Red LED turns on, turns green but without sound and image, when disconnected from the socket, it took a while to turn off, that is, denoting low consumption, power power supply stopped. | Short on t-com board | After hitting my head, and removing the protection that caused the power supply to trip due to overcurrent of 12v, the t-com fuse opened, which made the diagnosis easier, as the TV started to turn on the BL, but with a washed screen. | Davi.sls |
