Backlight does not light up. | If the voltage at the output connector for the LEDs is above 100v, the board will be fine. If it has around 62v, the backlight circuit will be bad: if pin 1 of the CI drive ub1 has 12v (with the TV on), tsound is no need to remove qp411 or cb6. if pin 14 of ci ub1 has below 4.3v, remove cp9 and rb23. | If you have any questions and I can help, you can contact me on WhatsApp 82993677063 | Carlos Araújo 82 9 93677063 |

Changing the backlight and reducing the power supply | Continuing the previous tip; to reduce the backlight power supply directly on the power supply board, replace the smd resistor r619 (47k) with a 10k resistor. After that you will see a reduction of around 5v in each of the two backlight power outputs. | EC | |
