Red standby LED on, does not turn on. | Probable leak in one of the fets q3 or q5 on the main board. | Check the fets on the main board q3 and q5, on the collector pin of q3 tsound must be 12v to ground, on the collector pin of q5 tsound must be 5v to ground. | EC |

No image, inverted or split image | Service mode | Type with the TV on, type on the remote control: 062598+menu+option code, in my case it was 463 (this code is on the back cover of the TV, next to an image of the display, in the upper corner of the label) then, TV will turn off, wait a few seconds and turn on the TV! | RAFAEL SENA |

The power comes on and the lamps go out. | One of the 8 transformers on the inverter board with secondary resistance changed to 13k wsound it should have been 1.1k | Replace the 80gl32t-24-dn transformer, easily found on the internet. | mfelipe |

Turns on with sound and image. Turns off in minutes, leaving the audio. | Disassembling the TV, tsound were several LEDs with problems. I acquired the new bars, these come with 60 LEDs in each bar, being a little smaller than the original. When installing the set on the support, do not leave space between the bars. Carefully remove them from the ends of the acrylic plate with the help of a saw enough to make a perfect fit between the bars. It's perfect. | gesuino | |

Turns on red LED standby. Press the button to turn it on, the LED turns blue, without video and audio, a few seconds later it turns red, flashing. | Check the power supply f501, open. in my case it opened because q707 was shorted. | Replace q707, f501. I tried using gold fet, it didn't work, it only works with the original (k3868) | arock |

TV turns on! The green LED lights up normally and obeys the remote control commands. but it generates neither 12 nor 24 volts. 5v and normal staby. back light flashes. | Always be suspicious of the pfc power supply, in my case it was resolved by resolving this in the pfc stage | Resolder the entire pfc circuit. success to all | Elizeu |
