SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An isolation Transformer should always be used during
the servicing of a receiver whose chassis is not isolated from
the AC power line. Use a transformer of adequate power rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace
it with the specified.
When replacing a high wattage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor
between a known good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC
voltmeter with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC
voltage measurements for each exposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS which is
corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.
Leakage Current Hot Check circuit
http://www.DataSheet4U.net/
AC Volt-meter
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source,
connect an electrical jumper across the two AC plug prongs.
Place the AC switch in the on position, connect one lead of
ohm-meter to the AC plug prongs tied together and touch other
ohm-meter lead in turn to each exposed metallic parts such as
antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.

1. HDMI(DVI VIDEO) / AUDIO INPUT / RGB INPUT
Connect the monitor output socket of the PERSONAL COM-
PUTER, DVD or STB to this socket.
Note: If you want to use RGB/DVI audio, we strongly recom-
mend that you use the cable that has a core, or the EMI Filter
core along with separate cable.
5. VARIABLE AUDIO OUTPUT
6. EURO SCART SOCKET
Connect the euro scart socket of the VCR to these sockets.
Note: If you want to use the EURO scart cable, you have to
use the signal shielded Euro scart cable.
2. CONTROL LOCK / REMOTE CONTROL
7. ANTENNA INPUT
3. RS-232C INPUT(CONTROL/SERVICE) PORT
Connect to the RS-232C port on a PC.
4. COMPONENT INPUT
Connect DVD video outputs to Y, PB, PR of COMPONENT
INPUT and audio outputs to Audio sockets of AUDIO INPUT.
AUDIO/VIDEO IN SOCKETS (AV4)
Connect the audio/video out sockets of external equipment to
these sockets.
S-VIDEO/AUDIO IN SOCKETS
Connect the S-VIDEO out socket of an VCR to the S-VIDEO
socket.
Connect the audio out sockets of the VCR to the audio sock-
ets as in AV4.
8. POWER CORD SOCKET
This set operates on an AC power. The voltage is indicated on
the Specifications page. Never attempt to operate the set on
DC power.
