Power supply problemThe problem was in the infra sensor (7680), more precisely in pin 2, which was leaking and therefore took the voltage down by 5 volts (5vd). It took work, but this made the defect more interesting. who knew the sensor!

Just sprinklesWhen trying to change channels, only the channel indication (OSD) appeared and no image or sound. When trying to auto tune, the entire procedure was carried out without any channel being detected or memorized. checking the tuner and its peripherals, I found r3009 (180Ω) open. His replacement brought normality to TV.
