TV turns on, backlight turns on and then turns off, won't turn on again. unplugging it after a while repeats the defect. | QM805 on power supply board - SMD NPN Transistor | Pardal-x | |

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 |
