Turns on, then the image goes off and only the sound remains, with a flashlight you can see the image on the display. | Shorted LED bars, out of a total of 40 LEDs, 16 were shorted, brightness control MOSFET burned on the board, damaging the plastic protection above and below the power supply board! | Replace the shorted LEDs, or buy new bars! Replace the TF450 MOSFET (AOTF450L), replace it with a TF454 MOSFET, which despite its VDS being smaller, looks great! | Lucas |

Push power protection | At first it would be the STK outlet, but when I opened it I noticed that tsound was a very dry factory glue between c596 and c546, hiding r561 and r511. | I removed c596 and c546, cleaned the area and realized that r561 was open. I replaced r561 and r511 with 100Ω film resistors, following the service manual. | Rodrigo Lamego |

Does not turn on, LED blinks 9 times twice and returns to STBY. The 33ufx160v capacitor was exhausted, it was replaced but it didn't solve the problem. | After much searching, tsound was a small flaw in the soldering of the d807 diode which, after being redone, the TV started working again. | Carlão | |
