Turns on the logo and quickly turns off the backlight, leaving normal audio. | It trips due to burnt LED protection (open or shorted) or due to a defect on the inverter board protecting due to low voltage or high voltage on the LED bars. | On the inverter board, remove resistors r100 and r203, they are both close to the two oz99967, they are following pin 27 of it. | EC |

The TV does not turn on the power supply, pulsing with very low voltage, just the LED flashing green. | MOSFET QP4 short in the circuit that powers the LEDs was checked and the TV was ok | Reginaldo Alves | |
| LG |
RP44NA40PA

TV would arm for a few seconds and give audio and turn off | I loosened the cables from the cannon that is connected to the triplicator or capacitor block and nothing, then I released the one from the flyback, the flyback generated high voltage and the TV stayed on, of course with no image. | Replace the block 4410z a001p you can put it with the ending l which is the same. | Bardock Eletronica |

KDL-32R434A
|
Does not turn on stand by led off | The voltages present in the regulators 3.3v 2.5v and others the cause was the micro shorted u401 - mt5580gudi end bcsh has to be the same as this end if not, the tv doesn't work, i removed the bga soldering station everything was ok the tv worked | Defect resolved | Andrei |

The TV has a short IC201. check +b voltage with 190v | I checked the primary power supply and found the changed c610 to replace it and everything was fine. | Adaloton ms | |
| SONY |
KDL-32R434A
|
Does not turn on stand by led off | Measuring the power supply to the regulators, they were 0v, the defect was u705 and u706 - tps-54339 shorted, I changed the power supply, they returned to the regulators and the stand bay lit up, I turned on the TV, it worked perfectly | Defect resolved | Eletronica Hally |

Turns on the blue volume LED lights up, but the display does not turn off | On the front panel board the c11-104 =100k 50v ceramic short I replaced, which caused the short comes to the main board, very close to the photocoupler the 2 resistor changed and opened r152-330r smd and r153-2k2 smd, already on pin d14 - fr107, tsound is an open resistor r137 - 2r2 smd and q17 - mpsa92 in short, near this transistor r139 - 100r with smd leak, I replaced these components and the display started working again | Defect resolved | Eletronica Hally |
