Turns on without functions, the bluetooth indicator just blinks. | C521 on pin 38 (internal reference voltage decoupling) of u501. | Replace capacitor c521 from 47μF to 1μF, when changing the reference, the commands work again as they are compared with the voltage on this pin. | Zener Serviço Técnico |

TV only turned on after several attempts and warming up. | Capacitor c130 - 100uf x 25v on the device's power supply board. | I replaced the c130 capacitor with the same capacitance. As I didn't have a 25v capacitor on my bench, I placed one with a higher voltage limit: 50v. This modification is not problematic, you just have to respect the minimum limit and place it equal or higher. | Villeneve Oliveira |

With audio without image | Burned out leds | 4 kits of LEDs were replaced, note: the bars were twisted, when turning on the TV the LEDs burned out, after many LED replaces I identified that the new bars, being parallel, were shorting out against the chassis, insulation was done with tape underneath from the bar the same thing resolved. | Dimerson Lima |
