Turns on and off stays on standby | Leaky capacitors at the power supply and burnt deflector coil | Deflector coil and power supply recap, as most of the capacitors are leaked or altered | |
| PHILCO |
PH1100

You know de santby and time | Electrolytic capacitors ce6, ce7, ce5, ce2, ce8, after the change it turned on but when it was connected the cooler again it tripped again, it was necessary to change the cooler | After mounting the board in place, tsound was no sound coming out, tsound was only output on the subwoofer, the diodes d5, d 22 and r250 were also found to be defective | Mitzko eletronica |

Red LED does not turn on, flashing continuously once | Short on the main board and the power supply board, causing the board to release 16v directly when disconnecting the power supply cable from the main board | Changing a ceramic capacitor close to the connector that receives the cable from the 16v line power supply. changing a transistor on the 16v line supply board, in my case the transistor was visibly blown. | ELETROSANROS |

Doesn't start | Defect in the power supply measure all voltages 0v porcelain resistor 1.8r 5w near the relay open, so this resistor opened it fuse + resistor I replaced it with another one resolved the voltages appeared | TV everything ok resolved | Andre |

Does not tune digital channels | Varicap in short 5bf6009 and ec40 1000uf 10v tufted, so I can't buy varicap doesn't sell, I decided to change the ts3b ver:1.2 board | Defect resolved digital channels everything works | Andre |

Does not turn on inoperative | Power supply that feeds the audio output with no voltage on the secondary stdby power supply ok oom 3.3v in my case checking all the capacitors tsound was no defect I took the main IC strx6759 from another device working and it still wasn't resouble I returned the original IC I did more tests and nothing solved, I checked all the strx6759 coupling smd components, they were all good, it took a lot of work lol | To solve this case, it was very simple. I remembered that I already got another sound device, which was LG, which used this same ci on the strx6759 power supply that powered the amplifier and it turned on, but without audio, as it did not have power on the amplifier board, good a The solution was to place a 10k resistor on pins 3e4 of the photocoupler pc5720 panasonic sound, which compares the power supply together with the ci tl431 in the lg sound the same procedure was done ok | rubertan |

TV doesn't turn on. stand by LED on, power supply without secondary voltages, only 5v stby. | I was going to change the power supply board, but I noticed several spots of oxidation. | Cold solder on the qm852 transistor close to the power supply connector. | Alexandre Oliveira |

No image, back light on | C202 on the display board. Pay attention because the first time I measured it did not present a short, however it had a low resistance. | Replaced it with another plate removed from a broken screen and it worked perfectly. It is very important to add another one and never leave it without a capacitor. | Mário Fernandes Testoni Junior |

I'm sound | The 35v power supply for the audio output is missing | Q901 (fet 8n80) in the power supply primary, and the photocoupler pc903 that monitors this voltage. | Baguatech |
