When it was cold, it would turn on normally when it got hot, it would turn off and the green LED would flash, and before it turned off, if you unplugged it and turned it on again, it wouldn't turn on immediately. | I thought it was a power supply, I even changed the board because the symptoms were from a power supply but it was BGA | I did reballing, changing the balls that are underneath the processor | Edivan Eletrônica |

Turning off backlight after a few minutes | LED defect | To be sure, I disconnected shut resistors, r31, r33, in parallel, at the foot of transistors q1, q2, and inserted a 0.22Ω resistor, backlight remained on and I was able to give a quote for sure | Claudio Jorge Eckert Junior |

TV not turned on, not even stand by lights up | In this case it was not a broken track, the defect was in the two electrolytic capicitors, cm859 and cm856 | The 13v voltage was varying, just replace the capacitors and run for the hug | Celio |

Device is not bivolt (110v or 220v without key) | But it has a bivolt transformer (0v 110v 220v) and can be adapted, don't forget to mark the correct voltage on the box and delete the voltage that is no longer available. | ||

Output only outputs the same signal as the input, as if the power was turned off, check with continuity test | 20x10x12mm 8-pin relay, burnt 24v coil. It was designed to send 30v to the 24v relay coil. If possible, adapt it with the lm7824 regulator. | Replace the 2 24v relays (and adapt the lm7824 regulator or place a compatible series resistor, or a zener diode in series to lower it from 30v to close to 24v) | |

The TV turns on, the LEDs turn on, tsound is no video, it seems like tsound is a defect in the main or display | As I have already obtained several tips on this site as well as on You Tube, I am passing this on to my professional colleagues: first check if tsound is a ci on the tcon with high heating, if so, turn off the flat in my case on the left side of the vcon then see if it has stopped the high heating in the ci, if so go to vcon and see the c107 smd in short it will solve it but it could be others that are on the same line in parallel, hugs. | Digitronica | |

Display does not light up. | Q15 = c3205 toasted, d58 and d59 both 20v zener shorted, r161 4.7 changed. | As I don't have the original components, q15 I placed the c2328a (in the schematic it is c3940a), d58 and d59 20v zener I placed two 18v zeners, as the sound came from another technician (or curious person), r161 of 4.7r (in the schematic) tsound was been replaced by an 82k. | renne |

The TV would turn on oscillating normally, but before the image appeared it would simply turn off and the LED would blink. | Loose flyback ferrite. | Put a shim on it or find a way to fix it, or if you prefer, replace the flyback. | Tiago C. Neves |
