When turned on, the screen flashes 3x, the green LED also flashes and then returns to stand by. | 3 defective LEDs. | Replacing the LEDs. I took the opportunity to lower the LED current. measurements on the ld2 connector pins 1 and 3: 55.5v, 328ma. pins 5 and 7: 84v, 327ma. I removed resistors r51, r52, r26 and r29 (all 12r). remained: ld2 connector pins 1 and 3: 52.6v, 212ma. pins 5 and 7: 79.2v, 211ma. | Eletrônica R-Tec |

TV doesn't turn on, or turns off by itself, or sometimes doesn't turn on and freezes. | Defect in the function keyboard PCI. pci is double sided, and the power button track was shorted to gnd. Loosen all components and test track impedance at x10. | Isolate the track close to the connector and close to the touch switch, and make a jumper with a very thin wire. | rafaelmoraes99 |

TV doesn't turn on, or turns off by itself, or sometimes doesn't turn on at all. | SMD touch key on the keyboard has poor functions, causing the TV to have intermittent defects. In my case it was the power key stuck closed, causing the TV to not turn on and remain frozen. | Changing bad touch keys. | rafaelmoraes99 |
