For added protection for this product (receiver) during a lightning storm, or when it is left unattended and
unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system.
This will prevent damage to the product due to lightning and power-line surges.
Lines.
Power Lines.
An outside antenna system should not be located in the vicinity of overhead power lines or other electric light
or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna
system, extreme care should be taken to keep from touching such power lines or circuits as contact with
them might be fatal.
5
Overloading.
Overloading.
Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.
Heat.
Heat.
The product should be situated away from heat sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.
Cleaning.
Cleaning.
leaning
Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use
a dry cloth for cleaning.
Servicing.
Servicing.
Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.
Service.
Damage Requiring Service.

conditions:
- When the power-supply cord or plug is damaged.
- If liquid has been spilled, or objects have fallen into the product.
- If the product has been exposed to rain or water.
- If the product does not operate normally by following the operating instructions. Adjust only those
controls that are covered by the operating instructions as an improper adjustment of other controls may
result in damage and will often require extensive work by a qualified technician to restore the product to
its normal operation.
- If the product has been dropped or the cabinet has been damaged in any way.
- When the product exhibits a distinct change in performance.
Whenever you connect all external A/V equipment to your television, ensure that all equipments are
switched off. Also refer to the user manual supplied with your A/V equipment for detail connection
instructions and associated safety precaution.
The mains plug is used as the disconnect device. The disconnect device shall remain readily operable.
* The socket-outlet shall be installed near the apparatus and shall be easily accessible.

1-2. Safety precautions for service.
When moving or laying down a TV set, at least two people must be working. Avoid any impact towards the
TV set.
Do not leave the broken TV set on for a long time. To prevent any further damages, after check the
broken set s condition, make sure to turn the power (AC) off.
When opening the back cover, turn off the power (AC) to prevent electric shock. When a TV set is on,
high voltage and high current exist inside the set.
When loosening screws, check the connecting position and type of the screw. Sort out the screws and
store them separately. Because screws holding PCB are working as electric circuit grounding, make sure
to check if any screw is missing when assembling.
A TV set contains different kind of connector cables. When connected or disconnected connector cables,
check the direction and position of the cable beforehand.
When disconnecting connectors, unplug the connectors slowly with care.
Connectors are designed so that if the number of pins or the direction does not match, connectors will not
fit. When having problem in plugging the connectors, make sure to check their kind, position, and
direction.

And each graphic input signal is transmitted to scaler IC of 24-bit RGB signal, HDMI audio signal is
transmitted from ADC to audio processor.
6-2. Video Input Process.
Processing From video input port to video decoder as a bellows,
1) AV1 Input Signal : Decoder Pin 58 from CVBS signal.
2) AV2 : Decoder Pin 57 from AV2 CVBS signal.
3) TUNER : Decoder Pin 59 CVBS signal of Tuner.
Video signal from CVBS and Y, C signal of decoder is transmitted to scaler with 8Bit CCIR656 format.
16
6-3. Video Output Process.
Signal from ADC and video decoder is transmitted to Scaler PW218, actually displaying on the screen,
output signal through LVDS interface is displayed on LCD or PDP panel.
6-4. Audio Input & Output process.
Audio signal from Audio Processor is processed from audio AMP to speaker as a bellows,
1) Tuner Input : Pin 67 of audio processor from tuner SIF signal.
2) PC Input : Pin 53, 54 of audio processor from PC audio signal.
3) DVI Input : Pin 56, 57 of audio processor from DVI audio signal.
4) Component 1 : Pin 50, 51 of audio processor from component 1 signal.
5) Component 2 : Pin 47, 48 of audio processor from component 2 signal.
6) AV 1/2 : Pin 59,60 of audio processor through MUX audio signal from AV 1/2.
7) HDMI : Pin 19,20,22 of audio processor from HDMI I S(Inter-IC Sound) of ADC pin 96, 97, 98.
