It arrived on my bench with a burnt flyback and open r430, altered r227 and dry c889, replaced components. TV turned on with a blue screen and the image closed, found c305 altered and d901 shorted without characters | R430 r227 c889 c305 d901 flyback | All components replaced TV turned on perfectly | Eletrônica Lima pb |

Does not turn on the lamps | Model in which the power supply board is integrated with an inverter, if the 12v voltages and the on off pulse are normal, changing the circuit n701 ref.uba2072 in my case did the trick, I got it from another board. | Alberi F S | |

Nothing turns on, no stand by LED, 5v stand by power supply absent, | On the board next to the processor tsound is ic code n806. fr9889 (dc/dc converter) had voltage on terminal 2 (input) that comes from the main power supply and did not have 5v on terminal 3 (output) | Replacing the aforementioned ic n 806 only solves the problem. | Assolini BR |

The panel doesn't light up and the sound is noisy | The blacked-out panel was resolved by replacing r962 at the power supply, and the sound defect was missing a negative supply in the IC402 pre-amplifier IC, transistor at the power supply q953 c3205 toasted | After replacing the components, the solution was resolved. | Protec eletronica |

Without image, with sound. | I identified the open fuse f102 on the inverter board and a short to ground caused by some component on the right part of the board. By pure luck, the first component I removed for measurement was the one causing the problem. The smd 125v/7a fuse (f102) and the ci 4614b (q310) were replaced and everything worked again. | Bertinetti | |
