It doesn't turn on, it doesn't light up the LEDs. | Note, don't be fooled, this model when we remove the cable that goes from the power supply to the main board, the LEDs don't light up like on other Samsungs, so it's very deceiving, to find out, you only have a main board to confirm. | Replace main board. | MIGUELTV |

Device showing protective message | The aic2 audio output integrated (tas5342a) was removed and the message did not appear, when installing a new integrated the message was displayed again. | All the gaps between the CI pins were scraped as tsound was a lot of carbonization on the plate due to the heating of the part. This scraping was done with the tip of tweezers and assisted by an electron microscope for good visualization. Once that was done, I put the ci back in and the device started working normally again. | José Luiz Enguer Pereira |
