Audio only. | LED bars with open LED. | I removed the rb840 inverter resistor (4r7) in a previous repair. but returned in 2 weeks with problems with the LED bars. I replaced the rb837 resistor (3r) with a 3r3 one. The measurements were 61.7v and 248ma, it was 58.7v and 168ma. I hope tsound is no return. | Eletrônica R-Tec |

Intermittent, sometimes it turns on normally, other times it turns on a squeaky sound and goes into protection! | Altered zd904 diode, in the test it may appear as normal! | Replace without measuring! | Doremilton |

When plugging into the socket, the standby LED flashes 3 times, when activating the PW, the green LED lights up and then the red LED flashes again, giving 7 beeps. | Circuit inverts 3v3 and 1v1, tsound was no voltage, it is next to the flet cable that goes to t-com | Check if 12v is coming. my fusistor case open. | Naldo Lima |

Tsound is an image but no sound, the sound is only available in AV mode and not available in TV mode. | I changed the capacitors upholstery c833 and the others near it resistors diodes but it stayed the same way I saw the voltages were giving 12 volts arriving at the ci 7266 amplifier I put sound signals to see if the ci was amplifying pins 4 and 12 and it was yes I put them in the micro was also yes, until the amplifier I changed the micro processor and nothing | My solution that solved it was the epron ic 202 that solved it | Parente maia |

Audio only. | LED bars with many shorted LEDs and one open. | I replaced the LED bars. I lowered the inverter current to avoid return. I added another resistor 0r47 in series to r9830. measurements went from 453ma (in maximum backlight) to 371ma. | Eletrônica R-Tec |

This TV arrived in the electronics, it turns on with a sizzling and surper power power supply, heating up the 5563 coil and the screen sparkles and the image blinks and wants to close. | C2564,c2405 eo ic7515 | Replace the c2405 and c2564 of 47μF250v and the coupled photo replace without measuring and that's it, the TV will work normally. God be praised! | Sinailson furtado |

Turns it on, writes philco and between 12 and 15 seconds the TV turns off the philco and has a dark screen, but the LEDs are on and it turns off completely and goes into stand-by. If you press power it accepts and does it all over again. | As the manufacturer informs, this symptom is related to the LEDs, but to my surprise I risked updating it, which I downloaded from the website itself and the TV was perfect. detail that if it was an LED, when disconnecting pin 4 (fail) of the cable that goes into the LED drive board, the TV was supposed to work if it was a defective LED and actually the TV, even with the fail turned off, did the same, it turned off afterwards 15 seconds....so that's why I risked the update | Update software. | MIGUELTV |
