Vertical closed, both at the bottom and at the top, the screen is reduced, image in the middle of the screen | Change resistor r219, 390k, precision resistor, next to the processor. on pin 21 of the processor. | DJ PITUKA | |

Turns on, blue LED on, no image (black screen) | 3 defective capacitors c301 25v 820uf and fusistor f301 125v 3a LF (green) | Replace of the 3 mentioned capacitors and fusistor. Be careful, don't forget to replace the fusistor as its function on the board is to protect all spike lines. If it opened it is because the peak exceeded its thermal dissipation capacity, without it the board would have been damaged beyond repair. do not bypass by excluding the fuser from the diagram. | Igor Cruz Brilhantino |

Doesn't start | On the power supply board the blue cs809s capacitor had poor contact, it was loose | Resolder the cs809s capacitor! zero cost tv returned 100% of the budget made before 350 reais! suggestion, before spending this amount try to solve it like I did, I didn't spend 10 minutes | Anderson |

To reduce the voltage of the LEDs and consequently the current, replace the resistors r9163 and 9164 with just a 1ohm resistor (1r) | The LED bars were burning out. This TV is not that old and the LED bars are not easy to find. | I tested it with a 0.22 resistor, the current drops a lot, with 0.75 it also works, I put it at 1r, it was fine, good luck everyone. | Eronaldo (erontec) |
