Pulsing power supply, turning off | I desoldered and resoldered capacitors and resistors around the ICP801 IC, I resoldered RP808 resistors and nearby resistors, I resoldered RP839 and nearby resistors, it seems that the glue under the resistors changes the resistance. | Marcelo | |

Standby LED off, voltages ok, display ok and blacklight ok | Check the board with touch buttons, usually the SMD capacitor C03 shorts out and protects the power supply, preventing the TV from turning on | Location of the smd capacitor: close to the single electrolytic capacitor on the board, to confirm and just leave the TV plugged in and notice it heating up or with a thermal camera if you don't have it, touch it, you can feel the capacitor heating up. | Luiz |

The LED turns on and goes out quickly when plugged in, but it doesn't light up the screen or start the TV. | Use a 1k resistor between pins ps-on 18 and stby 16 to arm the power supply and carry out the tests. (use a filament lamp in series to avoid further damaging the circuit) | When you notice the absence of 5vdc or 12vdc: replace photo couplers pc 801s, pc 802s, pc 803s and pc 804s if the 12vdc still does not come back, replace zdm853 (ka or tl431) | Luiz |

TV turns on but the backlight flashes or then goes out, the backlight does not remain on even if disconnected from the main PCI, in this model the normal thing is for the backlight to turn on as soon as the power supply is disconnected from the main | After excluding the possibility of a defect in the LED bus, check the voltage at the point in common between the components d9802, d9801 and q9802, a voltage well below 1.6 causes the backlight to trip, in the tests sound q9802 was removed from the circuit with this, the voltage returned to around 3v at this common point of the 3 components, this with the PCI disconnected from the main | Left without the q9802 | Direto no defeito |
