Turns on normally, no audio | Measure the voltages -39v +39v, which feeds the outputs, it is giving 0.2v, the cause was fuse f3 t6.3a 250v thermal open I changed the voltages, they normalized, so the cooler that cooled the power supply was not rotating 0.15a 12v I changed resolved. | Defect resolved | Andre |

TV turning on with no picture | Pfc voltage with 170v | I replaced the fan7530, but I used another compatible IC, the sem3040, so the voltage rose to 300v, but it didn't turn on the backlight, so looking at my colleagues' tips, I found a solution by placing a 4k7 resistor on pin 16 of the sem2006 to the on/off pin reverse the board connector, then the TV turned on the backlight and started working normally again, thanks for the tip from my friends! | Michael |
