I have a LG 32ld320-za TV. My problem is that after connecting the cable to the TV from the antenna, the TV does not search for any channels, I will add that it has a built-in MPEG-4 decoder. I have already checked by connecting different antennas to the TV, the problem is still the same, I will add that the antennas were set well. The TV currently operates with a separate DVB-T decoder.
