3.1.5.2. Digital TV board
It’s the circuit board which contains the decoder and all the components needed to receive and
manage the aerial antenna signal.
Directly to this board it is connected the antenna cable. Here it’s signal is amplified, divided
between the video and audio signal, codified by the decoder and managed by the tuner which
allows to tune the TV and radio channels.
Due to its positioning on the rear display support, just over the AUX input board, it is also used as a
“bridge” for the signals between AUX input board and iPod docking station, and CPU board.
