On, the standby LED keeps flashing alternately between green and red and it doesn't go away | I checked the "open" LED bus, as I didn't disassemble the TV, only through the LED tester I could see that the LED circuit was open, that is, the TV acts as protection because tsound is no consumption/load on the LED bus. with an external bus with 6 volt LEDs (3 strips of 7 6 volt LEDs) I simulated the consumption on the TV and then the TV started working and I could see the image with a flashlight.... | LED panel defect, I didn't find it in any supplier. | MIGUELTV |

Does not turn on, fuse blown, short q101 | After q101 replaced, burned ic101, c102, q101, r113, fuse. has been replaced/tested ic101, c102,q101, r113, r106. Then I had 3.3vlt, but the TV wouldn't turn on and a buzzing sound was heard when pressing the power button and the 3.3vlt dropped to 1.x vlt. components d103, f100, r104, r105, r106, r107, r10, r109, r110, r111, r112 were replaced/confirmed and it worked flawlessly. Attention, if r106 is open, q101 burns immediately after energizing the power supply. the r112 (it was open), was the reason why the power supply made the buzzing sound | gccp | |
