Only on standby. | Burnt fly back bsc25-0233y can't be found anywsound. | Replacing the original fly back with a bsc25-0230z, changing capacitor c453 from 272j/1600v to 562j/1600v and also c457 from 153j/1600v to 183j/1600v and increasing the vertical IC and horizontal output heatsinks. | Max Andadra |

Backlight does not come on after changing the LEDs | Changing the 2 LED bars | I replaced the LEDs and went to test the TV! As I didn't imagine, this TV doesn't turn on the LEDs if the screen (display) is not connected! the power supply voltage for the LEDs rises to 315v, the normal operating voltage is 180v! So don't be fooled, you replaced the LEDs, being of good quality, just set up the TV and run for the hug! | Rafael Sena |

Turning on and off continuously (before just st-by, it didn't turn on) | Replaces dc/dc converters n802 and n801 - fr9889 | After changing the ci n802 and n801, both dc-dc converters, one of them accidentally ripped out a 10k smd capacitor (c803), which is between pin 01 and pin 03 of the n802, putting another capacitor in place it started working normally again | |

LED current reduction | To reduce the current tsound are two resistors connected to pin 2 of the IC LED driver, one with 91k and one with 39k, just remove the 91k | Above tsound is a reduction tip but it is wrong the pin mentioned is the din pin, it is not reduced on the din pin but on the iset pin of the ci which is the current monitor pin | Ariel Santos |

Blurry image, without definition. | Blurred image, at first I thought it was a defect in the ymain, but after changing it, this was not confirmed. Checking the zmain, I checked the 3r resistor r4063 (when I measured the voltage on it, it was around 5v, normal 15v) open, done the Change the image back to normal. | TECCENTER | |

Inverted image after changing the main board. | Wrong signal resistors lvds option | Even changing the display in the menu, the image is not corrected, I only managed to correct it by checking on the old board a difference in the resistors below in the lvds connector on the main board, in my case the r4140 was removed and the 1k r4143 was added, also check the r4146 | Davi.sls |

Does not turn on, voltage vs/va rises and falls slowly. | The TV was defective in the rjp63k2, cap. polyester 330kv and no fgd4536, smd. I changed everything, re-welded the y, z and power supply, but it still wouldn't work. | After racking my brain for a day, I'm going to give the tip that Pablo Plasma from Mexico gave in a video, about an SF10A400H SMD diode, if on the diode scale it's measuring below .460, replace it because it's leaking. | World TV - Sorocaba |

Stop without stand by, normal power supply | On the main board close to the ic806 1g1m power supply connector, tsound was a short in the nearby capacitors. | Arimateia |
