Half of the screen was bright, the other half was dark. | Broken jumper on the power supply board | A Jumper at the mosfat output that controls one side of the LEDs has a jumper under the heat sink of the 2 diodes and 2 fats on the secondary, just reconnect the jumper and it works again, but even so you have to reduce the current of the LEDs on this model . | Eletrônica ATM |

Completely stopped, not even standby | Screen drive board with shorted capacitor c203, however when trying to turn it on, the board was also inoperative, when checking it was found that two 13v fuses that came from the power supply were burnt, after replace them the TV started working again with shorted ceramic capacitor c203 | Replacement of c203 on the screen drive board and replace of fuses at the main 13v input, coming from the power supply. | Cosme |

The LEDs don't light up | TV arrived with sound and no picture, I immediately imagined it was the LEDs! I opened the display and the LEDs were 100%! Tsound was no voltage to power the LEDs! Voltage arrived at the SLC5013R ci (ic1701_ad) responsible for the voltage of the LEDs. | Replacing the SLC5013R ci | Rafael Sena |

It doesn't turn on, and when it does, it turns off right away. | Transistor do POWER ON. | To test if the regulators are good, just release the Power On wire from the harness and see if the regulators on the board are working, if everything is working, without the power on connected the TV has to turn on, if it turns on and works perfectly, You have to analyze if it is not the Power On command transistor, tsound is one on the power supply and tsound is one on the main one, in my case, it was the bad main one, it is in position Q203, between the HDMI and the Optical Audio, just replace it and receive the Pix. | Eletrônica ATM |
