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 |

It would turn on, then the image would flash about 2-3 times, the TV would disarm and the red standby LED would blink once | I thought it was the LED, I replaced the bar, the problem continued, I checked the SMD fet on the power supply near the LED output, tsound was a bad cold solder, I resoldered it and it worked normally again | Lucas | |

At 220v it turns off when changing channels or with an image and the LED flashes 1x | 1 defect the glue conducts from the dz7207 of 6.8v causing q7203 to conduct preventing the IC 7201 from oscillating and we do not have 390v in the c7212 after solving this second defect turns on the TV power supply pfc everything works and the backlight blinks 2 times and then turns off and led flashes 1x this defect was resolved by changing the two inverter transformers | Measurements of the defective inverter transformer at 1.4Ω/2.72 mh on both outputs 1333Ω/ 1000 mh measurements of the scrap transformer but which worked at 1.4Ω/2.24 mh and out 1342Ω/ 842 mh tested with esr02 pro | BRUSKE 2019 |
