Even after installing new LEDs, the LEDs do not light up, reversing only gives a pulse and trips. | New LEDs came with 6v. originals were 3v | Eliminate central bar by jumpering it (has no effect on the image). remove 2 2r2 resistors to reduce current from the LEDs. | Mau3000 |

TV turns on (button lights come on and has sound), but no image | Inverter transformer without power supply; I noticed that the ci ap4506geh was burning. fuse f301 was also blown. ATTENTION: you must remove the fuse from the board to measure its continuity! | Changing the ap4506geh and the f301 fuse (4a 125v) - if not available, adapt the common fuse by soldering two terminals. I lost a lot of time because the f301 on the board continued, but when I removed it I found that it was open. continuity regardless of the fuse occurs thanks to other components that connect to its track. | Cadu |

TV turns off by itself and standby LED blinks 6x. | Defect in the ci bd9397efv responsible for the backlight operation. In my case, I redid the connectors on the rulers, but the TV still activated protection. | Check the remaining voltage on the negative of the LED banks. the correct thing is to have between 0.8v and 1.5v left. Above that, the TV can trigger protection. If tsound is no defect in the rules, replace the ci. | rafaelmoraes99 |
