Blue screen, wouldn't stay on | Defect in the flyback, and in the rgb board | I replaced the capacitor behind the flyback (22μF/250v) and the resistance on the side (3.9Ω) and lowered the brightness level of the flyback to be able to leave it on (it turned off when the brightness was exposed) then the screen was blue without characters no image, only blue, 18kΩ/3w resistor (which takes the color blue) was open, replaced it and it was fine | Dvid Técnico |

Without image, with sound. Dark screen, backlight off. | Burnt out bar LEDs. Philco ph39n91dsgwa television. without image, background shadow can be seen when external lighting is applied. burned out LEDs. replacement of all 40, for model 2835 3v. replacement of the (backlight voltage before 65 vc) rw 819 0r50 by 2r20 (current voltage 60 vc) to extend the useful life of the bus. | Giovani Pires Bitencourt | |

Does not come out of standby | I replaced the ci l6599d, however, the TV still didn't turn on. After researching, I realized that the l407 coil (on the main board next to the connector) had glue on top, disturbing the contact. After warming up the point, the TV worked normally. | NiloTech | |

Just updating the previous tip about the missing sound symptom, it is also necessary to add jumpers j806, j807 and replace r208 with a jumper. | Resistor r804 controls the attenuation of the audio signal, the value can be changed for adjustment. | Edfersom | |

TV does not turn on, relay activates and disarms then, red STBY LED flashes 4x and repeats. | After setting up the power supply on the bench and all the voltages appeared. but when connecting the main board it killed the 12v voltage. | SMD ceramic capacitor shorted to ground on the 12v line connected to pin 3 of the IC4051. I removed it and the TV started working again. | Jeferson |

Burning leds | Install new bar | Direct recommendation from samsung! 50nu7100 in models 49, 50, 55, 58 and 65 uses the same power supply; replace the 3 capacitors cm861, cm862 and cm863; replace the 2 resistors r9101 and r9201 from 1.7r to around 3.6r (models 49 and 50). in other models, respect the voltage of 5.6v per LED; derlei brancher • 08:55 db, that is, for this model it would be around 106v for each stage of the bar containing 19 LEDs! | Joao Bosco Sorocaba |
