Backlight disables after about 4 seconds | I noticed that it was only when tsound was no video signal. | But the solution was the same as that suggested by Fatec Electronics, that is, isolating tracks 2 and 3 of the flat connected to the p402 connector. | Chumbão |

No voltage on the power supply secondaries. | C803, 400V/220UF Open, R804 1K Open and PWM Generator IC (NCP1337P). | Replace the aforementioned components. (tec edfersom, varjota-ce) | Edfersom |

Turn on turn off | Burning diode code 36 = ss36 sms and regulator 54240, high supply, for the rest of this board I placed a 33k resistor on pin 1+vdd and pin 5 down sets the power supply to measure this voltage on this pin 1 giving 38.5v which had to be given in the scheme 32.5v to reduce this voltage I put a 10k smd resistor in place 7.5k it is close to a regulator u4 az431 - ae1 (r11) measure reduces it to 35.9v you cannot lower it to 32.5v the device does not turn on it has to be 35 .9v | Defect resolved, device did not return for assistance | Andre |

No image, with sound - it wasn't the open 22r resistor near the t201 - underneath the heatsink tsound was a burned smd capacitor, and it burned the 2 fets 30f133, (igbt) which can be substituted for the fgd4536 used in samsung tvs (plasma ) | Change two fets 30f133 = fdg4536 (samsung plasma) | VICTORINO | |

It has the normal +b, the LED is on but it doesn't turn on, it doesn't oscillate. | A silly cause, broken line between the fly back output and the transistor collector. check | Check continuity between fly back pin and transistor collector. | Luiz Carlos |

In a completely colorless channel, it only showed color in the osd. | Ci micro 7600 and eprom memory. (be careful, only turn on the TV after having replaced both, as if you only turn it on with the memory changed, the computer corrupts it again and the defect continues) | Replace the computer, and replace or burn the eprom.
