It turns on normally, after a few seconds it makes a hissing noise from the speaker and turns off with a red LED. After that, it locks and just unplug it and plug it in for it to turn back on. | In my case, all the power supply capacitors were bad, and these following capacitors on the main board: c666, c612, c1155, c406, c833, c879, c875, c1118, c1128, c1110, c710, c711, c1129, | Replace all the capacitors above. After a day of work almost with an oscilloscope and thermal camera I managed to solve | Eletronica SV |

No image. normal sound. LEDs on. no avdd voltages (16v) on t-con. | Cd5 and cd6. c08 and c09. c01e c02 shorted. on t-con. I placed a 22uf x 50v electrolytic in place of 2 ceramic capacitors. l. Then all you have to do is receive R$600.00 for the repair. ozatec electronics. sarandi/paranÁ. 02/09/2023 2:32 pm. | OZATEC / ELETRONICA | |

Does not tune channels, searches faster than normal and does not find digital and analogue channels. | Ci of the faulty tuner, 3.3v arrived at the resistor, but at the other terminal tsound was only 1v. | Changing the IC, I removed it from a Samsung board that had a similar tuner, fortunately the IC was the same, after the replacement the TV started tuning channels again and the IC supply voltage remained at 3v at the output terminal of the resistor. | Lucas Eduardo |

Turns on, lights up green, gives a quick flash of LEDs and the LED stays red with an error of 6 blinks. | In my case I had a LED kit with cable and everything and I tested it, I was able to confirm that it wasn't LEDs, I also had a 40w655 main board and I tested it instead and it worked perfectly, even the power supply to the LEDs crashed, I thought it was strange, but the pwm must correct it as it "sees" the consumption of the LED kit and corrects it. | Changing the main board, I'm not trying to find out what it was...that's for another opportunity. | MIGUELTV |

TV with a wide black band on the left side of the screen, the tube oscillated and even got a little hot | After a lot of analysis, even after changing the tube I found a resistor, R712, near the flay back, missing solder on the terminal, in other words, one terminal was loose, I soldered it and broke it with a hug | G.G eletronica- otacilio 29-03-2023 | |
