Blurred image, increasing brightness gives shadow to the image | Dry electrolytic capacitors | C11 and c12 of 220μF/25v, c22 of 10μF/50v on the inverter and c217 of 220μF/25v on the power supply | eletronica fernandes-to |

TV without sound and LED image activates Note: after several attempts, the TV returns to working normally. When turned off for a long period of time, the defect appears again. | C862 2.2mf changed | jorge luiz mantini | |

TV with vertical closed turning off 8817 | Well guys, this defect was a tough nut to crack, I put in a brand new vertical, nothing, check all the resistors, nothing, I changed the yoke, nothing, well the defect was the d301 diode, which was altered, I tested the multimeter, it looked good, but when measuring with it on the board, it was open | D301 replace close to vertical | marcos melo cascavel ceara |

The device turns on, the display lights up and then turns off spontaneously, activating the protection. | C30/ c31/ c32, approximate voltage value across the capacitors, c30 15v/ c31 19v/ c32 19v. | Check the inverter circuit, in the protection stage, if the capacitors are shorted; c30/ c31 /c32 / 100kpf. To turn off the protection, it short-circuits the collector and emitter of transistor q9, and damages whether the device works normally. | xmichaelx |

Display without video (all white screen) and normal audio. | Shameless/D40/Saah0/Saats | When they noticed on LCD televisions models LC 15/2010z, display system without video, completely white screen and normal audio, located on the main PCI a/d. check: u27/d40/c370/c369, detected most frequently (d40) with leak. if the u27 regulator voltage was below 9vdc: completely white LCD screen. | xmichaelx |

No contrast, brightness and very dark colors. | The defect was the ceramic capacitor c 902 on the tube plate (102 k / 2000v). | I resoldered the entire tube plate, but that didn't solve the problem. measure the voltages on the transistor collectors, they were normal. the voltage on g2 was low, the capacitor was killing the voltage on g2. replace it and the TV returns to normal. | Júnior/Maceió-Al |

When turning on the TV, the LED lights up for approximately 5 seconds and then turns off. After this procedure once, it no longer lights up, only after a few minutes. I tested and replaced all c3209, fly back, power supply capacitors, no solution. | I only solved the problem by replacing the stv9302 vertical output. obs. "I used tda9302 and it worked perfectly." | Carlos Guerra | |
