LED was just blinking secondary power supply + pulsing it was only giving 70v dc | TV hand could oscillate due to lack of 103 v in the choper's secondary that goes to the horizontal output | In my case, it was just to replace the capacitors c825 of 47μF for 160 v and c 829 of 33μF for 160v and run to the hug, God and faithful | eletronica sto ant rj |

Dark screen, burning bar LEDs | This TV arrived at my workshop with the following defect, it turns on normally, it has sound, the image is half dark, I changed the LED bar, some LEDs burned out, I replaced it, I decided to check this defect, it was the display board wsound it takes the flat cable that feeds the LEDs, I found u901-max16814b in short and close to this ci to 4 smd mosfet transistor that releases a 12v voltage q905,q906,q907 and q908 bss123 - code sa they are leaking and short, I changed it, it didn't burn but the smd leds | Defect resolved | Andre |

Function key does not work menu and vol+ | This TV arrived at my workshop with the following defect, it turns on normally when the volume goes up, it doesn't increase, just press the vol key -, in the menu it also says the same problem, I checked the 3k3, 2k and 2.4k resistors are all tsound, all the keys smd touch devices are good, I checked the broken track, nothing, analyzing the schematic I heard a factory defect instead of the 3k3 smd resistor, it was supposed to be 1k, I decided to change the resistors near the menu touch key and vol+ smd 3k3 I put 1k, the volume worked increase and menu worked | Defect resolved | Carlos |
