Turning off | How to test LED power supply and panel | For testing LED panel, and testing the power supplys. Remove the cable that powers the main board from the side of the main board, insert a 1k resistance between the ps-on and the 5.2v. with this the pfc that was at 180v goes to pfc-dc 380v. the 12v dc appears and the LED panel will light up | Rogério V.Campos |

Does not turn on standby, relay knocking does not light the LEDs and kills the voltages that go to the main board, giving the false impression that the defect is the main board wi-fi module or LED bar | Resolder the power supply board and check for broken tracks on the printed circuit using a magnifying glass or microscope. In my case, tsound were 2 broken tracks, like a micro crack, almost imperceptible with the magnifying glass, but which proved to be broken in the continuity test. | Resolder the entire power supply board and correct possible broken tracks | Melquisedeque Campinas SP 019988377105 |
