Inverter protection | Wear of the LCD lamps. | Transistor q1 is responsible for the protection circuit when the lack of phase in reverse (shorted lamp or inoperative output) or one of the phases is uneven (lamp wear) and a potential direction is generated and q1 is activated, well I put a resistor 10k from the collector of this transistor to ground and the protection circuit stopped activating, when the collector raised the voltage above 1.0vdc the protection was activated, with this resistor the collector remained stable at 0.2vdc, hence the protection circuit was deceived | Edson Caeté |

Turns on very weak and grainy image | Fet 9n25 on the y-sus almost at the tip of the board, tsound are two but only one was bad. I replaced it with the smk0460 and it was fine. | Sylvox | |

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 |
