SA-AKX440
|
Doesn't start. It doesn't even light the panel. | Dz1000 diode shorted. | I replaced the dz1000 diode (code: b0jcpg000032 schottky barrier) with model sb140 (shottky found in a TV power supply with pfc). | R-Tec |

TC-14A04
|
TV doesn't turn on, standby LED lights up very weakly. | The 5v line on the standby was only 2v, as was the 3.3v line that comes out of the ic1201 regulator and powers the computer. | Zener diode d1140 (5.6v 0.5w) shorted, killing the 3.3v line that powers the computer. By replacing this diode, the TV turned on again. | Rgs011 |

Sometimes it turns on, and turns off completely out of nowsound, sometimes tsound is no sign of life. | Overprotection circuit being activated erroneously | Zener d7207 on the run, the voltage to activate the protection on the cathode must exceed 6.8v (zener voltage), but feeding with an external power supply, caused the base of the transistor that is connected to the anode of the diode to trigger with 5 volts. | Davi.sls |

|
Normal turns on 3 to 5 minutes... power supply switching... heating up the ic803 a lot | Dz804 de 18volts na base do q817 | I replaced the ic803 and it stopped heating up and switching the power supply (dz804 leaky zener) | Alextecnico |

|
TV turns on and off after a while, red LED flashes once | Pin 7 of the ci u101 inverter board must have 4.8v and it was having 1.7v, note that the LEDs were not defective as they were replaced and the defect still persisted. | Ci defective pin 7 killing the voltage! ci replace | Play back |

TC-29KL04
|
Turning itself off in less than 2 minutes | I noticed that the strw got very hot and went into protection, causing the power supply to stop, leaving the capacitor charged. I checked the entire power supply and when I removed the cooper, the ferrite was missing a piece at the bottom. | I removed the ferrite from another scrap transformer and repaired hers, the strw reduced the temperature and the TV no longer turned off. | Eliel Magno |
