready, the TV was perfect! | Eletrônica Manauara |
