Roasting high capacitor close to the inverter pin CN12 (ck15b) | Defective lamps. | Remove the ck15b capacitor from the board as this will reduce the voltage on the lamps and it will work again. However, I recommend changing the bulbs if you can. In my case, as I hadn't left it like that, I made the customer aware of the problem. TV works for 2 days sound with me connected directly and it didn't work any better. | Romulo |

Turns off randomly or doesn't turn on at all, the power on sign appears and disappears. By turning off the main board, the power supply works and turns on the backlight | 13v from the power supply was a little low, 11.5v. smd capacitor cm870, works together with the um801 (ka431), which regulates the 13v. was with, escape. | Replacing the capacitor, checking the regulatory circuit. | André |

Does not turn on at 220 volts, the standby LED flashes and does not turn on. When connected to 127 volts, everything works normally, has all voltages and turns on normally. | When plugging in before activating the remote control, the voltages after the dp804 diode fluctuate. | Capacitor cp815 (150μF/ 450v) with slight swelling, replaced and everything worked perfectly. | CDS_DIAS |

The television turns on, activates the LEDs, turns off and the LED indicator starts blinking. blinks 5 times and pauses. blinks again 5 times | Defect caused by a capacitor in the v-con of the equipment screen. in my case it was the cd9, but tsound are 4 capacitors next to each other. Use the voltmeter and take the measurements correctly. one or more of these may be shorted, causing the defect | Simply removing it can eliminate the problem. Of course, if the colleague has the capacitors in stock, he can replace them | Eletrotécnica São Rafael |

Stuck in standby | It seemed to be a defect but it wasn't, it was a remote control that wasn't original and, when turned off by it, the TV went into standby and didn't come out again. The procedure was carried out by holding down vol+ and then turning on the main switch until the TV turned on, then with Using the original control, it turned off and on again and the problem was resolved | Here's a tip: control for this TV model only the original | PATRICK ELETRÔNICA |

Power supply with very high voltage caused sound outputs to burn out | R 919 with broken pin in front of the str, ic 904 sn431, the two sound outputs tas5612la | After changing the components, tsound was no sound and it turned off after 30 seconds, so I analyzed the circuit and discovered that the q704 was open, tsound was no 12v on the emitter that goes to the outputs, the replace was made and resolved | PATRICK ELETRÔNICA |
