Does not turn on or turns on from time to time | X500 and x501 crystals. After heating it turns on... | Replacing it... removing x501 from old cell phone cards, tsound are lots of them. x501 removed from tablet board, exactly 24mhz, they are a little bigger, but they fit perfectly... | cricascell |

The image is flashing, the backlight is flashing, if you notice the problem it will be due to the low 12v voltage. | In my case it was the v806 next to the 12v connector on the main board, it is npn and was open, just compare it with the ones next to it, they are the same reference. | fabiusmax | |

At 220 volts it even lights up the lamps and gives an image, at 110 the lamps blink a few times and the power supply shows error 11 (11 blinks). defect in the primary power supply pfc | Q6 smd transistor in the primary power supply open, did not feed the u1 approximately 16 volts. | Replacing u6 (It's a pnp transistor) | MIGUELTV |

The red and green standby LED oscillates and does not turn on or light up the screen LEDs | D16 diode shorted on the LED power supply, note: recurring defect, this diode works very hot, if you want to remedy the defect so as not to burn out again, use the sb560 diode, I found it on a buster 42 board, it works cold, if it is new it must be original. r the defect so as not to burn again use the sb560 diode, I used a 40 board | Digitronica | |

When turning on the TV tsound is sound but the image takes a long time to appear. | When connecting the TV, the output of Q2407 (Mosfet for Chanel) does not show 12V (panel power supply). the gate voltage determined by the resistive mesh r2441, r2442 and q2406 was around 11v, that is, very close to 12v, with tsound not being enough vgs to drive the mosfet. It was observed that the gate voltage slowly decreased to a value around 8.5v, causing the MOSFET to conduct and the presence of 12V on its drain, resulting in the TV image. as q2406 is responsible for the voltage value in the gate loop, it was replaced. | Replace q2406 (mmbt3904 manμFacturer nxp). | Valmir |

Turns on, aoc appears and backlight turns off, after changing led bars, defect started after 20 to 30 minutes of fc. | Measure on/off voltage of %v, if normal, see dim voltage, if less than 3.3 v. measure the resistance above c748, if it shows a short, disconnect the resistor r1837 that comes from the processor and which regulates the voltage bl adj that goes to the dim point of the power supply, which turns the backlight on and off. | Note: I did this solution, so as not to replace the entire main board, since the fault comes from the main processor, and as I had already replaced the bus, it would be unfeasible to also replace the polish on a model that was no longer in production. | Olibio - Eletrônica Estudier |
