The TV takes a while to turn on and when it turns on, black bands appear on the side and a white band at the top of the screen and the + b is at 95v | The cause of the defect is a 4.7 precision resistor in position r844 | After changing it, the TV works perfectly again. | AssisTec - Manari-PE |

Does not turn on +b voltage goes to 115 and then drops to 66v (stand-by) if you release the photocoupler it stays the same, all components associated with these defects tested and good... | Simply take out the d861 on the primary side of the power supply. Do not replace for another and do not measure. | Do the procedure and leave it to test. (tec. edfersom varjota-ce) | Edfersom |

Does not accept functions/commands only from the remote control, the TV keyboard works normally | When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v. | Defect in ic1201, after taking all measurements of IR line components. The only thing left was the ic1201 as a defect, after changing the ic, the IR voltage stabilized at 3v3 and started accepting commands via the remote control again. | EC |

Sem backlight, as normal | At first we thought it was a burnt out backlight, but in the end it was working 100%, the defect was caused by a smd 334 (330k) resistor that is positioned right next to the backlight power plug, it is between the cn1401 plug and the fet q1401. the resistor in question was damaged, just change it. | Check the resistor in question and replace it if its characteristics have replaced. | EC |
