When activating the power key it remained on standby and the LED accessed but activated the channel or on the control itself, the LED turned off but turned on | Q7461 and q7463 were broken when changing them, it continued without turning on, they receive 13 volt voltage from 2 places of the power supply and the flyback after it started working, I noticed that r3493 of 6.8Ω was toast, when changing it I verified that only Tsound was voltage at the power supply output (main aux.) but it didn't reach the transistors following the line I found an SMD diode leaking d6464 when changing it the TV started working normally again | José Gusmão | |

Burning the horizontal outlet | Resolved after changing the output and the c2455, we found that the c 2455 47mf was ok in the test, but with an oscillograph it showed a big difference in the waveform between its two ends, we changed it and solved the defect. | bf.colatino | |

Device does not work or stops working after remaining in standby. | This problem may be caused by a possible short in transistor 7902, in this case, in addition to changing the transistor, the following items must be replaced: position 5930 from 100uh to 100r and position 3916 from 2k2 to 22k | ||

It turns on and off immediately, but no image, dark screen.. | Diode d 6681, with leakage...so the voltage at pin 50 of the ic7200 remains at 5v, blocking the video signal and not coming out. | Replace of the same .d 6681 .. | house eletronica |

It doesn't turn on, it makes a strong hiss, and the LED goes off and on as if it were working, but not on high | 7605 transistor, photocoupler and tea1620 | The 7605 bc627 transistor was found to be broken, as a result, the device turned on but the hiss persisted. Then the +bs of the power supply was found to be low on the 6535 and 6536 diodes practically doubled, so it was just a matter of replacing the tea1620 and photocoupler and moving on. | Eletroademar |

No image | Dark screen - no image or progressive active on dvd = - check resistor 3347 (open) and diode 6343 (8v2 zener) changed, when this occurs the led blinks 12x and increasing g2 the return lines appear, the sound appears normal, measure blk (approx. 4v) if not replace the diode | Check resistor 3404 | alacyte |
