PC/YPbPr Audio Inputs4. are used for connecting audio signals of a PC or a device that connects to the
TV via YPbPr. Connect the PC audio cable between the AUDIO INPUTS on the TV and audio output
of your PC to enable PC audio. Connect the audio cable between AUDIO INPUTS on the TV and audio
outputs of your device to enable component audio.
Subwoofer Out5. is for connecting an external, active subwoofer to the set to give a much deeper bass
effect. Use an appropriate RCA cable to connect the set to a subwoofer unit.
S/PDIF Digital Out6. outputs digital audio signals of the currently watched source.
Use a digital optic cable to transfer audio signals to a device that has S/PDIF input.
RF Input7. connects to an aerial or cable system.
Note that if you use a decoder or a media recorder, you should connect the aerial cable through the
device to the television with an appropriate antenna cable, as shown in the illustration in the following
pages.
HDMI 3: HDMI Input8.
HDMI 2: HDMI Input9.
HDMI 1: HDMI Input10.
HDMI Inputs are for connecting a device that has an HDMI socket. Your LCD TV is capable of
displaying High De nition pictures from devices such as a High De nition Satellite Receiver or DVD
Player. These devices must be connected via the HDMI sockets or Component Socket. These sockets
can accept either 720p or 1080p (optional) signals. No sound connection is needed for an HDMI to
HDMI connection.
PC Input11. is for connecting a personal computer to the TV set.
Connect the PC cable between the PC INPUT on the TV and the PC output on your PC
Ethernet input (for service).12.
Viewing the Connections - Side Connectors
CI Slot is used for inserting a CI card. A CI card allows you to view all the channels that you subscribe 1.
to. For more information, see “Conditional Access” section.
USB Inputs. 2.
Note that programme recording feature is available via these USB inputs. You can connect external
hard disk drives to this input.
Side HDMI Input (HDMI 4) is for connecting a device that has an HDMI socket.3.
Headphone jack is used for connecting an external headphone to the system. Connect 4.
to the HEADPHONE jack to listen to the TV from headphones (optional).
Side audio-video connection5. input is used for connecting video and audio signals
of external devices. To make a video connection, you must use the supplied AV
connection cable for enabling connection. First, plug singular jack of the cable to the
TV’s Side AV socket. Afterwards, insert your video cable’s (not supplied) connector into
the YELLOW input (located on the plural side) of the supplied AV connection cable.
Colours of the connected jacks should match.
To enable audio connection, you must use RED and WHITE inputs of the side AV
connection cable. Afterwards, insert your device’s audio cable’s connectors into
the RED and WHITE jack of the supplied side AV connection cable. Colours of the
connected jacks should match.
Note: You should use audio inputs of side AV connection cable (RED & WHITE)
to enable sound connection when connecting a device to your TV by using PC or
COMPONENT VIDEO input.
